Answer 1

Swift5

Step1: select project>info>url types>add url scheme

step2: go to the button action method and use this code

let tag = 1
        if let url = URL(string: "open://\(tag)")
        {
            self.extensionContext?.open(url, completionHandler: nil)
        }

step 3: welcome you get the control of your host app, jus add this in app delegate method

func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool
    {
        if url.scheme == "open"
        {
            switch url.host
            {
            case "1":
              let storyboard = UIStoryboard(name: "Main", bundle: nil)
                  let vc = storyboard.instantiateViewController(withIdentifier: "ViewController") as! ViewController
                  self.window?.rootViewController = vc
                  self.window?.makeKeyAndVisible()
            default:
                break
            }
        }
        return true
    }

Congrats! you open the controller.
