Okay, I know that there are many question about it, but they are all from many time ago.

So. I know that it is possible because the Map app does it.

    In Swift 3 all I needed is this (here for example redirect to my app notifications): 

    if let url = URL(string: "App-Prefs:root=NOTIFICATIONS_ID&path=your app bundleID") {
    if #available(iOS 10.0, *) {
        UIApplication.shared.open(url, completionHandler: .none)
    } else {
        // Fallback on earlier versions
    }
}

    Source: phynet gist.

    This worked with me only when settings is in background. It will redirect you to your app notification settings but if settings wasn't running in the background it will just redirect you to notification settings in general.

    Add this to your class,

     public class func showSettingsAlert(title:String,message:String,onVC viewController:UIViewController,onCancel:(()->())?){
            YourClass.show2ButtonsAlert(onVC: viewController, title: title, message: message, button1Title: "Settings", button2Title: "Cancel", onButton1Click: {
                if let settingsURL = NSURL(string: UIApplicationOpenSettingsURLString){
                    UIApplication.sharedApplication().openURL(settingsURL)
                }
                }, onButton2Click: {
                    onCancel?()
            })
        }

 public class func show2ButtonsAlert(onVC viewController:UIViewController,title:String,message:String,button1Title:String,button2Title:String,onButton1Click:(()->())?,onButton2Click:(()->())?){
            dispatch_async(dispatch_get_main_queue()) {
                let alert : UIAlertController = UIAlertController(title: title, message: message, preferredStyle: UIAlertControllerStyle.Alert)

                alert.addAction(UIAlertAction(title: button1Title, style:.Default, handler: { (action:UIAlertAction) in
                    onButton1Click?()
                }))

                alert.addAction(UIAlertAction(title: button2Title, style:.Default, handler: { (action:UIAlertAction) in
                    onButton2Click?()
                }))

                viewController.presentViewController(alert, animated: true, completion: nil)
            }
        }

    Call like this,

    YourClass.showSettingsAlert("App would like to access camera", message: "App would like to access camera desc", onVC: fromViewController, onCancel: {
  print("canceled")
})

    You can use this on iOS 5.0 and later: This no longer works.

    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs://"]];

    Swift 3:

    guard let url = URL(string: UIApplicationOpenSettingsURLString) else {return}
if #available(iOS 10.0, *) {
  UIApplication.shared.open(url, options: [:], completionHandler: nil)
} else {
  // Fallback on earlier versions
  UIApplication.shared.openURL(url)
}

    Swift 4

    I prefer to open setting in a safer way,

    if let settingUrl = URL(string:UIApplicationOpenSettingsURLString) {

    UIApplication.shared.open(settingUrl)
}
else {
    print("Setting URL invalid")
}

    Seems like you can use the prefs:<area> URL to open the settings and go to specific areas. Apple could change these and break your app so always check if you can open them first.

    From this article they have listed some of them for iOS 13.1:
