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.

You can in connect your own protocols in IB with this workaround. It's a known issue with Xcode, so will probably be solved one day. Until then:

1. Declare the delegate as an AnyObject - @IBOutlet var delegate:AnyObject!
2. Connect the delegate in Interface Builder
3. Change the outlet's type to your protocol, e.g. @IBOutlet var delegate:MyDelegate

This works for me.
