Save and retrieve the CGPath in CoreData iOS swift

Problem:

I want to save the CGpath to the Coredata and retrieve the path and redraw it.


Solution:

Save to coredata:

let objDict = NSMutableDictionary()

              objDict.setValue(NSKeyedArchiver.archivedData(withRootObject: Color), forKey: "color")

  let bezierPath = UIBezierPath(cgPath: tool.penPath)

objDict.setValue(bezierPath, forKey: "Path")

  objDict.setValue(NSNumber(value: Double(tool.lineWidth)), forKey: "width")

            

From coredata and redraw:

let path = k.value(forKey: "Path")

let shapeView: CAShapeLayer = CAShapeLayer.init()

 shapeView.path = (path as! UIBezierPath).cgPath

  shapeView.strokeColor = UIColor.white.cgColor

 shapeView.lineWidth = CGFloat(k.value(forKey: "width") as! Double)                    self.ciew.layer.addSublayer(shapeView)
