I have the same problem with Xcode Version 16.2 (16C5032a) and none of the proposed solutions works. I solved it by simply adding a line to the path going from top to bottom: just after the segments.forEach loop:

                path.move(
                    to: CGPoint(
                        x: width * 0.5 + xOffset,
                        y: 0                        )
                )
                path.addLine(
                    to: CGPoint(
                        x: width * 0.5 + xOffset,
                        y: height
                    )
                )
