Whenever I try to make a call to text fields first responder, my app will crash and provide the following exception:Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Cannot get value with size 16. The type encoded as {CGRect={CGPoint=dd}{CGSize=dd}} is expected to be 32 bytes'Does anyone know where this could be derving from? I have tried removing the delegate and changing the origin of the text field, but for some reason it isn't working.
