Is there any way to get iPhone app notification to Mac computer?
There's currently no native way to do this, but there are a couple of ways to do this with 3rd party apps:
Notifyr ($4).  This will allow you to recieve push notifications from any app on your iOS device with your Mac.  There are some base system requirements, so thee the web page for full details.
ForwardNotifier (Free).  This requires you to jailbreak your phone but you will be able to get your push notification on macOS, Windows, and Linux.
