       pathColor:(nonnull id<ISCIPathColor>)pathColor
          points:(nonnull float *)points
      startIndex:(int)startIndex
           count:(int)count;

Swift

func draw(with renderContext: any ISCIRenderContext2D, pathColor: any ISCIPathColor, points: UnsafeMutablePointer<Float>, start startIndex: Int32, count: Int32)

Parameters
