Create a view with your App Icon and use SwiftUI Previews to design.

import SwiftUI

struct AppIcon: View {
    @IconRelativeMetric var padding = 10 /// 10% padding
    let color: Color
    var body: some View {
        ContainerRelativeShape()
            .fill(Color.accentColor)
            .overlay(content: {
                Image(systemName: "circle.hexagongrid.fill")
                    .resizable()
                    .scaledToFit()
                    .padding(padding)
            })
    }
}

struct AppIcon_Previews: PreviewProvider {
    static var previews: some View {
        AppIcon()
            .iconStyle(.macOS)
            .frame(width: 100, height: 100, alignment: .center)
            .scenePadding()
    }
}

Call generateAppIconSet to generate the AppIconSet images

let path = try generateAppIconSet(from: AppIcon())
