Summary:
It's not possible to detect when a file copied to an app through iTunes is completely transferred rather than partially. To achieve this, please make the device coordinate its writes using the NSFileCoordinator/NSFilePresenter API.

Steps to Reproduce:
1. Open the xcode project
2. Launch the app on a device (not simulator). This app is using NSFileCoordinator/Presenter to watch the Documents folder.
3. Use iTunes to transfer a file to the app

Expected Results:
registered NSFilePresenter should be notified about the change.

Actual Results:
Presenter is not notified.

Version:
iOS 10
