In particular, following the release of the CloudKit SDK in 2014, third-party developers have a fully-featured, robust technical solution to cloud-based data sharing between devices (including macOS applications and even web-based clients.). In Core Data, we think of our objects in terms of NSManagedObject. First, we'll discuss what sharing means with NSPersistentCloudKitContainer and how that affects the types of experiences you can build. I simply give the new album a title and then tap Next to choose the set of participants. Using a single managed object context, my application can access data in both stores. Sharing with one other person is interesting, Each of these participants will be able to access. we need to identify two crucial concepts for sharing. Once youve completed that task, set showShareSheet, which presents CloudSharingView, to true. Over 300 content creators. CloudKit supports both structured and bulk data. Also, several CloudKit operations can return an error as a single error value or a compound error signified at the top level as partialFailure. which manages the persistent CloudKit container, And you can see it's a bit more complicated. 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:). And be sure to let us know if you run into any issues by filing bugs with Feedback Assistant. Lets look now at a layer built on top of that to manage these operations in the context of a specific Note. To view the purposes they believe they have legitimate interest for, or to object to this data processing use the vendor list link below. Hiring?

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. To understand these challenges a bit more clearly, we need to identify two crucial concepts for sharing. shared CKRecords are contained inside a shared CKRecordZone. Now that youve sent an invitation to your second user, you need to set the app to accept the invitation and add the data into the shared store. Public databases provide a "soup" of all the data that the user has access to. If its not shared, create the share from the destination object.

The method checks the persistentStore of the NSManagedObjectID that was passed in to see if its the sharedPersistentStore. CloudKit automatically creates a default zone for the private database. After the share is accepted, NSPersistentCloudKitContainer automatically syncs all of the shared objects into the local store. Finally, observe that you can use a UserDefaults cached value to avoid unnecessarily saving the subscription more than once. Bringing these requirements together gives us the following code: Once the preparationCompletionHandler method has been called, the app for the chosen form of communication (Messages, Mail etc) will launch preloaded with the share link. . These days, modern mobile application development requires a well thought-out plan for keeping user data in sync across various devices. Instead of invoking methods on NSPersistentCloudKitContainer.
