title: How to fix a "403 - disallowed_useragent" with the native Google Drive iOS SDK?
body: <p>I'm following the instructions given at: <a href="https://developers.google.com/drive/ios/quickstart?ver=swift" rel="noreferrer">https://developers.google.com/drive/ios/quickstart?ver=swift</a>.</p>
  
  <p>Yesterday it was working but this morning it seems to always fail. The weird part is that I'm using their native SDK. I don't know why does it believe I'm using a web-view. The exact error is:</p>
  
  <blockquote>
    <p>This user-agent is not permitted to make an OAuth authorization request to Google as it is classified as an embedded user-agent (also known as a web-view). Per our policy, only browser are permitted to make authorization requests to Google. We offer several libraries and samples for native apps to perform authorization request in the browser.</p>
