Answer 1

For anyone doing this on iOS8, this is what I had to do:

I have a swift class file titled SettingsView.swift and a .xib file named SettingsView.xib. I run this in MasterViewController.swift (or any view controller really to open a second view controller)

@IBAction func openSettings(sender: AnyObject) {
        var mySettings: SettingsView = SettingsView(nibName: "SettingsView", bundle: nil) /<--- Notice this "nibName" 
        var modalStyle: UIModalTransitionStyle = UIModalTransitionStyle.CoverVertical
        mySettings.modalTransitionStyle = modalStyle
        self.presentViewController(mySettings, animated: true, completion: nil)

    }
