title: Parse signup error with swift 2 (xcode 7 beta 5)
body: <p>I am using Parse and I have a signup page where I call:</p>
  
  <pre><code>user.signUpInBackgroundWithBlock { (succeeded: Bool, error: NSError?) -&gt; Void in
  </code></pre>
  
  <p>I checked and this works on previous versions of Xcode, however there was a similar problem when Swift 1.2 came out, though it doesn't solve my problem.</p>
  
  <p>The error I get is:</p>
  
  <pre><code>Cannot invoke 'signupInBackgroundWithBlock' with an argument list of type: '((Bool, NSError?) -&gt; Void )'
  </code></pre>
  
  <p>I'd be grateful for any help.</p>
