SwiftUI Keyboard Issue Inside TabView

Hello Everyone,

I am facing an issue with latest Xcode 12 release.

I have a TabView and inside that 4 Views attached. Now whenever, keyboard appears on any view SwiftUI calls onAppear of other 3 views.

However, the same code works fine in Xcode 11.7

For more information, You can refer to this links where I have provided sample code to test it.
