Hey guys/gals, I successfully compiled the first project in the book but there is not gui, its just black. if i hit the square on the bottom of the phone emulator it takes me to installed apps and quiz is there but again, no gui when i run it. help please.
i found this error but have no idea where the issue is:
‘NSInvalidUnarchiveOperationException’, reason: ‘Could not instantiate class named NSLayoutConstraint’
thanks for the help
