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. by the presence of their objectID in this set. Then, open the starter project. This means that you can share objects using NSPersistentCloudKitContainer in just a few lines of code. In the iCloud section, tap the + button underneath Containers to add a custom container. The final step is to add the Background Modes capability and enable Remote Notifications. An object that represents activity in a persistent CloudKit container. Next, I'll tap Mail and invite Jermaine and Mary. For each participant, NSPersistentCloudKitContainer manages objects in two CloudKit databases, the .private and the .shared database. that controls who can access these zones that I own. Thanks for contributing an answer to Stack Overflow! If I tap on it, I can see that the Edit button is disabled and the participants entry for Jermaine shows that he is a Read-Only participant on the share. But in my application, I took a slightly different approach. The largest and most up-to-date collection of courses and books on iOS, After adding a few of these customizations, it became obvious I needed a way to ensure they all work correctly, which brings me to the main reason the SharingProvider exists: testing. This framework (https://github.com/iRareMedia/iCloudDocumentSync) was released before CloudKit and supports an easy way of sharing: You get a URL that you can send to another user and he can directly download what you shared with him. However, such conflicts can arise from other circumstances. 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. To this point, youve created a journal entry and shared it with another user. For example, this user may have a private zone and a shared zone that they own in their .private database. Find centralized, trusted content and collaborate around the technologies you use most. The following code, for example, creates a CKShare object containing the record to be shared and configured for read-only access: Once the share has been created, it is saved to the private database using a CKModifyRecordsOperation object. Theres just one catch: This controller is a UIKit controller, and your app is SwiftUI. Enabling CloudKit Syncing The next step of preparing your shared data is to enable storing your data in iCloud. Look for the ToolBarItem that contains the Text("Edit") button. For this example, youll use CKAsset to store the note text. and how that affects the types of experiences you can build. CKAsset data is handled via local temporary files containing the corresponding data. CloudKit: For managing structured data and sharing data among users. Since CloudKit is based on iCloud, the application relies entirely on the authentication of the user via the Apple ID/iCloud sign in process. So I'll tap Mail and then enter the information for my friends. These days, modern mobile application development requires a well thought-out plan for keeping user data in sync across various devices. Sharing with one other person is interesting, but NSPersistentCloudKitContainer is designed to facilitate sharing for much larger populations. And finally, we'll briefly discuss how NSPersistentCloudKitContainer can help you enable some additional protection for sensitive data stored in iCloud. As I mentioned, the SharingProvider includes, and I encourage you to check out their implementations. - Accepting a shared note will now move it to the top level of your notes folder - Fixed a bug where clicking on the month name on macOS shifted the calendar weeks - Improved website titles when pasting a web link in NotePlan - iCloud Drive sync is now hidden as a sync option for new users since Cloudkit provides a better sync experience Notice the role and permission for each user. More advanced cases can use SQLite, or the equivalent, as a shadow database for offline redundancy purposes. Since this is a first example of using an operation, here are a couple of general observations: First, all CloudKit operations have custom completion closures (and many have intermediate closures, depending on the operation). manages objects in two CloudKit databases. with the CloudKit server in the container associated. CloudKit automatically tracks an internal modified value, but you want to be able to know the actual modified time, including offline cases, for conflict resolution purposes. Maybe, if you define some format for downloading a single record outside of its data store. Add the following method to your extension: With this code in place, you can determine if the destination is already shared and then take the proper action. It is also possible to serialize CKRecords directly to and from local storage. and a shared zone that they own in their .private database. Participants can have different roles and permissions that constrain how they can act on a particular set of objects, which brings us to the second key concept: how NSPersistentCloudKitContainer and CloudKit structure these shared objects. . Now I'm going to add a new post, give it a title, and tap Done. Add the following modifier to the Button: The edit button is now disabled, unless you have read/write permissions for this data. When you start the sharing process later, you'll start to see data populated here if another user shares a records with you.

Here I used isShared to decide whether or not to convert the title of a post to an attributed string and prefix it with the person.circle symbol to show that the post is part of a share. Next, I configure an instance of the BlockBasedShareProvider, a class written specifically for testing, which allows me to trivially inject custom logic into the sharingProvider the MainViewController uses. Finally, I'll tap Send to send the email. The first is the notion of a set of actors. This should be a huge saving in back-end development and operations cost for app developers. Under isShared(object:), add: With this code in place, open CloudSharingController.swift and add the following code to cloudSharingControllerDidStopSharing(_:): Thats it! CloudKit - How to share multiple records and retrieve shared records? Since CloudKits notifications are built on top of the iOS notification system, you have to be on the lookout for these conditions. Loading a note is very straightforward. New in iOS 15 is acceptShareInvitations(from:into:completion:). Look at the share options. Owners create and share objects with a set of participants. 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:). Then, I set its CloudKit container options databaseScope property to .shared. Select your desired delivery method and send the invitation. CloudKit organizes data via a hierarchy of classes: CKContainer, CKDatabase, CKRecordZone, and CKRecord. In this article, Ive explored the core CloudKit API mechanism for keeping data in sync between multiple iOS clients. Here I've chosen four friends to share the photo with. Apps can support such use cases by moving user data to CloudKit and implementing a data sharing flow that includes features like share management and access control. 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. This logic first checks to see whether the object is shared. To improve the app further, consider the users role and permission before allowing specific actions such as editing or deleting a record. Tapping that brings up the set of participants. In this post, we will talk about zone sharing. They build on Apples notification infrastructure to allow various clients to get push notifications when certain CloudKit changes occur. Because there's no root record, NSPersistentCloudKitContainer also has to understand how the concepts of owners and participants apply to the entire record zone. Accepting share invitations and fetching the shared data. of shared objects without ever talking to the CloudKit server. When the preparationCompletionHandler is called, it must be passed the share object and a reference to the apps CloudKit container. Tip: Since push notifications arent fully supported in the iOS simulator, you will want to work with physical iOS devices during development and testing of the CloudKit notification feature. We call them the owner and the participants. You can think of the name as the primary key of the record in a simple database sense (names must be unique, for example). The app designer is always in the best position to define rules for these situations, which can include everything from context-aware automatic merging to user-directed resolution instructions. Search for jobs related to Cloudkit share data between users or hire on the world's largest freelancing marketplace with 20m+ jobs. The end goal is not only to display shared entries but also to get information about the people participating in the share. that aren't already encrypted today in production. In this simple Note application, with a single user switching between devices, youre not likely to see too many conflicts in a live concurrency sense. Well, let me show you. Pauls been a developer for nearly three decades, working with many tech stacks but with a focus on Apple. and automatically assigns records to them. What is the easiest way to share files between users with CloudKit? Let's look at that change in a bit more detail. Then, it sets the persistent store based on the scope. Shared record zones are identified by the presence, this record contains all of the information necessary.
