[meloalright]

import SwiftUI
import SwiftUISkia

struct ContentView: View {
    var body: some View {
        SwiftUISkia.Surface(width: 360, height: 360) {
-            SwiftUISkia.Rect(x: 10, y: 220, width: 30, height: 30, style: "fill", color: "cyan") {}
+            SwiftUISkia.Rect(x: 10, y: 220, width: 30, height: 30, style: "fill", color: "cyan")
        }
    }
}
