使用最新版本的Xcode 7.1在Swift中运行我的应用程序时出错

给出错误：预期声明“SwiftArchitect提供的修复程序有效，但我在运行代码时遇到了这个新错误

这是我的密码：

import UIKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

var window: UIWindow?

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    // ..
    return true
}
    self.window = UIWindow(frame: UIScreen.mainScreen().bounds)
    // Override point for customization after application launch.
    self.window!.backgroundColor = UIColor.yellowColor()

    let rootVC: MyViewController = MyViewController(nibName: nil, bundle: nil)
    self.window!.rootViewController = rootVC

    self.window!.makeKeyAndVisible()
    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:.
}

您是否使用了Swift迁移工具？那个函数声明是错误的

在空的Swift iOS项目中，

didFinishLaunchingWithOptions

的设置如下：

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    self.window = UIWindow(frame: UIScreen.mainScreen().bounds)
    // Override point for customization after application launch.
    self.window!.backgroundColor = UIColor.yellowColor()

    let rootVC: MyViewController = MyViewController(nibName: nil, bundle: nil)
    self.window!.rootViewController = rootVC

    self.window!.makeKeyAndVisible()
    return true
}

import UIKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?


    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        // Override point for customization after application launch.

        self.window = UIWindow(frame: UIScreen.mainScreen().bounds)
        // Override point for customization after application launch.
        self.window!.backgroundColor = UIColor.yellowColor()

        let rootVC: MyViewController = MyViewController(nibName: nil, bundle: nil)
        self.window!.rootViewController = rootVC

        self.window!.makeKeyAndVisible()
        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:.
    }


}

您的完整AppDelegate应如下所示：

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    self.window = UIWindow(frame: UIScreen.mainScreen().bounds)
    // Override point for customization after application launch.
    self.window!.backgroundColor = UIColor.yellowColor()

    let rootVC: MyViewController = MyViewController(nibName: nil, bundle: nil)
    self.window!.rootViewController = rootVC

    self.window!.makeKeyAndVisible()
    return true
}

import UIKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?


    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        // Override point for customization after application launch.

        self.window = UIWindow(frame: UIScreen.mainScreen().bounds)
        // Override point for customization after application launch.
        self.window!.backgroundColor = UIColor.yellowColor()

        let rootVC: MyViewController = MyViewController(nibName: nil, bundle: nil)
        self.window!.rootViewController = rootVC

        self.window!.makeKeyAndVisible()
        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:.
    }


}

选项1

重新开始

Xcode>文件>新建>项目。。。

选项2

自动清理

Xcode>文件>编辑>转换>为最新的Swift语法。。。

选项3

一切都是手工做的

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    // Override point for customization after application launch.
    return true
}

也许您想强调一下Swift迁移工具，因为这段代码显然不是用Xcode 7.1创建的，它是有效的！但是，当我清理构建并再次运行代码时，它给了我一个新的错误：“预期声明”现在怎么办？@ArmaniRouse可以编辑您的问题并发布导致该错误的完整代码？对不起，我是新来的programming@JAL下面是给出新错误的代码行：self.window=UIWindow（frame:UIScreen.mainScreen（）.bounds）
