SwiftUI List initializers how it is implemented? - list

Question

I can do something like this to resemble my CustomList to native SwiftUI List
But I think this approach is not very efficient and the way SwiftUI does it underneath its List component.
// MARK: - Properties
private let items: [AnyView]
public init<Data, RowContent>(onReorder: #escaping (Int, Int) -> Void = { _,_ in }, onDelete: ((Int) -> Bool)? = nil, _ data: Data, #ViewBuilder rowContent: #escaping (Data.Element) -> RowContent) where Data : RandomAccessCollection, RowContent : View, Data.Element : Identifiable {
var items = [AnyView]()
data.forEach { element in
let item = rowContent(element)
items.append(AnyView(item))
}
self.items = items
}
public init<Data, ID, RowContent>(onReorder: #escaping (Int, Int) -> Void = { _,_ in }, onDelete: ((Int) -> Bool)? = nil, _ data: Data, id: KeyPath<Data.Element, ID>, #ViewBuilder rowContent: #escaping (Data.Element) -> RowContent) where Data : RandomAccessCollection, ID : Hashable, RowContent : View {
var items = [AnyView]()
data.forEach { element in
let item = rowContent(element)
items.append(AnyView(item))
}
self.items = items
}
public init<RowContent>(onReorder: #escaping (Int, Int) -> Void = {_,_ in }, onDelete: ((Int) -> Bool)? = nil, _ data: Range<Int>, #ViewBuilder rowContent: #escaping (Int) -> RowContent) where RowContent : View {
var items = [AnyView]()
data.forEach { element in
let item = rowContent(element)
items.append(AnyView(item))
}
self.items = items
}
How I can make this all this init store something like this in properties
private let items: Data // where Data : RandomAccessCollection
private let rowContent: (Data.Element) -> Content
and make all init Data including RandomAccessCollection conform to this
I have tries many ways to achieve this but doesn't know how to do this.
I want to generate view like this
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "HostingCell") as! HostingTableViewCell
let item = parent.items[indexPath.row]
let rootView = parent.rowContent(item)
cell.host(rootView: rootView)
return cell
}
