In Swift, how to get the device orientation correctly right after it's launched?

Question

I use following code to see if the device is in landscape mode or not:

UIDevice.currentDevice().orientation.isLandscape.boolValue

It works

Answer 1

I had a problem to detect which orientation was before isFlat so I put this in my view controller

let orientation = UIDevice.current.orientation

override open var supportedInterfaceOrientations: UIInterfaceOrientationMask {
    if  orientation.isPortrait {
        return .portrait
    } else if orientation.isFlat{
        if UIScreen.main.bounds.width < UIScreen.main.bounds.height{
            return .portrait
        } else {
            return .landscape
        }
    } else {
        return .landscape
    }
}
