我是编程新手，正在尝试制作应用程序。我现在的问题是，当我启动模拟器时，应用程序不显示，只有黑色和顶部的电池/时间行。我尝试过重新设置模拟器，清理程序以及其他对话中的许多其他内容，但没有任何成效。可能是什么问题呢？模拟器变成黑色
我可以插入你需要的编码线。
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()

你需要什么代码？ –
你的初始视图控制器应该是一个好开始，加上你可能在'storyboard' /'xib'中完成的任何配置 – Losiowaty
