This extnesion allows to get UIInterfaceOrientation from UIScreen. It is useful for cases when by some reasons UIStatusBar and UIDevice.current.orientation are not available e.g. iMessage extension target in iOS 10.

UIScreen+InterfaceOrientation.swift

extension UIScreen {
    
    var orientation: UIInterfaceOrientation {
        let point = coordinateSpace.convert(CGPoint.zero, to: fixedCoordinateSpace)
        if point == CGPoint.zero {
            return .portrait
        } else if point.x != 0 && point.y != 0 {
            return .portraitUpsideDown
        } else if point.x == 0 && point.y != 0 {
            return .landscapeLeft
        } else if point.x != 0 && point.y == 0 {
            return .landscapeRight
        } else {
            return .unknown
        }
    }
    
}
