uicollectionview - Square CollectionView Cell Swift

I tried to make two square collectionView cells in one row. I implemented all of the necessary delegates. When the view is loaded, cells are not square but when I start scrolling, some cells are being square.

enter image description here

when I start scrolling :

enter image description here

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
   
    collectionView.delegate = self
    collectionView.dataSource = self
    
}

func collectionView(_ collectionView: UICollectionView,
                    layout collectionViewLayout: UICollectionViewLayout,
                    insetForSectionAt section: Int) -> UIEdgeInsets {

    

    return UIEdgeInsets(top: 5, left: 5, bottom: 5, right: 5)
}

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize{

    let width = (collectionView.frame.width/2)-0.5
    return CGSize(width:width , height: width)

}

Add more margin to width in layout delegate

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize{

    let width = (collectionView.frame.width/2)-10
    return CGSize(width:width , height: width)

}
