There are very convoluted ways to backup and restore apps and data on iOS, even to go back to an older version of an app, but they require a lot of fiddling (literally, with fiddler), and if the app has changed its data format you need to have a backup of the old data in a format that can be restored. It would be nice if apple added time machine to iOS and iPadOS and let you restore any previous version of an app and its data. This example demonstrates that the walled garden is not as safe as people think it is. Granted, reviewing every update in detail is a monumental task. Then again, this is why apple takes the 30%. I don't believe apple can catch all bad updates before they get sent out. An easy ability to revert to an older version of an app and its data would be very useful. Given how an iCloud-powered time machine for iOS would slurp up iCloud storage and push people to higher paid tiers I'm amazed they haven't done it before.
