What is the "Swift Interface Summary" in Xcode 6 Jump Bars?

Question

I found that in Xcode 6 Jump Bars there are several new elements, such as the "Source" and "A Brief Description of the Swift Interface". I was confused by the "Short description of the Swift interface" , how can we use it? I could not make him active, he was always gray. Thanks!

(From the literal meaning, I think this refers to "@IBOutlet", "@IBAction", "@IBDesignable" or "@IBInspectable", but it seems useless.)

Answer 1

It should have shown the code, as would be seen by the consumer importing your target. I have never seen it work in Xcode 6.

It has been renamed "Generated Interfaces" and actually works in Xcode 7
