i added Push Extension Service (target) to my project iOS 10 Rich Notifications Integration
It can't connect to process (and it doesn't work - can't change payload). Xcode only once connected to process by "Debug - Attach to process by PID or Name". Now, it waits for "Waiting for attach" status.
Xcode 9.4.1 Running device IPhone 7 Plus 11.4
Okay, i understood - Push Extension Service is activated when you got Notification with "mutable-content":1
