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
Refer the blow. It is a bug in Xcode 7 and still has not been fixed.

It can overcome by programatically setting the text property for UITextView.
