Synchronize values across devices using iCloud.

- Important: You need to enable the `iCloud` capability in the Signing and Capabilities tab in Xcode and then enable Key-value storage in the iCloud services.

- If there is a conflict, it will use the latest change.

- It uses [`NSUbiquitousKeyValueStore`](https://developer.apple.com/documentation/foundation/nsubiquitouskeyvaluestore) internally.
