Yes please release the code, I was able to follow the concepts just fine, implementation wise not really since most of the code was collapsed or not visible. I would really like to see how to implement this with core data

Ok I was able to come up with a solution, however becase of my limited knowledge with generics I ended up using AnyView instead of the actual data type which takes a hit on performance. import SwiftUI import PlaygroundSupport protocol DataSourceView {     associatedtype Data     associatedtype Container: View     static func make<Content: View>(@ViewBuilder content: @escaping (Data) -> Content) -> Container } struct SimpleData: Hashable {     let title: String } struct ListView<DataSource: DataSourceView>: View where DataSource.Data == [SimpleData] {     var body: some View {         DataSource.make { items in             List {                 ForEach(items, id: \.self) { item in                     Text(item.title)                 }             }         }     } } struct RichDataSource: DataSourceView {     static func make<Content: View>(content: @escaping ([SimpleData]) -> Content) -> AnyView  {         AnyView(Container(content: content))     }     struct Container<Content: View>: View {         let content: ([SimpleData]) -> Content         @State private var richDataItems = (1...10).map { $0 }         var body: some View {             content(richDataItems.map { SimpleData(title: "Title: \($0)") })         }     } } PlaygroundPage.current.setLiveView(ListView<RichDataSource>()) The following won't work which kind of what I would like to do. If anyone has a solution for this could you please provide an explanation, I would really appreciate it, again I have limited generics knowledge. static func make<Content: View>(content: @escaping ([SimpleData]) -> Content) -> Container<Content>  {         Container(content: content) }
