<p>I have followed this tutorial:</p>

<p>correctly (or so I believe), however I get <a href="http://pastebin.com/uduLCTeK" rel="nofollow">these errors</a> on launch: </p>

<p>How can I fix this? </p>

<p>When I try and press the login button or create account button on my app I also get this error:</p>

  <p>"An error occurred when accessing the keychain".</p>
