Updated extension provided by Andre which works with Swift 4.2:

import UIKit

    var imageOrientation: UIImage.Orientation {
        switch self {
        case .portrait, .faceUp:                return .right
        case .portraitUpsideDown, .faceDown:    return .left
        case .landscapeLeft:                    return .up
        case .landscapeRight:                   return .down
        case .unknown:                          return .up
        }
    }
