On my first view controller I had no problem creating IBOutlets and Actions, but when I made another view controller, I couldn't make an IBOutlet. There was no blue line when I control dragged it and I couldn't make an IBOutlet and then connect it up either. The first view controller still works. Is it possible to make IBOutlets on two different view controller?
Your view controller must have a custom class file assigned to it in the identity inspector in InterfaceBuilder:
Then select the assistant editor and you should be able to ctrl-drag IBOutlets to the associated swift file.
