Getting device orientation in Swift

Question

I was wondering how I can get the current device orientation in Swift? I know there are examples for Objective-C, however I haven't been able to get it working in Swift.

I am trying to get the device orientation and put that into an if statement.

This is the line that I am having the most issues with:

[[UIApplication sharedApplication] statusBarOrientation]

Answer 1

you can use:

override func didRotateFromInterfaceOrientation(fromInterfaceOrientation: UIInterfaceOrientation) {
    var text=""
    switch UIDevice.currentDevice().orientation{
    case .Portrait:
        text="Portrait"
    case .PortraitUpsideDown:
        text="PortraitUpsideDown"
    case .LandscapeLeft:
        text="LandscapeLeft"
    case .LandscapeRight:
        text="LandscapeRight"
    default:
        text="Another"
    }
    NSLog("You have moved: \(text)")        
}

SWIFT 3 UPDATE

override func didRotate(from fromInterfaceOrientation: UIInterfaceOrientation) {
    var text=""
    switch UIDevice.current.orientation{
    case .portrait:
        text="Portrait"
    case .portraitUpsideDown:
        text="PortraitUpsideDown"
    case .landscapeLeft:
        text="LandscapeLeft"
    case .landscapeRight:
        text="LandscapeRight"
    default:
        text="Another"
    }
    NSLog("You have moved: \(text)")        
}

or

override func willRotateToInterfaceOrientation(toInterfaceOrientation: UIInterfaceOrientation, duration: NSTimeInterval) {
}

with Notification you can check: IOS8 Swift: How to detect orientation change?

NOTE : didRotateFromInterfaceOrientation is Deprecated Use viewWillTransitionToSize for iOS 2.0 and later

In case of Face up and Face Down this will not work. So we need to use the following.

if UIApplication.shared.statusBarOrientation.isLandscape {
     // activate landscape changes
} else {
     // activate portrait changes
}
