iOS Question Restart IOS Simulator cleans up all app data

Are you sure that it is deleted? It should be kept automatically.

I have local SQLite DB and read data from it.
After restarting simulator db is empty.

I tested it and the files are not deleted.
You can check it with this code:

I investigated issue and found that that the root cause is a bit another name returned by File.DirLibrary or File.DirDocuments after app or simulator restart.
In order to implement internal app db management logics I store value of File.DirLibrary in the file and compare it with the current value of File.DirLibrary. On Android it worked correctly. On iOS doesn't. I modified algorithm for iOS to consider the feature I described above. Now it works correctly on Android and iOS.
