Just fixed this same issue with Xcode 8. Preparing an iOS10 compatible build, updated to recommended Swift Migration 2.3, runs perfectly on iOS9 and iOS10 but crashes on iOS8.4. I reverted the changes in the code and the Main.storyboard and built the same content on the iOS8 with Xcode 7.3 fixed my issues.
