libc++abi: terminating due to uncaught exception of type NSException

The error message libc++abi: terminating due to uncaught exception of type NSException and the assertion failure message Assertion failure in -[UICollectionView _endItemAnimationsWithInvalidationContext:tentativelyForReordering:animator:collectionViewAnimator:] indicate a problem related to the use of UICollectionView in your code. This error occurs when there is incorrect behavior or assertion violations within the UIKit library during item animations.

Possible reasons and ways to resolve the issue:

  1. Incorrect Index Usage: This error might occur if you're trying to update, move, or delete collection view items using incorrect or out-of-bounds indices. Make sure that your index operations correspond correctly to your data.

  2. Conflicting Animations: If you attempt to perform simultaneous insertions, deletions, or reordering of items using UICollectionView, it can lead to conflicts and errors. Ensure that all animations are executed in the correct sequence and do not overlap.

  3. Animator or Custom Animation Issues: If you're using animators or custom animations in your code, make sure they are set up correctly and do not trigger runtime errors.

  4. Thread Safety: Your code might be causing changes to collection view items from different threads, leading to synchronization issues and errors. Ensure that all collection operations adhere to thread safety rules.

  5. UIKit Framework Bugs: In some cases, the error might be related to bugs within the UIKit framework itself. Make sure you're using the latest iOS and Xcode versions, as bugs can be fixed in newer updates.

  6. Custom Code: If you're using custom code to configure and handle the UICollectionView, ensure that your code is not causing unexpected behavior or errors within the collection view event handling methods.

To precisely identify the cause of the error, you'll need to analyze your code, especially the parts related to the usage of UICollectionView, and check for the aforementioned issues. If the error remains unclear, you can also try debugging your code step by step and inspect the state of collection view items and animations during runtime.
