尝试在swiftui中给边框一个角半径

import SwiftUI

struct ContentView: View {
    var body: some View {
        Text("Hello, World!")
            .padding()
            .border(Color.black, width: 1)
            .cornerRadius(10) // 设置角半径为10
    }
}

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