How to fix a crash in SwiftUI caused by UICollectionView _validateScrollingTargetIndexPath?
问题
我正在开发一个SwiftUI应用程序。应用程序一直崩溃，并显示以下错误消息：
UIKitCore: - [UICollectionView _validateScrollingTargetIndexPath:] + 412
我已经在Xcode的Organizer > App > Reports > Crashes部分检查了崩溃日志，并发现这是问题的根源，但我不理解。
有人可以帮助我理解是什么导致了这个崩溃以及如何修复它吗？我会感激任何有关如何排除此问题的指导或建议。
提前感谢！

I'm working on a SwiftUI app. The app keeps crashing with the following error message:
UIKitCore: - [UICollectionView _validateScrollingTargetIndexPath:] + 412
I've checked the crash logs in Xcode's Organizer > App > Reports > Crashes section and found this to be the source of the problem, but I don't understand.
Can anyone help me understand what's causing this crash and how to fix it? I'd appreciate any guidance or advice on how to troubleshoot this issue.
Thanks in advance!
