uicollectionview - How can I use SwiftUI to populate content in a UICollectionViewCell

Question

Because SwiftUI has no UICollectionView-like controls,so I used UIKit instead.

According to interfacing-with-uikit, I know how SwiftUI interacts with UIKit, but I want to further use SwiftUI to encapsulate UICollectionViewCell, and use SwiftUI to fill the content of UICollectionViewCell, how can I do that.

As far as I know List in SwiftUI are encapsulated according to UITableView, I want SwiftUI to do the same with UICollectionView,I don't want to use some tripartite libraries to do this, I want to learn the secrets

Assuming you have CellContentView SwiftUI view, you can integrate it in UICollectionViewCell using something like the following

if let cellContent = UIHostingController(rootView: CellContentView()).view {
    cell.contentView.addSubview(cellContent)

    cellContent.leadingAnchor.constraint(equalTo: cell.leadingAnchor).isActive = true
    cellContent.trailingAnchor.constraint(equalTo: cell.trailingAnchor).isActive = true
    cellContent.topAnchor.constraint(equalTo: cell.topAnchor).isActive = true
    cellContent.bottomAnchor.constraint(equalTo: cell.bottomAnchor).isActive = true
}
