Facebook integration error?

So I added the Facebook SDK & done all the steps. When I went to go run the app on the simulator I ran into an error that says

'No Visible interface for FBAccessTokenData declares the selector userID'

I looked on stack overflow & was advised to clean the project, or restart it... Didn't work...

Error:

return (facebookId && facebookId.length > 0 && [facebookId isEqualToString:[[[PFFacebookUtils session] accessTokenData] userID]]);
