Firebase push notification not showing on ios10

Question

I'm using Xcode 7 and developing an app with push notification. However, I found out that all push notifications cannot be shown on iOS 10 devices. Is there any solution to fix it?

P.S. push notification is working fine on iOS 9.

Answer 1

Update to Xcode 8 is compulsory~ Otherwise, push notification would not work on iOS 10
