Ios swift – Is there any alternative method to dequeueReusableCell in SwiftUI, similar to UIKit?

I’m currently working on a SwiftUI project and encountered a scenario where I need to achieve something similar to the dequeueReusableCell method in UIKit. In UIKit, I would typically reuse cells to optimize memory usage in a UITableView or UICollectionView.

Is there an equivalent or alternative method in SwiftUI for reusing views or components in a similar manner? I’ve searched the documentation and forums but haven’t found a clear solution yet.

Here’s a simplified version of what I’m trying to achieve:

// Example in UIKit
let cell = tableView.dequeueReusableCell(withIdentifier: "MyCell", for: indexPath) as! MyCustomCell
// Do something with the cell...

// What would be the equivalent in SwiftUI?
// Is there a mechanism for reusing views efficiently?

Any guidance or examples would be greatly appreciated. Thanks in advance!

    Cell dequeueing happens automatically for any views of the same type inside SwiftUI’s List and Grid which are equivalent to UIKit’s UITableView and UICollectionView respectively

    List(arr,id:.self) { row in
   DetailListCell(.....  <<< Will be dequeued

    TableView equivalent to SwiftUI is a List. You will also have ForEach within a List to indicate a kind of cell. Simply place any View inside the ForEach content block, it’s a "cell" appearance:

    struct ContentView: View {
    var list = Array(0...100)

    var body: some View {
        NavigationStack {
            VStack {
                List {
                    ForEach(list, id: .self) {
                        Text("($0)")
                    }
                }
            }
            .navigationTitle("List here")
        }
    }
}
