cloudkit share data between userscloudkit share data between users

This chapter has covered the basics of CloudKit sharing, a topic which will be covered further in a later chapter entitled An iOS CloudKit Sharing Example. He loves solving hard problems. Next, I'll tap Mail and invite Jermaine and Mary. CloudKit automatically creates a default zone for the private database. Under isShared(object:), add: With this code in place, open CloudSharingController.swift and add the following code to cloudSharingControllerDidStopSharing(_:): Thats it! Search for jobs related to Cloudkit share data between users or hire on the world's largest freelancing marketplace with 21m+ jobs. I get a Error Fetching Record error, even if I copy and paste it in. But our applications are usually designed, NSPersistentCloudKitContainer has to also help us make sense, of all of these objects so that we can build. Last, if the current user of that share is the owner, returns. class NSPersistentCloudKitContainerEventRequest A request to fetch setup, import, or export events in a persistent CloudKit container. directly to specific call sites in my application. Go to the first device you created the share from, because you need to be the Owner to access the Share Options. It brings together a huge amount of domain knowledge about how CloudKit works and how to operate on records and objects. It checks databaseScope and determines whether its private or shared. A user of an app could, for example, make one or more records accessible to other users so that they can view and, optionally, modify the record. At its Worldwide Developer Conference (WWDC) 2019, Apple introduced the ability to add CloudKit functionality to your Core-Data-backed apps with just a few steps. Finally, an object may not always be mutable and individual participants can have different permissions on the same object. Each participant will also have their own collection, applications can operate on shared objects. Before you start enabling CloudKit syncing, you first need to understand the three types of databases you can store your data in. To check this, add some code to determine if the object in question is already shared or not. Finally, I'll tap Send to send the email. by the presence of their objectID in this set. Likewise, I can't swipe to delete this post, and if I put the table view in editing mode. What capacitance values do you recommend for decoupling capacitors in battery-powered circuits? How might we build an experience like this? Figure 48 2 shows an example share options settings screen: Once a method of communication has been selected by the user from the cloud sharing controller, the completion handler assigned to the controller will be called. Second, enable the iCloud capability in your app. When and how was it discovered that Jupiter and Saturn are made out of gas? Now, youll resolve this error. I might need to know whether or not an object is shared. For each participant, NSPersistentCloudKitContainer manages objects in two CloudKit databases, the .private and the .shared database. The final step is to set the cloudKitContainerOptions property for the sharedStoreDescription you created. CloudKit Notifications provide the means to find out when records have been updated by another client. But how does all of this work? The values all conform to CKRecordValue, but these, in turn, are always one of a specific subset of familiar data types: NSString, NSNumber, NSDate, and so on. I've already modified it to support sharing posts with different iCloud users. When the user taps the link that was shared earlier and accepts the invitation, the delegate calls this method and launches the app. that controls who can access these zones that I own. This doesn't seem to work. Then, select the CloudKit checkbox to enable the feature. The first step does a one-time setup in preparation for writing the record, and the second step passes the assembled record down to the singleton CloudKitNoteDatabase class. whether or not to convert the title of a post. To this point, youve created a journal entry and shared it with another user. All of this work required accessing some metadata about the CKShare a specific post resides in. Loading a note is very straightforward. Open CoreDataStack.swift. So I'll tap Mail and then enter the information for my friends. This is a thorny problem with many gotchas and pitfalls, but users expect the feature and expect it to work well. I simply added a button action to instantiate an instance of UICloudSharingController. In a CloudKit database-- for example, the .private database-- NSPersistentCloudKitContainer typically manages a private zone to store the objects an application creates. NSPersistentCloudKitContainer also has to understand, how the concepts of owners and participants apply, Let's imagine I have a collection of people. It's called the SharingProvider. At least one real device To send and accept share invitation(s). Hi. Click Query Records to see a listing of the record(s) you created in the app earlier! I'll give it a simple title-- "Sharing demos are great"-- and tap Done. for the view controller, completing the injection. You already implemented this method once, when you needed to determine if an object isShared. directly to NSPersistentCloudKitContainer. Select recordName from the list and ensure the index type is Queryable. Rather than relying