I want my app only to run in iPhone 4 and iPhone 5 resolution. In Xcode 6, you just needed to delete the Launch Screen file in order to lower the resolution ( How to disable iPhone 6 native resolution?)
However, now if you don't have a Launch Screen, your lower resolution apps will show up with black bars on top and bottom. So to fix this you have to add a Launch Screen Storyboard (iOS 9 Xcode 7 - Application appears with black bars on top and bottom)
Is there any way to run apps on lower resolutions without having these black bars show up?
