(lldb)AppDelegate 类看起来像这样`import UIKit
@UIApplicationMain class AppDelegate: UIResponder, UIApplicationDelegate {
@UIApplicationMain 类 AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
return true
}
func applicationWillResignActive(application: UIApplication) {
// Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
// Use this method to pause ongoing tasks, disable timers, and throttle down OpenGL ES frame rates. Games should use this method to pause the game.
}
func applicationDidEnterBackground(application: UIApplication) {
// Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
// If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
}
func applicationWillEnterForeground(application: UIApplication) {
// Called as part of the transition from the background to the inactive state; here you can undo many of the changes made on entering the background.
}
func applicationDidBecomeActive(application: UIApplication) {
// Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
}
func applicationWillTerminate(application: UIApplication) {
// Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
}
}
And the view controller looks like thisimport UIKit
}
And the view controller looks like this进口的UIKit
class ViewController: UIViewController {
类视图控制器：UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
} ` I am testing this in the simulator could this not be working because I don't have an iOS developer program?
` 我正在模拟器中测试这个，这会不会因为我没有 iOS 开发者程序而无法工作？

Looks like you have a lingering connection to a no-longer-existent outlet. Perhaps you deleted a textField that you previously set up?
看起来您与一个已不存在的插座之间存在着挥之不去的联系。也许您删除了之前设置的 textField？
Ctrl-/right-click on the File's Owner in the Xcode editor, look for a warning triangle. Clear that out (by deleting the connection or re-connecting it to the proper outlet) and you'll likely be good.
Ctrl-/右键单击 Xcode 编辑器中的 File's Owner，查找警告三角形。清除它（通过删除连接或将其重新连接到正确的插座），您可能会好起来。

There maybe another cause here: you made a Outlet and then you changed its name or add another Outlet using a new name.
这里可能还有另一个原因：您创建了一个 Outlet，然后更改了它的名称或使用新名称添加了另一个 Outlet。
You can check it by this way:
您可以通过以下方式进行检查：
click on the Label or Button element you put in the Storyboard, look at the right side bar, find "Show the connections inspector" then you can find its connection.
单击您放在 Storyboard 中的 Label 或 Button 元素，查看右侧栏，找到“显示连接检查器”，然后您可以找到它的连接。
If you just made some mistakes with the connections, it will show you here.
如果您只是在连接上犯了一些错误，它会在此处显示。
For me, I created two connections with one Outlet, that's why I kept getting the error. After I removed one of the wrong conection, it compiled successfully.
对我来说，我用一个 Outlet 创建了两个连接，这就是我不断收到错误消息的原因。在我删除了错误的连接之一后，它编译成功。

In Main.storyboardI selected my Text Field, then on the far right I have my Utilitiesshowing and selected Show the Connections inspector. There in the Referencing Outletssection I had two connections selected:
在Main.storyboard我选择了我的文本字段，然后在最右边我有我的Utilities显示并选择了Show the Connections inspector. 在该Referencing Outlets部分中，我选择了两个连接：
- a
number-View Controllerand - a
enterText-View Controller.
- 一个
number-View Controller和 - 一个
enterText-View Controller。
I simply selected the xmarker on my enterText-View Controllerto delete it (because in my case I only wanted a number selection) and that fixed this problem for my case.
我只是选择了x我的标记enterText-View Controller来删除它（因为在我的情况下我只想要一个数字选择）并且为我的情况解决了这个问题。
