Does the document directory is removed automatically in iOS apps?

Question

I've a simple question to the document directory. I build the folder by the following Swift statement:

open static let DOC_FOLDER : String = try! FileManager.default.url(for: .documentDirectory, in: .userDomainMask, appropriateFor: nil, create: false).path

I store some files and create subfolders there.
And now I'm not sure whether the whole folder structure is deleted automatically if I uninstall the app or does the directory still exists and is only not accessible?

Answer 1

When the user uninstalls the app, the entire sandbox is wiped clean. If the user installs the app again, your app will need to recreate the folder structure again.

Answer 2

Put user data in Documents/. User data generally includes any files you might want to expose to the user—anything you might want the user to create, import, delete or edit. For a drawing app, user data includes any graphic files the user might create. For a text editor, it includes the text files. Video and audio apps may even include files that the user has downloaded to watch or listen to later.

=> If you uninstall the app, the folder will be removed
