If one does not need Base internationalization, one can turn it off in the project settings - this fixed the problem in my case:
When turning base internationalization off, the affected files (storyboard, launchscreen) are moved from base.lproj
to en.lproj
. It looks like there are problems when base.lproj is used without at least one (primary) language.
I encountered the problem after creating a new project in Xcode 6.4 and then opening it in Xcode 7.
What I did is change the Localization native development region From China to United States.
I checked the English checkmark in addition to the Base, and it stopped having problems.
