【问题描述】：

我正在尝试使用 AWS Cognito 作为后端将用户身份验证功能添加到我的应用程序中。

到目前为止，每当我的应用程序尝试构建时，我都会收到此错误，并且当它指向我的两个类中的这些错误时。

AWSMobileClient 类：

func didFinishLaunching(application: UIApplication, withOptions launchOptions: [NSObject : AnyObject]?) -> Bool {
    print("didFinishLaunching:")


    let didFinishLaunching = AWSIdentityManager.defaultIdentityManager().interceptApplication(application, didFinishLaunchingWithOptions: launchOptions)

    if (!isInitialized) {
        AWSIdentityManager.defaultIdentityManager().resumeSession(completionHandler: {(_ result: AnyObject, _ error: Error) -> Void in
            print("result = \(result), error = \(error)")
        } as! (Any?, Error?) -> Void) --> ERROR ON THIS LINE <--
        isInitialized = true
    }
    return didFinishLaunching
}

AppDelegate 类：

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.
    return AWSMobileClient.sharedInstance.didFinishLaunching(application: application, withOptions: launchOptions as [NSObject : AnyObject]?) --> ERROR ON THIS LINE <--

【解决方案1】：

看起来 AWS MobileHub 示例代码尚未与 swift3 兼容——这就是我所遇到的；也许你也是？请参阅 here 以获取来自 AWS 的答案，以及使用旧版编译器设置的提示（我还没有整理...）
