ios - UICollectionView with two columns, different cell sizes and one after the other -

-

this i'm aiming for:

enter image description here

but collection view looks this:

enter image description here

theres kind of separator between different rows. don't need them resize auto layout, it's repeated pattern of 4 cells know exact size of each one.

i'm using 

  func collectionview(collectionview: uicollectionview, layout collectionviewlayout: uicollectionviewlayout, sizeforitematindexpath indexpath: nsindexpath) -> cgsize {

for size of each cell

and flow layout:

let flowlayout = uicollectionviewflowlayout()     flowlayout.scrolldirection = .vertical     flowlayout.minimumlinespacing = 10     flowlayout.minimuminteritemspacing = 5

how can approach separation?

you cannot using uicollectionviewflowlayout. have subclass uicollectionviewlayout , create own custom collection view layout.

thankfully great guys @ ray wenderlich have done tutorial on how create custom collection view layout mimicks layout of pinterest app. layout trying achieve.
