Swift and Firebase Database - Missing argument label 'andPriority' in call - swift

Question

The code below is being used to update my firebase database when a user registers in the app, it is suppose to authenticate the user in the database and also save a boolean value. I get the following error when this is implemented (see below).
#IBAction func signupPressed(_ sender: UIButton) {
Auth.auth().createUser(withEmail: emailEntryField.text!, password: passwordEntryField.text!) { (user, error) in
if error == nil {
//Show SVProgressHUD
SVProgressHUD.show()
//save User to Database
let newUserInfo : [String:Any] = ["email":self.emailEntryField.text!, "state":true]
self.ref.child("users").child(user?.user.uid).setValue(newUserInfo, withCompletionBlock: { (error, ref) in
print("New User Saved")
}
//Dismiss SVProgressHUD
SVProgressHUD.dismiss()
//move to info view controller
self.performSegue(withIdentifier: "signupToInfo", sender: self)
} else {
print("Signup Unsuccessul")
let alertController = UIAlertController(title: "Error", message: error?.localizedDescription, preferredStyle: .alert)
let defaultAction = UIAlertAction(title: "OK", style: .cancel, handler: nil)
alertController.addAction(defaultAction)
self.present(alertController, animated: true, completion: nil)
}
}
}

There is a missing ) after the block
self.ref.child("users").child(user?.user.uid).setValue(newUserInfo, withCompletionBlock: { (error, ref) in
print("New User Saved")
}
Add ) at the end, like this
self.ref.child("users").child(user?.user.uid).setValue: newUserInfo, withCompletionBlock: { (error, ref) in
print("New User Saved")
})
Hope it helps
