How to inspect the responder chain?

Question

I\'m doing some crazy multiple documents inside a single window stuff with the document-based architecture and I\'m 95% done.

I have this two-tier document architect

Here is another version for Swift users:

func printResponderChain(_ responder: UIResponder?) {
    guard let responder = responder else { return; }

    print(responder)
    printResponderChain(responder.next)
}

Simply call it with self to print out the responder chain starting from self.

printResponderChain(self)
