currently i am using swift 3 and storyboard, googled everything and looked over all stackoverflow similar questions, got nothing so far.
On my example Porject,
my Collection view looks like this Simulator Screenshot
which is not what i want, i want a grid layout with no spacing at all, i edited the storyboard values ddin't got anything there, so for that i used this code
let layout: UICollectionViewFlowLayout = UICollectionViewFlowLayout()
let width = UIScreen.main.bounds.width
layout.sectionInset = UIEdgeInsets(top: 0, left: 5, bottom: 0, right: 5)
layout.itemSize = CGSize(width: width / 2, height: width / 2)
layout.minimumInteritemSpacing = 0
layout.minimumLineSpacing = 0
collectionView!.collectionViewLayout = layout
didn't work either :(
