Swift should support iOS app "resetting" — the equivalent of force quitting and restarting. This is important for iCloud sync between devices

Users don't care about the app architecture. They just want an app that is stable and doesn't crash.

An app reset for iCloud sync may result in a suboptimal UX but it is better than an unstable app or one that doesn't support iCloud sync.
