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!
