swift protocol, IBOutlet property cannot have non-object type

Question

I would like to wire up a custom swift delegate in IB. The delegate is an object that implements a certain protocol in swift.

Answer 1

IBOutlets are to indicate a pointer to an object stored in a nib (or storyboard) file. A protocol is not an object, therefore you can't have one in a nib file. Make the type of the IBOutlet var to be the type of the actual object you have in the nib.