on individual notifications to give you detailed knowledge of what change an individual notification represents, you use a notification to simply indicate that something has changed, and then you can ask CloudKit whats changed since the last time you asked. These can be normal push notifications familiar to iOS users (such as sound, banner, or badge), or in CloudKit, they can be a special class of notification called silent pushes. We call them the owner and the participants. Returning to the sample application, I can see the data from the first demo is now displayed with some new user interface decorations to indicate that the post is shared. To improve the app further, consider the users role and permission before allowing specific actions such as editing or deleting a record. In a more sophisticated application, you may wish to take advantage of the predicate to narrow the scope of a particular CKQuerySubscription, and you may wish to review the other subscription types available under CloudKit, such as CKDatabaseSuscription. CloudKit - How to share multiple records and retrieve shared records? . that is allowed to operate on those objects in some way. Finally, I invoke UICloudSharingController's completion block with the results provided by NSPersistentCloudKitContainer, which tells it I'm ready to continue the sharing flow. Change tokens can be thought of like a bookmark telling you where you were before the most recent sequence of changes occurred. enum NSPersistentCloudKitContainer.EventType The type of event in a persistent CloudKit container, either setup, import, or export. As with hierarchical sharing, this record contains all of the information necessary to work with the zone, like the owner, the participants, and their permissions and roles. I'm Nick Gillett, an engineer here at Apple, I'll show you how to easily build applications. This snippet of code is part of a test case I wrote for the MainViewController to ensure that its table cells correctly indicate if a post is shared. This logic first checks to see whether the object is shared. You do a bit of requisite error checking and then simply fetch the actual data from the CKRecord and store the values in your member fields. Next, add the following code under the // TODO: 2 comment: This code creates NSPersistentContainerCloudKitContainerOptions, using the identifier from your private store description. This might not always be the best outcome for professional apps, but its not bad for a first rule and, for this purpose, serves to illustrate the mechanism by which CloudKit passes conflict information back to the client. Apple added sharing to CloudKit. It's been my pleasure to introduce just some of the changes we've made to NSPersistentCloudKitContainer to support sharing. When you create a destination, the data is being persisted via Core Data locally in your app. Each of these is mirrored to a persistent store. Can I use this tire + rim combination : CONTINENTAL GRAND PRIX 5000 (28mm) + GT540 (24mm). But in my application, I took a slightly different approach. If you have any questions or comments, please join the forum discussion below. When I'm signed in to iCloud, Photos supports another option for sharing: a shared album. A participant is any other iCloud account. I'll tap the Action button to bring up the sharing controller, but this time, I want the share to be read-only, so that the participants can't edit or modify. With this code in place, navigate back to DestinationDetailView.swift to present CloudSharingView. At this point, if you shared the invitation via text message, open Messages and tap the invitation. Photos implements a system control here in the lower left that allows me to call up an Action sheet. CloudKit supports both structured and bulk data. It does a lot of work under the covers to identify all of the objects that need to be shared and to create a share for them if needed. Then, it sets the persistent store based on the scope. Each of these is mirrored to a persistent store in my application, one using the .private database scope and the other using the .shared database scope. This is your Destination entity in Core Data. How can I change a sentence based upon input to a command? Here, youll add the code to accept the share. Manage Settings In addition to sending a share link, the app must also be adapted to accept a share and fetch the record for the shared cloud database. Click Add Basic Index. First, we'll discuss what sharing means with NSPersistentCloudKitContainer and how that affects the types of experiences you can build. if the provided objectID is in sharedObjectIDs. Our users need all of that information so that they can make good decisions about the objects they choose to share. Sync user data between multiple apps from the same developer. NSPersistentCloudKitContainer uses a new feature in CloudKit called Record Zone Sharing, covered in more detail in the session "What's New in CloudKit." If I tap on it, I can also see the participants, displayed at the bottom of the detail view controller. It comes with a Dictionary of contained CKErrors that deserve more careful inspection to figure out what exactly happened during a compound operation. Sharing with one other person is interesting, Each of these participants will be able to access. When the app opens, the userDidAcceptCloudKitShareWith method is called on the app