How to add a custom view after every 2 rows in a collectionView swift

I am implementing general collectionView in a viewController to populate data and the collection view has 2 columns and the number of rows depend on the data, and now my collectionView looks like this.
Normal collectionView:
This is what I have implemented in my app as you can see it is a normal collection view with n rows and 2 columns. But, our requirement is
Business requirement Image:
There is the custom view which is added after every 2 rows and it is static with a two labels and a button...
I don't know if it is possible and how to achieve this... And after searching for some time I learned that we can do this by using DecoratorViews and I don't know what are those and how to use them.. If anyone have any idea on how to achieve this kind of layout, please guide me..

You could add a header to your collectionview, or you could create a custom cell (the one that has a blue background) and incellForItemAtcheck if it is the 2nd row and return this custom cell. Also, return its size insizeForItemAt

My Code should be explanatory. I have set some values in viewdidload to get the kind of view you require.

let totalProducts = 21

// Do any additional setup after loading the view.
let quot = (totalProducts/(columnsPerRow * addAfterRows))
print(quot)
celltoShowWithAds = totalProducts + quot + 1
collectionView.register(UINib(nibName: "CollectionItemCell", bundle: nil), forCellWithReuseIdentifier: "CollectionItemCell")
collectionView.register(UINib(nibName: "CollectionAdvertisementCell", bundle: nil), forCellWithReuseIdentifier: "CollectionAdvertisementCell")

My Code should be explanatory. I have set some values in viewdidload to get the kind of view you require.
import UIKit

let totalProducts = 21
let columnsPerRow = 2
let addAfterRows = 2

override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
let quot = (totalProducts/(columnsPerRow * addAfterRows))
print(quot)
celltoShowWithAds = totalProducts + quot + 1
collectionView.register(UINib(nibName: "CollectionItemCell", bundle: nil), forCellWithReuseIdentifier: "CollectionItemCell")
collectionView.register(UINib(nibName: "CollectionAdvertisementCell", bundle: nil), forCellWithReuseIdentifier: "CollectionAdvertisementCell")
collectionView.delegate = self
collectionView.dataSource = self
collectionView.reloadData()
//collectionView.backgroundColor = UIColor.blue
}

return myCell as CollectionAdvertisementCell;
}else if indexPath.row % 5 == 0{

return myCell as CollectionAdvertisementCell;
}else{
let myCell:CollectionItemCell = collectionView.dequeueReusableCell(withReuseIdentifier: "CollectionItemCell", for: indexPath) as! CollectionItemCell
return myCell as CollectionItemCell;
}

return CGSize(width: view.frame.width, height: 80.0)
}else{
return CGSize(width: view.frame.width/CGFloat(columnsPerRow), height: 200.0)

Possible duplicate of UICollectionView Decoration View. Literally the first hit in Google when searching for DecoratorViews UICollectionView. Do your research!

You could add a header to your collectionview, or you could create a custom cell (the one that has a blue background) and in
cellForItemAtcheck if it is the 2nd row and return this custom cell. Also, return its size insizeForItemAt– Marwen Doukh
Jan 2 at 8:25
This can be an another cell itself.
