I'm using this method below in my UICollectionView to stretch/fill the cell, but it seems like it's constraining to the margins. It's stopping like 10 px shy of the edges. I basically want to set the constraints of the cell to "0" and "0" to fill the width completely and NOT constrained to the margins.
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout,
sizeForItemAt indexPath: IndexPath) -> CGSize {
let customHeight = CGFloat(116)
return CGSize(width: collectionView.frame.size.width, height: customHeight)
