title: Facebook SDK in iOS 8 with Swift/Xcode beta 5 returning accessToken but no userID after update
body: <p>After updating my project and setup to iOS 8 / Swift / Xcode beta 5, the Facebook iOS SDK no longer returns a <code>userID</code> from <code>accessTokenData.userID</code> when the Facebook App is installed (it is nil). This is happening when the state changes to <code>FBSessionStateOpen</code>. <code>accessTokenData.accessToken</code> <em>does</em> returns a value, and I'm fairly sure that access token is the same as the access token that the browser returns after I try signing in when the Facebook App is deleted. Everything works fine if I sign in with the browser, same account and everything.</p>
  
  <p>Is this something that is on my end, or is it the Facebook iOS SDK not working anymore with the current status of the beta? And if so, should I ignore the issue above and continue development by only logging in through Safari, then revisit the issue when Facebook releases their official iOS 8 SDK update? I've noticed that they were putting out weekly updates, but now they have not updated for a month. </p>
