It would be very helpful if you could test the resulting artifacts from this PR and let us know in a comment whether this change resolves your issue. Thank you!

This pull request addresses a memory leak in CarouselViewController2 on iOS/MacCatalyst caused by improper cleanup of the orientation change observer. The fix ensures that the observer token is stored and properly removed, preventing the controller from being retained after navigation. A new regression test is also added to verify the fix.

Description of Change

Bug fix: Proper observer cleanup in CarouselViewController2

  • Store the observer token returned by NSNotificationCenter.AddObserver in the _orientationObserver field, allowing for correct removal later. [1] [2]
  • Update the TearDown method to remove the observer using the stored token, ensuring the block-based observer is properly cleaned up and preventing memory leaks.

Testing: Regression test for memory leak

  • Add a new test, CarouselViewController2ControllerDoesNotLeakAfterNavigationPop, to confirm that CarouselViewController2 and related objects are garbage collected after navigation, verifying the observer is correctly removed and the leak is resolved.

🤖 Automated review — alternative fix proposed

The expert-reviewer evaluation compared the PR fix against #1 automatically generated candidates and selected try-fix-1 as the strongest fix.

Why: try-fix-1 eliminates the leak structurally by removing the NSNotificationCenter orientation observer entirely and overriding UIKit's ViewWillTransitionToSize instead. Net-smaller diff than the PR, no Setup/TearDown symmetry burden, and as a free side effect closes the MacCatalyst/iPad-multitasking window-resize coverage gap that all observer-based candidates (including the PR) leave unfixed. The PR's regression test is preserved unchanged.

Please consider applying the candidate diff below (or use it as guidance). Once you push an update, this workflow will re-trigger and re-evaluate.

🤖 Automated review — alternative fix proposed

The expert-reviewer evaluation compared the PR fix against #2 automatically generated candidates and selected try-fix-2 as the strongest fix.

Why: try-fix-2 replaces the NSNotificationCenter.OrientationDidChangeNotification subscription with a UIViewController.ViewWillTransitionToSize override. This structurally eliminates the leak class (no observer to track), is the smallest diff of any candidate, fixes two latent bugs the PR leaves in place (MacCatalyst window resize and iPad split-view/Stage Manager -- OrientationDidChangeNotification never fires there because MAUI's Items2 path doesn't call BeginGeneratingDeviceOrientationNotifications), suppresses spurious face-up/face-down events, and uses Apple's recommended modern API. The PR's memory test is retained as a regression guard.

Please consider applying the candidate diff below (or use it as guidance). Once you push an update, this workflow will re-trigger and re-evaluate.

This pull request addresses a memory leak in `CarouselViewController2`
on iOS/MacCatalyst caused by improper cleanup of the orientation change
observer. The fix ensures that the observer token is stored and properly
removed, preventing the controller from being retained after navigation.
A new regression test is also added to verify the fix.
### Description of Change

**Bug fix: Proper observer cleanup in `CarouselViewController2`**
- Store the observer token returned by
`NSNotificationCenter.AddObserver` in the `_orientationObserver` field,
allowing for correct removal later.
[[1]](diffhunk://#diff-f2d56fd867f9466701484a1239e77c550c399114dacbf89da74710c420d7fc14R23)

- Update the `TearDown` method to remove the observer using the stored
token, ensuring the block-based observer is properly cleaned up and
preventing memory leaks.

**Testing: Regression test for memory leak**
- Add a new test,
`CarouselViewController2ControllerDoesNotLeakAfterNavigationPop`, to
confirm that `CarouselViewController2` and related objects are garbage
collected after navigation, verifying the observer is correctly removed
and the leak is resolved.

This pull request addresses a memory leak in `CarouselViewController2`
on iOS/MacCatalyst caused by improper cleanup of the orientation change
observer. The fix ensures that the observer token is stored and properly
removed, preventing the controller from being retained after navigation.
A new regression test is also added to verify the fix.
### Description of Change

**Bug fix: Proper observer cleanup in `CarouselViewController2`**
- Store the observer token returned by
`NSNotificationCenter.AddObserver` in the `_orientationObserver` field,
allowing for correct removal later.
[[1]](diffhunk://#diff-f2d56fd867f9466701484a1239e77c550c399114dacbf89da74710c420d7fc14R23)

- Update the `TearDown` method to remove the observer using the stored
token, ensuring the block-based observer is properly cleaned up and
preventing memory leaks.

**Testing: Regression test for memory leak**
- Add a new test,
`CarouselViewController2ControllerDoesNotLeakAfterNavigationPop`, to
confirm that `CarouselViewController2` and related objects are garbage
collected after navigation, verifying the observer is correctly removed
and the leak is resolved.
