Problem with MapBox PointAnnotations with data from Alamofire - ios

Question

In my app I need to get annotations coordinates from server, so im getting is with Alamofire request. And when I try to add annotations to map from Alamofire pid im getting unknown error
class MapViewController : UIViewController, MGLMapViewDelegate, FloatingPanelControllerDelegate {
override func viewDidLoad() {
super.viewDidLoad()
....
....
getDataFromServer()
}
func getDataFromServer() {
let coffeeShopsJSON = AF.request("http://194.6*******")
coffeeShopsJSON.responseJSON { response in
switch response.result {
case .success(let value):
let jsonFile = JSON(value)
let arrayCount = jsonFile.array?.count ?? 0
var id = [Int]()
var name = [String]()
var lat = [Double]()
var lon = [Double]()
var img = [UIImage(named : "cofShopIcon"), UIImage(named : "cofShopIcon"), UIImage(named : "cofShopIcon"), UIImage(named : "cofShopIcon"), UIImage(named : "cofShopIcon")] //test images
for i in 0..<arrayCount {
let j_id = jsonFile[i]["id"].string ?? "-1"
id.append(Int(j_id) ?? -1)
let j_name = jsonFile[i]["name"].string ?? "N/A"
name.append(j_name)
let j_lat = jsonFile[i]["coordX"].string ?? "-1.0"
lat.append(Double(j_lat) ?? -1.0)
let j_lon = jsonFile[i]["coordY"].string ?? "-1.0"
lon.append(Double(j_lon) ?? -1.0)
}
for i in 0..<id.count {
mapData.append(coffeeShopsData(shopId : id[i], name : name[i], icon : img[i], latitude : lat[i], longitude : lon[i]))
}
for i in 0..<mapData.count {
let point = MGLPointAnnotation()
point.coordinate = CLLocationCoordinate2D(latitude : mapData[i].latitude ?? 0, longitude : mapData[i].longitude ?? 0)
point.title = mapData[i].name ?? "*Data Error*"
markers.append(point)
}
self.mapView.addAnnotations(markers)
case .failure(let error):
print(error)
}
}
}
}
Error:
libc++abi.dylib: terminating with uncaught exception of type std::domain_error
I'm new in swift, so any advice will be useful
