swift - The "prefs" URL Scheme is not working in iOS 10 (Beta 1 & 2)

Question

I can't get the "prefs" URL Scheme to work in iOS 10 (Beta 1).
It's set up correctly since the same App works fine on iOS 9.

Is this a bug or did it get renamed / removed?

Code:

let settingsUrl = NSURL(string: "prefs:root=SOMETHING")
if let url = settingsUrl {
    UIApplication.sharedApplication().openURL(url)
}

Update: (Beta 2)
Still not working in Beta 2.
It seams to be an bug. For example if you want do invite someone using GameCenter in iOS 10 and you're not logged into iMessage, you'll get a popup asking you to log in. But the "Settings" button does absolutely nothing.

Answer 1

Just replace prefs to App-Prefs for iOS 10

Below code works for iOS 8,9,10

Swift 3.0 and Xcode >= 8.1

if #available(iOS 10.0, *)
{
       UIApplication.shared.openURL(URL(string: "App-Prefs:root=SOMETHING")!)
}
else
{
       UIApplication.shared.openURL(URL(string: "prefs:root=SOMETHING")!)
}

Swift 2.2

if #available(iOS 10.0, *)
{
      UIApplication.sharedApplication().openURL(NSURL(string:"App-Prefs:root=SOMETHING")!)
}
else
{        
    UIApplication.sharedApplication().openURL(NSURL(string:"prefs:root=SOMETHING")!)
}

Works for me.

Happy Coding ??
