I have set the placeholder runtime attributes as given in the image.
It works perfectly in iOS 8+ and crashes in iOS 7 with the following issue:
Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<UITextView 0x14bd4800> valueForUndefinedKey:]: this class is not key value coding-compliant for the key _placeholderLabel.
Can anyone help me identify the issue?
