title: swift - App does not open from another app
body: <p>I try to open Uber app from my app. It redirects me straight to the appstore, not to the app. I would like it to open Uber app directly not via appstore app. Here is my function:</p>
  
  <pre class="lang-swift prettyprint-override"><code>func callUrl(){
      if let url = NSURL(string: "Uber://"), UIApplication.shared.canOpenURL(url as URL) {
          UIApplication.shared.open(url as URL)
      } else if let itunesUrl = NSURL(string: "https://apps.apple.com/us/app/uber/id368677368"), UIApplication.shared.canOpenURL(itunesUrl as URL) {
          UIApplication.shared.open(itunesUrl as URL)
      }
  }
  </code></pre>
