[SwiftUI] List Edit

• 아래 모디파이어들을 이용하려면 List가 아닌 ForEach를 사용해야 한다.
• 또한 표시되는 데이터를 State 변수화해야한다.

onDelete

struct EditMode: View {
    @State private var items = AppleProduct.sampleList
    
    var body: some View {
        VStack {
            List {
                ForEach(items) { item in
                    Text(item.name)
                }
                .onDelete { rows in
                    items.remove(atOffsets: rows)
                }
            }
        }
    }
}

onMove

struct EditMode: View {
    @State private var items = AppleProduct.sampleList
    
    var body: some View {
        VStack {
            List {
                ForEach(items) { item in
                    Text(item.name)
                }
                .onMove(perform: move)
                .onDelete { rows in
                    items.remove(atOffsets: rows)
                }
            }
        }
        .toolbar {
            EditButton()
        }
    }
    
    func move(from: IndexSet, to: Int) {
        items.move(fromOffsets: from, toOffset: to)
    }
}
