XCode uploading data files to iPad "Permission Denied"?

Question

I am trying to upload some modified data files to my app using XCode 5. My app takes makes modifications to an sqlite database that I want to be able to restore easily for testing purposes.

So I downloaded the datafiles from the app (containing the db) with the intention of reuploading it later after the app does some modifications to the db.

I download the files through the Organizer -> My iPad -> Applications -> Download (under Data files in Sandbox). I want to reupload by the Upload button right next to it.

However when I try to upload it returns the error "Permission Denied". There is nothing in the device logs indicating what exactly what permissions I need.

Does anyone know of the proper build settings or device settings I need to be allowed to upload modified datafiles for my App?

Answer 1

I've found that the cached Snapshots can interfere with the upload process. If you go into the downloaded app data folder and remove the Snapshot image, then try to re-upload to the device, it should work.

Answer 2

Verify the App isn't running on the device (even in the background), as that can lock files in its data directory.
