I was trying to figure out how to get rid of a lot of warning on my council and I came to the conclusion that these warnings happens just after I add overlays to my mapKit
here's the part where I add the overlays..
let FireLocation = CLLocationCoordinate2D(latitude: 40.836352, longitude: 14.306019)
let CircularRegion = CLCircularRegion(center: FireLocation, radius: 500, identifier: "fire")
CircularRegion.notifyOnEntry = true
CircularRegion.notifyOnExit = true
self.locatManager.startMonitoring(for: CircularRegion)
let geo = MKCircle(center: FireLocation, radius: CircularRegion.radius)
mapkitView.addOverlay(geo)
after that I customize these overlays on the delegate method...
func mapView(_ mapView: MKMapView, rendererFor overlay: MKOverlay) -> MKOverlayRenderer {
guard let circularOverlay = overlay as? MKCircle else {return MKOverlayRenderer()}
let renderer = MKCircleRenderer(overlay: circularOverlay)
renderer.strokeColor = .red
renderer.fillColor = .yellow
renderer.alpha = 0.3
renderer.lineWidth = 2
return renderer
}
the warnings I got on the console...
2018-10-25 15:09:04.919237+0200 SeeFire[37911:13344200] This application is modifying the autolayout engine from a background thread after the engine was accessed from the main thread. This can lead to engine corruption and weird crashes. 2018-10-25 15:09:04.921562+0200 SeeFire[37911:13344200] This application is modifying the autolayout engine from a background thread after the engine was accessed from the main thread. This can lead to engine corruption and weird crashes.
if I comment the lines where I add the overlay no warnings appear and everything goes just fine, what am I doing wrong?
what's the difference between MKCircleRenderer and MKCircleView how do I know which one should I use?
thank you in advance for the answers.
