Swift 4 2  iOS 12 The open url options completionHandler   method has been updated to include a non-nil options dictionary  which as of this post only contains one possible option of type UIApplication OpenExternalURLOptionsKey  in the example    objc func openAppSpecificSettings         guard let url   URL string  UIApplication openSettingsURLString           UIApplication shared canOpenURL url  else               return           let optionsKeyDictionary    UIApplication OpenExternalURLOptionsKey rawValue   quot universalLinksOnly quot    NSNumber value  true            UIApplication shared open url  options  optionsKeyDictionary  completionHandler  nil     Explicitly constructing a URL  such as with  quot App-Prefs quot   has  AFAIK  gotten some apps rejected from the store

word of warning  the prefs root or App-Prefs root URL schemes are considered private API  Apple may reject you app if you use those  here is what you may get when submitting your app   Your app uses the  quot prefs root  quot  non-public URL scheme  which is a private entity  The use of non-public APIs is not permitted on the App Store because it can lead to a poor user experience should these APIs change  Continuing to use or conceal non-public APIs in future submissions of this app may result in the termination of your Apple Developer account  as well as removal of all associated apps from the App Store  Next Steps To resolve this issue  please revise your app to provide the associated functionality using public APIs or remove the functionality using the  quot prefs root quot  or  quot App-Prefs root quot  URL scheme  If there are no alternatives for providing the functionality your app requires  you can file an enhancement request
