change it to this:

    FIRAuth.auth()?.signInAnonymously(completion: { (anonymousUser, error) in

        if error == nil{
            print("UserId : \(anonymousUser?.uid)")
        }else{
            print(error?.localizedDescription)
        }

    })

Note: You could change your if statement to something like:

    FIRAuth.auth()?.signInAnonymously(completion: { (anonymousUser, error) in

        if let err = error{
            print(err.localizedDescription)
            return
        }

        print("UserId : \(anonymousUser?.uid)")

    })

To save you an else and make your code more readable.
