我正在尝试在SwiftUI中绘制饼图/圆环图。曲线球是它需要有圆角。

我成功地用弧线和尖角完成了它，就像这样：

struct PieSliceData {
    var startAngle: Angle
    var endAngle: Angle
    var color: Color
}

struct PieSliceView: View {
    var pieSliceData: PieSliceData
    
    var body: some View {
        GeometryReader { geometry in
            ZStack {
                Path { path in
                    let width: CGFloat = min(geometry.size.width, geometry.size.height)
                    let height = width
                    
                    let center = CGPoint(x: width * 0.5, y: height * 0.5)
                    
                    path.move(to: center)
                    
                    path.addArc(
                        center: center,
                        radius: width * 0.5,
                        startAngle: Angle(degrees: -90.0) + pieSliceData.startAngle,
                        endAngle: Angle(degrees: -90.0) + pieSliceData.endAngle,
                        clockwise: false)
                }
                .fill(pieSliceData.color)
                
            }
        }
        .aspectRatio(1, contentMode: .fit)
    }
    
}

但似乎我需要用圆弧法画出路径，才能让拐角变圆？
我不知道该怎么做...
谢谢
