SwiftUI获取多重形式的屏幕大小

import SwiftUI

struct ContentView: View {
    var body: some View {
        GeometryReader { geometry in
            VStack {
                Text("屏幕宽度: \(geometry.size.width)")
                Text("屏幕高度: \(geometry.size.height)")
                Text("安全区域顶部: \(geometry.safeAreaInsets.top)")
                Text("安全区域底部: \(geometry.safeAreaInsets.bottom)")
            }
        }
    }
}

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