Custom strokeStyle lineCap with corner radius [duplicate]

Question

I want to be able to give these ends a corner radius of 5 instead of sharp square ends. lineCap only supports .round, .butt and .square

How can I create a custom corner radius for the lineCap?

Here is the code:

Circle()
    .trim(from: CGFloat(start + offset), to: CGFloat(end - offset))
    .stroke(
        color,
             style: StrokeStyle(
                lineWidth: ringWidth,
                lineCap: .square ,
             )
    )

If you want to keep using Circle().stroke() but just want smoother corners, you can overlay small circles at the endpoints:

ZStack {
    Circle()
        .trim(from: CGFloat(start + offset), to: CGFloat(end - offset))
        .stroke(color, style: StrokeStyle(lineWidth: ringWidth, lineCap: .butt))
    
    // Add rounded caps manually
    Circle()
        .fill(color)
        .frame(width: ringWidth, height: ringWidth)
        .offset(x: /* calculate position for start */)
    
    Circle()
        .fill(color)
        .frame(width: ringWidth, height: ringWidth)
        .offset(x: /* calculate position for end */)
}
