It looks like AGSIdentifyLayerResult is passively generated from AGSGeoViewTouchDelegate functions rather than 'on the fly'.   ... View more

I got persistence! I was able to serialize and de-serialize an AGSPolyLine (free sketch): let lineSymbol = AGSSimpleLineSymbol(style: .solid, color: UIColor.red, width: 3)  let myPolyLine = UserDefaults.standard.value(forKey: SketchItem.Doodle.desc())  let polyline2 = (try? AGSPolygon.fromJSON(myPolyLine!)) as! AGSPolyline  graphicsOverlay.graphics.add(AGSGraphic(geometry: polyline2, symbol: lineSymbol, attributes: nil))  mapView.graphicsOverlays.add(graphicsOverlay) I'll cleanup the code.... but it works. Again, Thanks for your speedy answer! ... View more

Thanks for the speedy reply! I was thinking... Perhaps converting the AGSPolyLine to a Swift Array:  doodle.parts.array() as? Array ...where 'doodle' is a free-form sketch of type AGSPolyLine. Then I could transform the Array into a NSData item for serialization. Of course I would have to reverse all this back to AGSPolyLine. ... is this possible? In the meantime, I'll go the JSON route per your example. ... View more

Reference: ESRI's Sketch Example: Environment: iOS/Swift 3.0+ I notice that no overlays are used in the sketch, which uses the AGSSketchEditor. However I believe I need the use of a graphics overlay object to display historical sketches. Hence I've added the following:  private var myPolyLine:AGSPolyline?  private var graphicsOverlay = AGSGraphicsOverlay() 1) Making a copy of the sketch as a 'geometry':  @IBAction func clear() {         self.myPolyLine = self.sketchEditor.geometry!.copy() as? AGSPolyline         self.sketchEditor.clearGeometry()     } 2) Restoring the sketch after 'deleting' it: case 3: // ...redraw             let lineSymbol = AGSSimpleLineSymbol(style: .solid, color: UIColor.red, width: 3)             self.graphicsOverlay.graphics.add(AGSGraphic(geometry: self.myPolyLine, symbol: lineSymbol, attributes: nil))             self.mapView.graphicsOverlays.add(self.graphicsOverlay) I needed to create a graphics overlay to display the copy. I can see the buildup of graphicOverlays. So once I don't need this copy, I should REMOVE this particular overlay.  That is, each overlay would contain a previously-copied sketch and hence, I should discard these overlays once not needed.   Correct? As for persistent storage: a AGSPolyline is an NSObject so I could serialize it for storage accordingly. Is this the correct way for creating a persistent store of a sketch and handling old sketches via removing the overlays? ... View more

Thanks for the quick response! I'm going to play with this per your directive. Ric. ... View more
