Hi, can you help by showing how can i connect the rounded circles? Sometimes they work like sprayed dots but i need to make then like a continuous line. Thanks

Follow below codeBlock, It will solve your problem

private var previousPoint: CGPoint?

@IBAction func gestureRecognizerUpdate(_ sender: UIGestureRecognizer) {
      let point = sender.location(in: self)
      if sender.state == .began {
          saveCurrentMaskState()
          previousPoint = point 
      } else if sender.state == .ended || sender.state == .cancelled {
          previousPoint = nil 
      }

      if sender.state == .changed {
          if let previousPoint = previousPoint {
              drawLineFromPoint(from: previousPoint, to: point) // Draw a line between points
          }
          previousPoint = point 
      } else {
          shapeLayer.path = nil
          outerShapeLayer.path = nil
      }
  }

private func drawLineFromPoint(from startPoint: CGPoint, to endPoint: CGPoint) {
      guard let renderer = renderer else { return }

      let image = renderer.image { context in
          if let maskImage = maskImage {
              maskImage.draw(in: bounds)

              let path = UIBezierPath()
              path.lineWidth = circleRadius
              path.lineCapStyle = .round

              if drawingAction == .erase {
                  context.cgContext.setBlendMode(.clear)
              } else {
                  context.cgContext.setBlendMode(.normal)
              }

              path.move(to: startPoint)
              path.addLine(to: endPoint)

              UIColor.black.setStroke()
              path.stroke()
          }
      }

      maskImage = image
      maskLayer.contents = maskImage?.cgImage
  }
