The log returns this at line 27:

The relevant UICollectionViewFlowLayout instance is <FullyHorizontalFlowLayout: 0x7f827acdcbc0>, and it is attached to <UICollectionView: 0x7f827b08c000; frame = (0 0; 414 93); clipsToBounds = YES; gestureRecognizers = <NSArray: 0x7f827acc9130>; layer = <CALayer: 0x7f827acc86a0>; contentOffset: {0, 0}; contentSize: {0, 93}> collection view layout: <FullyHorizontalFlowLayout: 0x7f827acdcbc0>.

This solved my problem. I don't know why but (int)(self.collectionView.frame.size.height / self.itemSize.height) returns zero.
