Question: I have a universal application being developed in iOS8 (XCode 6.1.1). It will support all the 4 orientations (left, right, portrait & upside down).

The problem is that, although in XCode the four options for supported orientations are checked, only left, right & portrait are working properly. So, is there a bug on XCode or iOS8? My `info.plist` shows all the supported orientations, but when I run the app on simulator or on the device it doesn't 'flip' the orientation when it's upside down. (PS: it's an singleview app, it doesn't have any navigation controller).

Thanks!

Answer: 
Well, I have figured out the purpose of the the options on project configuration... Within the options you're saying "my app support these orientations" and not "my app must use these four options"... So, on iPhone you must explicity say that a particular ViewController support all orientations (the upsidedown doesn't make parte of the default orientations, for a reason that I dont know)... The code should be like this for supporting all orientations:

```
override func supportedInterfaceOrientations() -> Int{
    return Int(UIInterfaceOrientationMask.All.rawValue)
}

```
With Swift 2.1, you can simplify @Cleversou’s answer to:

```
override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask
{
  return .All
}

```

With Swift 2.3

```
override var supportedInterfaceOrientations : UIInterfaceOrientationMask {
  return .all
}

```
