I have implemented CKSyncEngine synchronization, and it works well. I can update data on one device and see the changes propagate to another device quickly. However, the initial sync when a user downloads the app on a new device is a significant issue for both me and my users. One problem is that the sync engine fetches deletion events from the server. On a new device, the local database is empty, so these deletions are essentially no-ops. This would not be a big problem if there were only a few records or if it was fast. I measured the initial sync and found that there are 150 modified records and 62,168 deletions. Counting these alone takes over five minutes, even without processing them. The deletions do nothing because the local database has nothing to delete, yet they still add a significant delay. I understand that the sync engine ensures consistency across all devices, but five minutes of waiting with the app open just to insert a small number of records is excessive. The problem would be worse if ther

I tried making a concurrency-safe data queue. It was going well, until memory check tests crashed. It's part of an unadvertised git project. Its location is: https://github.com/CTMacUser/SynchronizedQueue/commit/84a476e8f719506cbd4cc6ef513313e4e489cae3 It's the blocked-off method `memorySafetyReferenceTypes' in SynchronizedQueueTests.swift. Note that the file and its tests were originally AI slop.
