There sure area lot more questions posted than helpful replies in these forums. No response even by Apple. I submitted a request for help and they asked for screenshots! Of what? The lack of a banner notification? Upshot of it all, if you're having this problem, move your app to Test Flight - that uses the production notification system, whereas Xcode and the simulator do not and are very low priority. After moving my app to Test Flight, I got all the notifications expected.
