Simple problem, I want a view that consists of a rounded rectangle with a red border and a clear fill. Here is some simple code. For sake of seeing the problem easier, I have removed the fill (and it appears the default fill is black).

import SwiftUI

struct ContentView: View {
    var body: some View {
        RoundedRectangle(cornerRadius: 30)
            .frame(width: 100, height: 100)
            .border(Color.red, width: 4)
    }
}

#if DEBUG
struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}
#endif

Run this code, you'll see a black filled rounded rectangle bounded by a red border. However, the border is not rounded, it is a simple rectangle.

Is this a bug, or am I missing something?

Did you try adjusting the border width? Try 6, as an example. Still no joy, you might need to use layers...

You have to use the stroke modifier. This produces a stroked rounded rect with no fill:

      RoundedRectangle(cornerRadius: 30)
        .stroke(Color.red, lineWidth: 4)
        .frame(width: 100, height: 100)

By the way, it seems you can't apply a fill and a stroke to the same shape simultaneously. So if you want a rounded rectangle with a fill color, you can create two rectangles (one for the fill and one for the stroke) and stack them on top of each other:

    ZStack {
      RoundedRectangle(cornerRadius: 30)
        .fill(Color.green)
      RoundedRectangle(cornerRadius: 30)
        .stroke(Color.red, lineWidth: 4)
    }
      .frame(width: 100, height: 100)

I'm playing with this arrangment. Turns out I don't need two RoundedRectangle shapes. It seems by default the RoundedRectangle is not filled with any color, and hence it is essentially clear.

Yes. I just wanted to mention that combining stroke and fill is not as straightforward as one might think.

Hi...

same problem here! Did you solve it? I used .fill with .border and the edges are not rounded, either:

Code Block 		RoundedRectangle(cornerRadius: 20.0, style: .circular )
							.frame(width: 50.0 , height: 50.0 )
							.border(Color.blue, width: 2 )
							.foregroundColor(Color.orange.opacity(0.2))
