如何在iPad上更改SwiftUI拆分视图中的主控视图宽度

import SwiftUI

struct ContentView: View {
    @State private var splitViewWidth: CGFloat = UIScreen.main.bounds.width * 0.3 // 设置初始宽度
    
    var body: some View {
        NavigationView {
            SplitView(splitViewWidth: $splitViewWidth) {
                // 主控视图
                Text("主控视图")
                    .frame(maxWidth: .infinity, maxHeight: .infinity)
                    .background(Color.blue)
                    .foregroundColor(.white)
            } detailView: {
                // 详细视图
                Text("详细视图")
                    .frame(maxWidth: .infinity, maxHeight: .infinity)
                    .background(Color.red)
                    .foregroundColor(.white)
            }
        }
    }
}

struct SplitView<Master: View, Detail: View>: View {
    @Binding var splitViewWidth: CGFloat
    let masterView: Master
    let detailView: Detail
    
    var body: some View {
        GeometryReader { geometry in
            HSplitView {
                masterView
                    .frame(width: splitViewWidth)
                detailView
            }
            .frame(width: geometry.size.width, height: geometry.size.height)
            .gesture(DragGesture().onChanged({ value in
                splitViewWidth = value.location.x
            }))
        }
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}
