The | operator should already work with UIInterfaceOrientationMask and anything
else declared with NS_OPTIONS in Objective-C headers. It would look like this
if -supportedInterfaceOrientations returned UIInterfaceOrientationMask:
override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask {
return UIInterfaceOrientationMask.Portrait |
UIInterfaceOrientationMask.PortraitUpsideDown
}
…which is perfectly fine.
