问题描述

基于Swift的应用程序是否适用于 OS X 10.9 （Mavericks）/ iOS  7和更低？

Will Swift-based applications work on OS X 10.9 (Mavericks)/iOS 7 and lower?

例如，我有一台运行的机器OS X 10.8 （Mountain Lion），我想知道我在Swift中编写的应用程序是否会运行它。

For example, I have a machine running OS X 10.8 (Mountain Lion), and I am wondering if an application I write in Swift will run on it.

推荐答案

我刚刚为你测试过，Swift应用程序编译成标准二进制文件，可以在OS X 10.9和iOS 7上运行。

I just tested it for you, Swift applications compile into standard binaries and can be run on OS X 10.9 and iOS 7.

用于测试的简单Swift应用程序：

Simple Swift application used for testing:

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {
    self.window = UIWindow(frame: UIScreen.mainScreen().bounds)

    var controller = UIViewController()
    var view = UIView(frame: CGRectMake(0, 0, 320, 568))
    view.backgroundColor = UIColor.redColor()
    controller.view = view

    var label = UILabel(frame: CGRectMake(0, 0, 200, 21))
    label.center = CGPointMake(160, 284)
    label.textAlignment = NSTextAlignment.Center
    label.text = "I'am a test label"
    controller.view.addSubview(label)

    self.window!.rootViewController = controller
    self.window!.makeKeyAndVisible()
    return true
}
