title: saving an image to photos library using Swift 2.0
body: <p>I'm getting a problem highlighted in red above. When I take a picture and press use photo, it won't let me save the photo I took to the photo album on my iPad. I have looked at other ways but me being a beginner to iOS development, I'm unsure of how to fix this problem. I sometimes get a sigabrt error too.</p>
