How to fit full cell with an image

Question

I want cell's background to be completely filled with an image, but I am unable to do it.
I have tried all of image scalings, but none of them helped.
Code:

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let myCell = collectionView.dequeueReusableCell(withReuseIdentifier: "MyCell", for: indexPath)
    myCell.backgroundColor = .red
    let imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: myCell.frame.width , height: myCell.frame.height))
    let image = UIImage(named: "background")
    imageView.image = image
    imageView.clipsToBounds = true
    myCell.backgroundView = UIView()
    myCell.backgroundView!.addSubview(imageView)
    
    return myCell
}

And this is how it looks like:

Maybe the problem is in my imageView's frame? I think its not because I tested with changing imageView's background colour and all the cell's red colour was overlayed with blue.

You will have to use constraints here so add this extension to a file in your project.

And then instead of

myCell.backgroundView!.addSubview(imageView)

Do this

myCell.backgroundView!.embedView(imageView)
