save and load data after app has been deleted

Question

Is there a way to save data to the iPhone when the app has been deleted so that when the app is reinstalled the app is in the same state it was in before it got deleted? I created an app but when I delete it, it doesn't save and reload the data.

Swift
Xcode

Answer 1

Two things to consider.

There is no way to do something when the app has been deleted. If you want to save your app state, you may need to save it always when it is changed.
Normal app storages are deleted when the app is deleted. You need to save your app state somewhere else than normal app storage.

Okay how do I save it somewhere else? Is there a way to save it somewhere else other than a server?

Keychain is the only storage that I know which is preserved even when the app is deleted.
Using a server can be a good option and you should better not omit it.
