Here is a demo of possible approach...(它是你的应用数据设置的简化版本，但发展的想法和方向应该很清楚)

Here is a demo of possible approach... (it is simplified version of your app data settings, but the idea and direction where to evolve should be clear)

主要思想不是在项目视图中而是在内容视图中捕获拖动，在需要时(或如果需要)将所需状态(或可计算的相关数据)传输到项目视图中.

The main idea that you capture drag not in item view but in the content view transferring needed states (or calculable dependent data) into item view when (or if) needed.

struct PlayerView: View {
    var scaled: Bool = false
    var player: Player = Player(name: "Phile", color: .green, age: 42)

    var body: some View {
        ZStack(alignment: .topLeading) {
            Rectangle().frame(width: 100, height: 100).foregroundColor(player.color).cornerRadius(15.0).scaleEffect(scaled ? 1.5 : 1)

            VStack {
                Text(player.name)
                Text("Age: (player.age)")
            }.padding([.top, .leading], 10)
        }.zIndex(scaled ? 2 : 1)
    }
}


struct ContentView: View {
    @EnvironmentObject var data: PlayerData

    @GestureState private var location: CGPoint = .zero
    @State private var highlighted: Int? = nil

    private var Content: some View {
        VStack {
            HStack {
                ForEach(0..<3) { i in
                    PlayerView(scaled: self.highlighted == i, player: self.data.players[i])
                        .background(self.rectReader(index: i))
                }
            }
            .zIndex((0..<3).contains(highlighted ?? -1) ? 2 : 1)

            HStack {
                ForEach(3..<6) { i in
                    PlayerView(scaled: self.highlighted == i, player: self.data.players[i])
                        .background(self.rectReader(index: i))
                }
            }
            .zIndex((3..<6).contains(highlighted ?? -1) ? 2 : 1)
        }
    }

    func rectReader(index: Int) -> some View {
        return GeometryReader { (geometry) -> AnyView in
            if geometry.frame(in: .global).contains(self.location) {
                DispatchQueue.main.async {
                    self.highlighted = index
                }
            }
            return AnyView(Rectangle().fill(Color.clear))
        }
    }

    var body: some View {
        Content
        .gesture(DragGesture(minimumDistance: 0, coordinateSpace: .global)
            .updating($location) { (value, state, transaction) in
                state = value.location
            }.onEnded {_ in
                self.highlighted = nil
            })
    }
}
