Answer 1

this valueForKey("storyboardSegueTemplates") is UNDOCUMENTED property and UIStoryboardPresentationSegueTemplate is UNDOCUMENTED class. Beware of rejection from App Store if you are uploading application to App Store.

If you want to use this in your in-house projects, use as following

for template in (valueForKey("storyboardSegueTemplates") as? [AnyObject])! {
    if let identifier = template.valueForKey("identifier") as? String {
        print("identifier - " + identifier)
    }
    else {
        print("no identifier for \(template)")
    }
}
