我正在构建一个带有卡片的网格，其顶部有图像视图，底部有一些文本。以下是该组件的 swift UI 代码：

struct Main: View {
    var body: some View {
        ScrollView {
            LazyVGrid(columns: .init(repeating: .init(.flexible()), count: 2)) {
                ForEach(0..<6) { _ in
                    ZStack {
                        Rectangle()
                            .foregroundColor(Color(UIColor.random))
                        VStack {
                            Rectangle()
                                .frame(minHeight: 72)
                            Text(ipsum)
                                .fixedSize(horizontal: false, vertical: true)
                                .padding()
                        }
                    }.clipShape(RoundedRectangle(cornerRadius: 10))
                }
            }.padding()
        }.frame(width: 400, height: 600)
    }
}

该组件输出以下布局：

这看起来很棒，但我想在卡片组件中添加一个几何读取器，以便根据封闭网格列的宽度缩放顶部图像视图。据我所知，该代码应该如下所示：

struct Main: View {
    var body: some View {
        ScrollView {
            LazyVGrid(columns: .init(repeating: .init(.flexible()), count: 2)) {
                ForEach(0..<6) { _ in
                    ZStack {
                        Rectangle()
                            .foregroundColor(Color(UIColor.random))
                        VStack { …

将steam postgresql连接器添加到Package.swift后出现构建错误
