Programmatic Ios App

My checklist when making a programmatic iOS app

Clean up the AppDelegate.swift class and add a Window variable:
Delete Main storyboard file base name in the info.plist (since xcode 11 also remove scenedelegate)
Now you can delete ViewController.swift and Main.storyboard (since xcode 11 also remove scenedelegate)
Add MainVC and MainView
CMD + R Run the app, if the background is orange it works

import UIKit
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
   lazy var window: UIWindow? = createWindow()
   func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
      _ = window
      return true
   }
}
extension AppDelegate {
   func createWindow() -> UIWindow {
      let win = UIWindow(frame: UIScreen.main.bounds)
      let vc = ViewController()
      win.rootViewController = vc
      win.makeKeyAndVisible() // Important since we have no Main storyboard anymore
      return win
   }
}
class ViewController: UIViewController {
   override func viewDidLoad() {
      super.viewDidLoad()
      view = View()
      view.backgroundColor = .orange
   }
   override var prefersStatusBarHidden: Bool { return false }
}
class View: UIView {
   override init(frame: CGRect) {
      super.init(frame: frame)
   }
   /**
    * Boilerplate
    */
   required init?(coder aDecoder: NSCoder) {
      fatalError("init(coder:) has not been implemented")
   }
}
