I tested both with vertical and horizontal scroll. Still works fine in iOS 15.2 simulator. Tested as well with iOS 15.0 simulator (Xcode 13.1). No problem either, collections scroll independantly.

A correction on the last code posted. Before adding collection as subview to the cell, one need to remove previous subviews (the already created collection) ; add the following before cell.contentView.addSubview(collectionView)                                                                                                               for v in cell.contentView.subviews { v.removeFromSuperview()  }

I tested on iOS 15.2, no issue. Tested also with higher CollectionViews, exceeding the height of tableView cell. No issue either.

I sent you a mail at p…t @ g m a i l .c o m . I send again. Check in your spam.

Please use the address I sent by mail to move more rapidly to the solution. It seems you have not set constraints for the collectionView respective to the safe area: leading and trailing at least. Cell is 309 wide where collection is 404. You could get them less different. You do not show either what is the image aspect.

Great. Don't forget to close this one.

What do you get when you run ? Could you show screen shot (please don't forget to edit the capture in Preview app and divide size by 2 or 3 (Adjust size in Tools menu). You have probably a problem with the constraints, but I would need to see them all to confirm what it is. Also check you have defined constraints for UIImage (leading and trailing and top to zero, bottom typically 50 or 60 to leave room for labels.     In storyboard it looks like you have drawn, not according to constraints. If you ask for menu command : Editor > Resolve Auto Layout Issues > Update frames, you may get a different display.

@G.U.T.explorer "discovered the nested for-loops execute over 1.5E14 times": that's effectively a lot and we may not have the patience to wait till year 3800 😉. But what loop do you refer to ? In which code precisely ?

So, why don't you call _filterTracks(str: "") in searchFieldDidEndSearching ?

When I open thins link (from Mac), as well as from de/app/, I get the icon and all images. I cannot test on AppStore, as app is probably not available in my country.

Thanks. So not a bug, but different from UIKit.

Which Xcode 13 ? There may be issues with 13.0

Exact. The only time I used was when I started learning Swift, following this series of courses, including one with array binding. h t t p s : / / w w w.youtube.com/watch?v=vOaXyOGL3bw.    But never used in app. Once again, take it as a personal choice.
