Starting from iOS 9 (I used Xcode 7.0 beta 6 (7A192o)), an Objective-C app with UITextView will hang if the text view\'s text is less than 10 characters. CP
According to the release notes of Xcode 7.1.1 this should be fixed now:
Storyboards and nibs containing UITextView elements with between 1 and 11 characters no longer hang when loaded on iOS. (23264732)
