I'm currently developing a game using Swift 3, SpriteKit, and Xcode 8 beta. I'm trying to implement static 3D Touch Quick Actions from the home screen through the info.plist. Currently, the actions appear fine from the home screen, but don't go to the right SKScene - goes to the initial scene or last opened scene (if app is still open) which means that the scene is not being changed. I've tried various ways of setting the scene inside the switch statement, but none seem to work properly for presenting an SKScene as the line window!.rootViewController?.present(gameViewController, animated: true, completion: nil) only works on UIViewController.
Various parts of this code are from various tutorials, but I'm fairly sure through my investigation that the broken part is the scene being presented (unless I'm wrong), because it shouldn't even load any scene if a part is broken.
Are there any ways I can present an SKScene from the AppDelegate or set the opening scene based of the switch statement?
AppDelegate

import SpriteKit
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
guard !handledShortcutItemPress(forLaunchOptions: launchOptions) else { return false } // ADD THIS LINE
return true
}
}
extension AppDelegate: ShortcutItem {
/// Perform action for shortcut item. This gets called when app is active
func application(_ application: UIApplication, performActionForShortcutItem shortcutItem: UIApplicationShortcutItem, completionHandler: (Bool) -> Void) {
completionHandler(handledShortcutItemPress(forItem: shortcutItem))
}
}
extension AppDelegate: ShortcutItemDelegate {
func shortcutItem1Pressed() {
Timer.scheduledTimer(timeInterval: 0.5, target: self, selector: #selector(loadShopScene), userInfo: nil, repeats: false)
}
@objc private func loadShopScene() {
let scene = ShopScene(size: CGSize(width: 768, height: 1024))
loadScene(scene: scene, view: window?.rootViewController?.view)
}
func shortcutItem2Pressed() {
Timer.scheduledTimer(timeInterval: 0.5, target: self, selector: #selector(loadGameScene), userInfo: nil, repeats: false)

skView.ignoresSiblingOrder = true
#if os(iOS)