delegate class: When this method is called it is passed a CKShareMetadata object containing information about the share. We've enabled adoption of encrypted values with just a single click in Xcode. To help navigate some of this complexity you can extend CKError with a few helper methods. Next, add the following code below the // TODO: 3 comment: This code adds your shared NSPersistentStoreDescription to the container. Because there's no root record, NSPersistentCloudKitContainer also has to understand how the concepts of owners and participants apply to the entire record zone. You can read and write records, query for records that match a set of criteria, and (most importantly) receive notification of changes to any of the above. In my .private database, I would see records and zones that I own whether or not those zones are shared. Instead of invoking methods on NSPersistentCloudKitContainer. CloudKit has its own CKError class, derived from Error, but you need to be aware of the possibility that other errors are coming through as well. Tapping that brings up the set of participants. Both the CKShare and associated CKRecord object are then saved to the private database. Thus, your AppDelegate should call application.registerForRemoteNotifications in didFinishLaunchingWithOptions and implement didReceiveRemoteNotification. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. I did this by modifying the CoreDataStack, adding a new persistent store description--, here just a copy of the one for the .private store, Then, I set its CloudKit container options, to be configured to mirror persistent stores, I adopted a new method on NSPersistentCloudKitContainer, share(_ managedObjects: to share: completion:). This is because you havent accepted the invitation yet. Note that the same code will work for macOS clients as well, with slight adjustments for differences in how notifications work on that platform. When you app is opened with such a link, then you can download the CKRecord and you will have the file in a CKAsset. NSPersistentCloudKitContainer shares objects. to write all of these tests and structure the application. Next, I configure an instance of the BlockBasedShareProvider. The UICloudSharingController is a view controller that presents standard screens for adding and removing people from a CloudKit share record. In anticipation of this, split the save function into two steps. The code above stores a reference to each store when its loaded. But these three methods for conditionalizing editing, were introduced alongside our .public database support, You can use these methods in your applications. You now see the shared entry on your second device. To get the most out of this session, check out our previous videos on NSPersistentCloudKitContainer: "Using Core Data With CloudKit" from WWDC19 and "Sync a Core Data store with the CloudKit public database" from WWDC20. by tapping this person icon in the upper right. In my brief demo, I showed an application that makes use of two CloudKit databases, the .private and the .shared database. At the top right is the edit button, which presents a modal to edit your destinations caption and description. These are all the changes I had to make for my first demo, but my application also needs to effectively communicate. Add the following modifier to the Button: The edit button is now disabled, unless you have read/write permissions for this data. Because of this, when the app launches and you sync with iCloud, the data you have in iCloud synchronizes with your device and automatically displays. Two separate iCloud accounts To initiate the sharing process. of shared objects without ever talking to the CloudKit server. For our purposes, a single view application containing a UITextView with the ViewController as its delegate will suffice. NSPersistentCloudKitContainer automatically syncs. To edit or update the caption or description, tap the destination cell to see the detail screen. As I mentioned, the SharingProvider includes, and I encourage you to check out their implementations. An error occurred when submitting your query. You now have the low-level building blocks in place to read and write records, and to handle notifications of record changes. Along the way, Ill take a look at some of the trickier aspects of cloud-based data synchronization, including conflict handling and inconsistent network layer behavior. manages objects in two CloudKit databases. I'll open the CoreDataCloudKitDemo managed object model, and there's a specific property on the post entity I want to show you called location. Did you figure it out? Have a question? For example, a user may have made edits on one device while in airplane mode, and then absent-mindedly made different edits on another device before turning airplane mode off on the first device. Now that you have the method to perform the share, you need to present the CloudSharingView when you tap the Share button. Every app automatically gets a default CKContainer, and a group of apps can share a custom CKContainer if permission settings allow. So let's take a look at exactly how NSPersistentCloudKitContainer shares objects. The following code, for example, fetches the record associated with a CloudKit share: Once the record has been fetched it can be presented to the user, taking necessary steps as above to perform any user interface updates asynchronously