I am developing an iOS application and trying to add launch screens. Although I only support iOS 9.0 and later, I have added a launch screen for iOS 6.0 and later. Despite this, for some reason, I still get the following error:
"IPhone Retina screensaver (4 inches) for iOS 7.0 and later is required"
When adding images and saving, the error will temporarily disappear. But when I launch the application on any device (via Simulator), the error is returned. Also, the startup screen does not appear.
YES, I know that there are several threads in Stackoverflow (examples are given at the end) mentioning this error . I looked through them and did not help me, because they were either for an older version of Xcode, or the problem was not the same as mine.
I am using Xcode 7.3.1 with Swift 2.2
