title: Login Parse Server Error code 101: Invalid Username/Password
body: <p>When I go to log a user in, I get the error message: <code>[Error]: Invalid username/password. (Code: 101, Version: 1.12.0)</code>. The user exists, is shown in Parse Dashboard, and I can sign up just fine. I've done research on this topic and I found <a href="https://stackoverflow.com/questions/30076772/parse-swift-login-error-invalid-user-credentials">this post</a>, but it doesn't appear to work both on a real device and the simulator.</p>
  
  <p>Xcode: 7.3
  iOS: 9.3</p>
  
  <p>My code is below:</p>
  
  <pre><code>  PFUser.logInWithUsernameInBackground((usernameField?.text)!, password: (passwordField?.text)!) { (user: PFUser?, error: NSError?) -&gt; Void in
              if error == nil {
                  //Segue to account
                  self.defaults.data.setValue(self.usernameField?.text, forKey: "currentUser")
  
                 self.presentViewController(AccountInterface(), animated: true, completion: {
  
                 })
              } else {
                  print(error?.description)
              }
          }
  </code></pre>
  
  <p>Thanks </p>
