TapGestureRecognizer Invocation Order Differs Across Platforms (iOS/macOS vs Android/Windows)

[TamilarasanGunasekaran]

I've encountered what appears to be a platform-specific inconsistency in .NET MAUI regarding TapGestureRecognizer event propagation.

I have created two custom controls (CustomControl and CustomLayout) in nested control structure where a CustomLayout is a child of a CustomControl. Both the parent (CustomControl) and the child (CustomLayout) have their own TapGestureRecognizer.

Behavior Observed:

• On Android and Windows:
  • When tapping on the layout, the child's tap gesture is invoked first, followed by the parent's.
  • This is the expected and correct behavior.
• On iOS and macOS:
  • When tapping on the layout, the parent's tap gesture is invoked first, followed by the child's.
  • This seems to be an unexpected behavior and breaks consistency across platforms.

Questions:

1. Is this a known limitation in the framework for iOS/macOS where the parent’s tap gesture is triggered before the child’s tap gesture?
2. Is there any recommended workaround to ensure consistent gesture invocation order across all platforms?

Any guidance or suggestions would be greatly appreciated!
