libc++abi.dylib: terminating with uncaught exception of type NSException

I'm working with VersionControl as soon as this error occurs. I did step back to previous commit but the error keeps coming. I'm pretty sure it's nothing in my code.

I also tried all solutions from Build universal app for iOS 3.0 using Xcode 4.3.x - NSKeyedUnarchiver Exception

But since it's 2 years old an I use xcode6.1 it doesn't work.

Answer 1

The Universial Storyboard introduced in iOS8 works for iPhone and iPad 8 and for iPad 7 but not for iPhone 7 (only if not creating any iPad size layouts)

i solved the problem by using plist-keys Main sroryboard file base name (iPhone) and Main sroryboard file base name (iPad) referencing diffrent Storyboards and the iPhone one referencing the default to avoid any other trouble
