如何限制SwiftUI可拖拽元素沿圆弧移动且避免跨边跳转？

我正尝试实现一个可沿圆弧拖拽的圆形手柄，拖拽范围限定在13度到272度的圆弧区间内，效果类似滑块但沿部分圆弧轨迹。要求手柄到达圆弧端点时停止移动，而非突然跳转到另一侧继续滑动。

以下是演示该问题的SwiftUI View代码：

struct DraggableCircleView: View {
    @State private var angle: Double = 13 // 初始角度13度

    private let minAngle: Double = 13
    private let maxAngle: Double = 272
    private let size: CGFloat = 300
    private let handleSize: CGFloat = 20

    var body: some View {
        ZStack {
            Circle()
                .stroke(lineWidth: 2)
                .foregroundColor(.gray)
                .frame(width: size, height: size)
            
            Circle()
                .frame(width: handleSize, height: handleSize)
                .foregroundColor(.blue)
                .position(position(for: angle, in: CGRect(x: 0, y: 0, width: size, height: size)))
                .gesture(DragGesture()
                    .onChanged { value in
                        let center = CGPoint(x: size / 2, y: size / 2)
                        let newLocation = CGPoint(x: center.x + value.translation.width, y: center.y + value.translation.height)
                        let newAngle = angle(from: newLocation, center: center)
                        if newAngle >= minAngle && newAngle <= maxAngle {
                            self.angle = newAngle
                        } else if newAngle < minAngle {
                            self.angle = minAngle
                        } else if newAngle > maxAngle {
                            self.angle = maxAngle
                        }
                    }
                )
        }
    }

    func angle(from location: CGPoint, center: CGPoint) -> Double {
        let dx = location.x - center.x
        let dy = location.y - center.y
        let radians = atan2(dy, dx)
        let degrees = radians * 180 / .pi
        let adjustedDegrees = degrees < 0 ? degrees + 360 : degrees
        return adjustedDegrees
    }

    func position(for angle: Double, in rect: CGRect) -> CGPoint {
        let radius = Double(min(rect.width, rect.height) / 2 - handleSize / 2)
        let center = CGPoint(x: rect.midX, y: rect.midY)
        let radians = angle * .pi / 180
        return CGPoint(
            x: center.x + CGFloat(radius * cos(radians)),
            y: center.y + CGFloat(radius * sin(radians))
        )
    }
}

我认为需要在角度被限制（比如设置self.angle为minAngle或maxAngle时）中断DragGesture，但尚未找到通过代码中断拖拽手势的示例。
