I have this environment:
OS X EL capitan 10.11.1 | Xcode 7.1 and test in real device iPhone4 with iOS 7.1
My Deployment target is 7.0 and use Assets Catalog for Launch Screen and images.
I don't have any problems in iOS 8 and 9 but in iOS 7 i have Black screen.
I tried several answers found in Stackoverflow as: 1) Use LaunchScreen.storyboard 2) Add info.plist "Launch screen interface file base name" 3) Remove complete LaunchScreen completely.
All with no success.
Any other ideas?
