Get Ready For The Big Screen(s) Apple made a big splash this week with the new iPad Pro. In the promo videos, they've shown off using the USB-C port to connect the iPad to an external display for creative tasks. This is a feature that few people know already exists on all iOS devices. You can connect an external display via a lightning adapter or AirPlay Screen Mirroring to an Apple TV. With this small amount of code, you can listen for the connection/disconnection of displays and set up a separate window and view controller hierarchy for the external display to augment your app's main content. import UIKit class ViewController: UIViewController { // For demo purposes. We're just showing a string description // of each UIScreen object on each screen's view controller @IBOutlet var screenLabel: UILabel! static func makeFromStoryboard() - ViewController { return UIStoryboard(name: "Main", bundle: nil) .instantiateInitialViewController() as! ViewController } } @UIApplicationMain class AppDelegate: UIResponder, UIApplicationDelegate { // The main window shown on the device's display // The main storyboard will set this up automatically var window: UIWindow? // References to our windows that we're creating var windowsForScreens = [UIScreen: UIWindow]() // Create our view controller and add text to our test label private func addViewController(to window: UIWindow, text: String) { let vc = ViewController.
