title: iOS Universal Links: Rails backend
body: <ol>
  <li><p>I have set successfully a backend server on Rails with <strong>apple-app-site-association</strong> file in the root i.e.</p>
  
  <p><a href="https://example.com/apple-app-site-association" rel="nofollow noreferrer">https://example.com/apple-app-site-association</a></p></li>
  <li><p>In iOS app the entitlements mentioned are correct i.e</p>
  
  <p>applinks:id.example.com</p></li>
  <li><p>Content of the <strong>apple-app-site-association</strong> file on server is also correct.</p></li>
  </ol>
  
  <p>But when I'm testing the universal links then it is not working.
  The content for the file contains two app domains one for staging and on for production. The universal link is working fine in production app but not in staging app</p>
