What platforms are supported by these iCloud patterns?

The patterns cover iOS 5.0+, iPadOS 13.0+, and macOS 10.7+, including modern updates for iCloud Drive and the Files app.

Why is NSFileCoordinator emphasized in this skill?

NSFileCoordinator is critical for iCloud development because it prevents race conditions between your app and the system's ubiquitous daemon, ensuring files aren't corrupted during sync.

Should I use this skill for database synchronization?

No, this skill is specifically for file-based synchronization. For structured data or relational databases, you should use the axiom-cloudkit-ref skill instead.

Does this skill cover NSUbiquitousKeyValueStore?

Yes, it includes patterns for syncing small preferences (under 1MB) across devices using the key-value store API.
