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. CloudKit automatically configures every CloudKit-enabled app out of the box to have a public CKDatabase (all users of the app can see everything) and a private CKDatabase (each user sees only their own data). 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. I'm going to be using our sample application. At least one real device To send and accept share invitation(s). 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. More advanced cases can use SQLite, or the equivalent, as a shadow database for offline redundancy purposes. This is your Destination entity in Core Data. 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.

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. The CKShare object may also be configured with title and icon information to be included in the share link message. Note that the same code will work for macOS clients as well, with slight adjustments for differences in how notifications work on that platform. I needed a way to ensure they all work correctly. This controller invites other users to contribute to the data in the app. But in my application, I took a slightly different approach. In a CloudKit database-- for example, the .private database-- NSPersistentCloudKitContainer typically manages a private zone to store the objects an application creates. to present information about shared objects. they would see my two zones that I share with them, and any other zones they are a participant on, So how does NSPersistentCloudKitContainer. Once youve completed that task, set showShareSheet, which presents CloudSharingView, to true. to test these decision points by injection. This takes you to a screen to add a recent destination you visited. Here I'm setting the isSharedBlock to call the contains method of the set I created.