on the main thread. This method accepts the share with the CloudKit server in the container associated with the persistent store I provide-- here, the shared store for my application. Well, let me show you. The exact version of the record you tried to save. NSPersistentCloudKitContainer manages these zones and automatically assigns records to them. Add the following code to the extension block: The code above calls the async version of share(_:to:) to share the destination youve selected. Apple has been adding data sharing into many of its first-party apps, including: Files Reminders Notes Calendar Photos Activities Find My Maps Music Health With a free Kodeco account you can download source code, track your progress, For your Note app, you can use the default container. This is the default database that data gets written to. Asking for help, clarification, or responding to other answers. Due to network latency, airplane mode, and such, CloudKit will internally handle retries and such for operations at a qualityOfService of utility or lower. When the app comes up, youll notice the shared journal entry doesnt show up. Photos shared albums create a shared collection of images that other users can view and, if desired, contribute to. I and, if allowed, other participants can add. Does Cast a Spell make you a spellcaster? Is something like this (or even better) available with the new CloudKit? If you sent the invitation from a real device, that can be a simulator. persistentContainer calls this method. Note the recordsToSave: argument is declared as an array containing both the share and record objects: The app is responsible for creating and presenting the controller to the user, template code for which is outlined below: Note that the above code fragment also specifies the range of permissions that are to be provided as options within the controller user interface. To begin the sharing process, add the following code to your persistentContainer below the // TODO: 1 comment: This code configures the shared database to store records shared with you. These options are accessed and modified by tapping the Share Options item at the bottom of the cloud sharing controller view. Another user will see a different set of zones in their .private and .shared databases, depending on whether or not they are the owner of those zones. But ideally, we would have a single place. The unique record id name doesn't seem to be enough to find the record. Stay active, close your rings, and have a great WWDC 2021. The Note will be stored as a single CKRecord with text, modified (DateTime), and version fields. If you've worked with sharing before, you're probably familiar with hierarchical sharing, where these records are associated with a root record called the share. Build apps that share data through CloudKit and Core Data Learn how to easily build apps that share data between multiple iCloud users with NSPersistentCloudKitContainer. Another user will see a different set of zones. If I'm allowed to, I can add records that I own to any of those zones just as they can in the zones that I own. The SharingProvider has methods for binding. Toptal handpicks top iOS developers to suit yourneeds. This involves the creation of a CKFetchRecordsOperation object using the record ID contained within the CKShareMetadata object. share(_ managedObjects: to share: completion:) is a new method designed to pair directly with UICloudSharingController. The way to enable these silent notifications is to set the shouldSendContentAvailable property on the CKNotificationInfo instance, while leaving all of the traditional notification settings (shouldBadge, soundName, and so on) unset. we have built in to NSPersistentCloudKitContainer. However, such conflicts can arise from other circumstances. It's a little bit more code up front to write all of these tests and structure the application in a way that facilitates this type of injection, but the resulting confidence and reliability are well worth it. Finally, I'll tap Send to send the email. I also had to add logic to enable or disable editing controls, depending on the permissions assigned to the current user participant. When storing data via CloudKit, CloudKit Console allows you to interact with the data in question and perform several other functions such as viewing logs. with the CloudKit server in the container associated. As you prepare to present your CloudSharingView, you need this property because the second parameter of CloudSharingView is a CKContainer. Modern mobile application development requires a well thought-out plan for keeping user data in sync across various devices. When a user decides to share CloudKit data, a share link in the form of a URL is sent to the person with whom the data is to be shared. Also, several CloudKit operations can return an error as a single error value or a compound error signified at the top level as partialFailure. Once youve completed these steps, the data in your app then automagically sync with iCloud. To achieve this, iOS 15 introduces share(_:to:). Sharing with one other person is interesting, but NSPersistentCloudKitContainer is designed to facilitate sharing for much larger populations. CloudKit operations provide superior control over the details of how CloudKit does its work and, perhaps more importantly, really force the developer to think carefully about network behaviors