How to set UIWindow property in Swift

Ive been trying to make a simple change in UIWindow bounds in Swift. So far I have:

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


    //SHIFT EVERYTHING DOWN - THEN UP IN INDIV VCs IF ios7>
    var device:UIDevice=UIDevice()
    var systemVersion:String=device.systemVersion
    println(systemVersion)
    //Float(systemVersion)

    if (systemVersion >= "7.0") {
        UIApplication.sharedApplication().setStatusBarStyle(UIStatusBarStyle.LightContent, animated: true)
        self.window.setClipsToBounds = true // --> Member doesnt exist in UIWindow
        self.window.frame = CGRectMake(0,20,self.window.frame.size.width,self.window.frame.size.height);
        self.window.bounds = CGRectMake(0,0, self.window.frame.size.width, self.window.frame.size.height);
    //}

    let ok = true
    println("Hello World")
    return true
}

but I get:

UIWindow does not have member named at each self.window.property setter line.

In the AppDelegate class, window is an optional variable. You need to force unwrap the variable with !.

For example,

self.window!.clipsToBounds = true

If you aren't familiar with how optionals in Swift work, check out documentation from Apple about them.

The problem is that self.window is an Optional. You first have to "unwrap" it. You also need to use clipsToBounds not setClipsToBounds.:

if let window = self.window {
    window.clipsToBounds = true
    window.frame = CGRect(x: 0, y: 20, width: window.frame.size.width, height: window.frame.size.height);
    window.bounds = CGRect(x: 0, y: 0, width: window.frame.size.width, height: window.frame.size.height);
}

Note: I also updated CGRectMake to the preferred Swift way of creating CGRect using the CGRect initializer instead of the global CGRectMake function.
