[Assert] Bounding path likely out of sync with its coordinate space: The view's bounds must contain the bounding rect

I get this when i expand a map view outside the bounds of a scrollview. I want to preserve it's top position when i play with the bouncing of the scrollview. So not sure if helps you but i don't think i can fix it.

"[Assert] Bounding path likely out of sync with its coordinate space: The view's bounds must contain the bounding rect. Bounding rect: {{0, 0}, {320, 487}}; coordinate space: <Spoto.SPPlaceDetailsView: 0x10962ba00; baseClass = UIScrollView; frame = (0 0; 320 487); clipsToBounds = YES; gestureRecognizers = <NSArray: 0x2828ee580>; layer = <CALayer: 0x28264a1e0>; contentOffset: {0, -0.5}; contentSize: {320, 668}; adjustedContentInset: {0, 0, 0, 0}>"

I got this error.

If that may help someone, here is the context.

Core reason was that I returned a negative size in

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize { }

Scenario was the following:

in an animation, I set the collectionView fram transform to a 0.1 scale.

so that the frame shrinks, for a zoom out effect.

But in some cases, I did recall this sizeForItem, with this transform still applying.

Consequence, as I computed the size from the frame size, I ended with negative value.

I just reset the transform to Identity somewhere, and crash disappeared.