central to everything CloudKit does. and operate on the objects I share with them. CloudKit provides much more functionality on top of this, especially for sophisticated data models, public sharing, advanced user notification features, and more. Next, we'll take a deep dive into the mechanics of sharing. a number of API methods to align with each of these concerns. Open CoreDataStack.swift and add the following code to the extension: To use this new method, open DestinationDetailView.swift. Pauls been a developer for nearly three decades, working with many tech stacks but with a focus on Apple. The first change I had to make was to tell NSPersistentCloudKitContainer to mirror the .shared CloudKit database to a new persistent store. If you would like to change your settings or withdraw consent at any time, the link to do so is in our privacy policy accessible from our home page.. With the introduction of CloudKit sharing it is now possible for individual app users to share private database records with other users. Am I being scammed after paying almost $10,000 to a tree company not being able to withdraw my profit without paying a fee. Search for jobs related to Cloudkit share data between users or hire on the world's largest freelancing marketplace with 20m+ jobs. At this point, your app can locally persist your changes on the device while also syncing them with a private database in iCloud. that aren't already encrypted today in production. Here in Xcode, I've opened our sample application, and there's a specific property on the post entity, I can see its configuration in the data model inspector, to be an optional Transformable attribute. Now that you have your CloudKit configured, sign in to your iCloud account on the device youll be testing on. You can download the completed project files by clicking the Download Materials button at the top or bottom of the tutorial. into the sharingProvider the MainViewController uses. Back in CoreDataStack.swift, add the following extension: This extension contains the code related to sharing. Please note all the code has explanatory comments at the key points. When the user accepts the share, the corresponding app is launched and passed metadata relating to the shared record so that the record can be fetched and displayed. The first step is to create a method that prepares your shared data. These values are stored in a new payload on CKRecord called encryptedValues, introduced in the "What's New in CloudKit" session. Also, to change the sharing permissions because it doesnt work properly on a simulator. Build and run again. Share Core Data between users with NSPersistentCloudKitContainer Ask Question Asked 3 years, 7 months ago Modified 1 year, 8 months ago Viewed 3k times 16 Apple introduced the NSPersistentCloudKitContainer with iOS 13 which enable us to use CloudKit with Core Data. Now, on Heather's device, I'll open Mail and tap the link inside the email I sent, which opens up my application. Learn SwiftUI and take your iOS Development to the Next LevelSwiftUI Essentials iOS 16 Edition book is now available in Print ($39.99) and eBook ($29.99) editions.

The final step is to add the Background Modes capability and enable Remote Notifications. It accepts the share and adds the necessary metadata into the sharedPersistentStore. create shares for objects, and accept sharing invitations. Also, a CloudKit record may only be shared if it is stored in a private database and is a member of a record zone other than the default zone. This new payload on CKRecord allows values to be encrypted using key material from the user's keychain. Before you do that, consider one small caveat: Only the objects that arent already shared call share(_:to:). What is the easiest way to share files between users with CloudKit? Saving records is, perhaps, the most complicated operation. Amazing! Synchronizing a Local Store to the Cloud. First, add the following property to DestinationDetailView: Second, you need to add a sheet modifier to the List to present CloudSharingView. Over time, however, Apple has addressed these issues. based on the relationship they have to other objects. Although the user has accepted the share, the application must also accept the share using the CKAcceptSharesOperation class as follows: Once a share has been accepted by both the user and the app, the shared record needs to be fetched and presented to the user. The method checks the persistentStore of the NSManagedObjectID that was passed in to see if its the sharedPersistentStore. And finally, I had to build new user interface elements to display information about the participants on an individual share. Page - Sharing data between User Controls without access to the Page class - Accessing data between user controls WPF - Passing data between user controls in wpf - Pass data between parent child user controls . The CKShare object may also be configured with title and icon information to be included in the share link message. It is important to be aware that when a share recipient accepts a share they are actually receiving a reference to the original record in the owners private database. Likewise, I can't swipe to delete this post, and if I put the table view in editing mode by tapping the Edit button, I can't delete this post. catalogue of 50+ books and 4,000+ videos. and how that affects the types of experiences you can build.
