This happened to me just today, only after I added a .png image with 'hide extension' ticked in the get info. (Right click image) Ths image was added to the file directory of my Xcode project.

When unticked box and re-adding the the .png image to directory of Xcode, I then Cleaned and Built and worked fine after that, a very strange bug if you ask me.

2. opened Xcode it rebuild certificate;
3. ran app on device successfully.
