Firstly, you have an error on line 96. To resolve this issue, go to line 12 and put extra delegates like UINavigationControllerDelegate and UIImagePickerControllerDelegate. Secondly, the reason why you only see a white screen is because in the Photos array, you don't have a single element inside which means no photos to display, so there will be 0 collection view cells displayed and hence there will be a white screen. |
