我是編程新手，正在嘗試製作應用程序。我現在的問題是，當我啓動模擬器時，應用程序不顯示，只有黑色和頂部的電池/時間行。我嘗試過重新設置模擬器，清理程序以及其他對話中的許多其他內容，但沒有任何成效。可能是什麼問題呢？模擬器變成黑色
我可以插入你需要的編碼線。
的ViewController：
import UIKit
import GoogleSignIn
import Firebase
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, GIDSignInDelegate {
func sign(_ signIn: GIDSignIn!, didDisconnectWith user: GIDGoogleUser!, withError error: Error!) {
}
func sign(_ signIn: GIDSignIn!, didSignInFor user: GIDGoogleUser!, withError error: Error!) {
}
var window: UIWindow?
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions:[NSObject: AnyObject]?) -> Bool {
FIRApp.configure()
self.window = UIWindow(frame:UIScreen.main.bounds)
let mainStoryboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
var ViewController: ViewController = mainStoryboard.instantiateViewController(withIdentifier: "ExampleController") as! ViewController
self.window?.rootViewController = ViewController
self.window?.makeKeyAndVisible()
var configureError: NSError?
GGLContext.sharedInstance().configureWithError(&configureError)
assert(configureError == nil, "Error configuring Google services: \(configureError)")
GIDSignIn.sharedInstance().clientID = "YOUR_CLIENT_ID"
GIDSignIn.sharedInstance().delegate = self
GIDSignIn.sharedInstance().clientID = FIRApp.defaultApp()?.options.clientID
// Initialize sign-in

// [START_EXCLUDE silent]
NotificationCenter.default.post(
