How to create a custom delete button without using the slide to delete that comes with swiftUI I am not using list, just using a foreach loop

Question

Since, the onDelete and onMove are features of List/form I cannot use them when I have custom interfaces without them. I have used a VStack inside a ForEach. I am quite new to swiftUI and unsure on how I can implement custom code for onDelete and onMove.

Here's my code:

struct Trying: View {
    @State private var numbers = [0,1,2,3,4,5,6,7,8,9]
    var body: some View {
        NavigationView {
            VStack (spacing: 10) {
                ForEach(numbers, id: .self) { number in
                    VStack {
                        Text("(number)")
                    }
                    .frame(width: 50, height: 50)
                    .background(Color.red)
                }.onDelete(perform: removeRows)
            }
            .navigationTitle("Trying")
            .navigationBarItems(trailing: EditButton())
        }
    }
    
    func removeRows(at offsets: IndexSet) {
        numbers.remove(atOffsets: offsets)
    }
}

The way it works right now:

Here is a simple demo of possible approach to implement custom delete (of course with move it would be more complicated due to drag/drop, but idea is the same). Tested with Xcode 12 / iOS 14.

struct DemoCustomDelete: View {
    @State private var numbers = [0,1,2,3,4,5,6,7,8,9]
    var body: some View {
        NavigationView {
            VStack (spacing: 10) {
                ForEach(numbers, id: .self) { number in
                    VStack {
                        Text("(number)")
                    }
                    .frame(width: 50, height: 50)
                    .background(Color.red)
                    .overlay(
                        DeleteButton(number: number, numbers: $numbers, onDelete: removeRows)
                    , alignment: .topTrailing)
                }.onDelete(perform: removeRows)
            }
            .navigationTitle("Trying")
            .navigationBarItems(trailing: EditButton())
        }
    }

    func removeRows(at offsets: IndexSet) {
        withAnimation {
            numbers.remove(atOffsets: offsets)
        }
    }
}

struct DeleteButton: View {
    @Environment(.editMode) var editMode

    let number: Int
    @Binding var numbers: [Int]
    let onDelete: (IndexSet) -> ()

    var body: some View {
        VStack {
            if self.editMode?.wrappedValue == .active {
                Button(action: {
                    if let index = numbers.firstIndex(of: number) {
                        self.onDelete(IndexSet(integer: index))
                    }
                }) {
                    Image(systemName: "minus.circle")
                }
                .offset(x: 10, y: -10)
            }
        }
    }
}
