iOS17 scroll indicators missing

[wutschel]

When building with Xcode 15 or Xcode 14.3.1 the scroll indicator for UITableView is visible on iOS 15 simulator, but not on iOS 17. The indicator is enabled in xib, and also enabling explicitly via [dataList setShowsVerticalScrollIndicator:YES] shows no effect. The indicator inset (same as the UITableVIew inset) and style is correct.

Was there any API change? I am not finding hints on stackoverflow.

For UICollectionView (grid view) and UIScrollview (e.g. the movie details) this still works.

@kambala-decapitator, can you look into this and guide me?

also not aware of any changes in this area. Same behavior on device? Can test on the following devices:

• iOS: 12, 17
• iPadOS: 15, 17

At least it is same on my iPhone with iOS 17.3.1. I have no access to devices with older iOS versions.

Issue is gone when I comment dataList.tableHeaderView = self.searchController.searchBar; I am not clear on side effects yet.

Side effects are visible in the library list views where now the list start is hidden behind the search bar.

A workaround is:

UIView *myView = [[UIView alloc] initWithFrame:self.searchController.searchBar.frame];
dataList.tableHeaderView = myView;

This keeps the layout correct and also the indicators are back. Looks like iOS17 has a problem with tableHeaderView being a search bar.

After more testing I found an issue with the workaorund: The layout/inset is only correct for list which are longer than the view's height. As soon as there are shorter lists shown the tableHeaderView is always kept visible even though the insets tell different. I did not find a way to resolve this. So I hope for a fix in iOS.
