原文：https://iosdevcenters.blogspot.com/2019/09/swiftui-background-color-in-view.html

import SwiftUI

struct ContentView: View {
    var body: some View {
        Color.purple.edgesIgnoringSafeArea(.all)
    }
}

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

效果如图：
