水平(或在网格中)而不是垂直地布局多个SwiftUI预览？

import SwiftUI

struct ContentView: View {
    var body: some View {
        HStack(spacing: 20) {
            PreviewView(color: .red)
            PreviewView(color: .green)
            PreviewView(color: .blue)
        }
    }
}

struct PreviewView: View {
    var color: Color
    
    var body: some View {
        Rectangle()
            .foregroundColor(color)
            .frame(width: 100, height: 100)
    }
}

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