iOS 15.2 beta 3 - subscriptions not triggered?!

Problem still present on a device with 15.2 beta 4.

Things I've tried in the meantime:

• resetting the Development environment from CloudKit Dashboard, deleting and reinstalling the app
• tried using a different CloudKit Container
• tried switching between manual and automatic provisioning profiles

No changes.

Meanwhile, a 15.1 device still happily working correctly, getting notified, working as intended

Apple, it looks that you have a problem with subscriptions created via async/await methods.

Apple GitHub account has CloudKit sample code.

“CloudKit Samples: Private Sync with Subscriptions and Push“ provides 2 branches:

• “main“ uses CKOperations to communicate with private CKDatabase - https://github.com/apple/cloudkit-sample-privatedb-sync/tree/main
• “concurrency” uses async/await methods to communicate with private CKDatabase - https://github.com/apple/cloudkit-sample-privatedb-sync/tree/swift-concurrency

Other than that the code is essentially the same. (NOTE: To run the concurrency version, one has to update database.modifySubscriptions method to include the “deleting“ parameter.)

Subscriptions are NOT TRIGGERED for the async/await version on a device running iOS 15.2 beta 3 and 4.

At least now I know I am not crazy. I'm going to ditch the async/await CloudKit methods.
