Issue
When an Entity with a ViewAttachmentComponent is:
disabled using isEnabled = false
removed using removeFromParent()
and then enabled or added back again, the attached SwiftUI view is rendered correctly, but tap interactions stop working.
Specifically:
Button actions inside the attached view do not fire
TapGesture closures on child views do not respond
Expected Behavior
Tap interactions inside the attached view should continue to work after the Entity is re-enabled or re-added.
Actual Behavior
After being disabled or removed once, all tap interactions stop responding.
Comparison
When displaying the same SwiftUI view using RealityViewAttachments, this issue does not occur.
Removing and re-displaying the attachment still allows taps to work correctly.
Reproduction
Attached sample code reproduces the issue:
A RealityView with an Entity that has a ViewAttachmentComponent
The attached SwiftUI view contains a Toggle
The toggle updates isEnabled on the Entity
After toggling off and on, tap interactions stop responding
Environment
Xcode 26
visionOS 26
Question
Is this expected behavior of ViewAttachmentComponent, or a bug?
Is there a recommended way to temporarily hide or disable an Entity with ViewAttachmentComponent without breaking tap interactions?
