问题 I am trying to create an iOS app using Swift to capture images and let the user save a selected portion of the image.

问题 I've developed my application using my 3G device to test with. Upon giving this to a friend to test, he's noticed that it crashes..I've had a look at the crash log, but it's not much use except for the "EXC_BAD_ACCESS" statement after a few memory warnings.
