ios app store rejection - Your app uses the “prefs:root=” non-public URL scheme

Question

I recently uploaded a new version of my app to itunes connect. My app got rejected with this note

Your app uses the \"prefs:root=\" non-public URL s

Answer 1

I faced the same rejection form Apple and to open app settings i was using the below code and it's not accepted on iOS11.

let url = URL(string : "prefs:root=")
if UIApplication.shared.canOpenURL(url!) {
    UIApplication.shared.openURL(url!)
 }

So, to open Settings, I used the below code and App was approved.

guard let settingsUrl = URL(string: UIApplicationOpenSettingsURLString) else {
    return
  }
  if UIApplication.shared.canOpenURL(settingsUrl)  {
    if #available(iOS 10.0, *) {
      UIApplication.shared.open(settingsUrl, completionHandler: { (success) in
      })
    }
    else  {
      UIApplication.shared.openURL(settingsUrl)
    }
  }
