Type NSError? does not conform to protocol '_RawOptionSetType'

I have the following statement:

func sessionStateChanged(session:FBSession, state:FBSessionState, error:NSError?) {
        // If the session was opened successfully
        if error == nil && state == FBSessionStateOpen {
            println("Session opened");
        }
}

which has the following error on the line of the if-statement: 

Type NSError? does not conform to protocol '_RawOptionSetType'

However if I remove the second condition, so the code reads:

if error == nil {
    println("Session opened");
}

There is no error. This leads me to believe tat the NSError? type is not the issue and that it has something to do with the multiple conditions.

One way to get clearer error messages might be to start a new if statement inside the first rather than combining with && .
