如何在SwiftUI中删除文本视图上方和下方的空格？

import SwiftUI

struct ContentView: View {
    var body: some View {
        Text("Hello, World!")
            .padding(.all, 0) // 删除所有方向的padding
            .background(Color.green) // 仅用于可视化padding效果
    }
}

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

import SwiftUI

struct ContentView: View {
    var body: some View {
        Text("Hello, World!")
            .frame(maxWidth: .infinity, maxHeight: .infinity, alignment: .center)
            .background(Color.green) // 仅用于可视化padding效果
    }
}

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

import SwiftUI

struct ContentView: View {
    var body: some View {
        Text("Hello, World!")
            .frame(minHeight: 0, maxHeight: .infinity)
            .background(Color.green) // 仅用于可视化padding效果
    }
}

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