Problem getting lat and lon from LocationManager SwiftUI - ios

Question

I'm a beginner, have been working on a weather project, trying to get the lat and long from LocationManager in WeatherViewModel class and pass it the API so i can get the user location based data. but can't get the lattitude and longitude in the WeatherViewModel. the simulator shows a random temperature and city as globe.(SwiftUI and Xcode 11.6)
here's the LocationManager class
import Foundation
import CoreLocation
import Combine
class LocationManager: NSObject, CLLocationManagerDelegate, ObservableObject {
private let manager: CLLocationManager
#Published var lastKnownLocation: CLLocation?
func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
if status == .denied{
print("denied")
}
else{
print("athorized")
manager.requestLocation()
}
}
func start() {
manager.requestWhenInUseAuthorization()
manager.startUpdatingLocation()
}
init(manager: CLLocationManager = CLLocationManager()) {
self.manager = manager
super.init()
}
func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
print(error.localizedDescription)
}
func startUpdating() {
self.manager.delegate = self
self.manager.requestWhenInUseAuthorization()
self.manager.startUpdatingLocation()
}
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
lastKnownLocation = locations.last
print("\((lastKnownLocation?.coordinate.latitude)!)")
print("\((lastKnownLocation?.coordinate.longitude)!)")
}
}
Here's the WeatherViewModel class
import SwiftUI
import Combine
import CoreLocation
class WeatherViewModel: ObservableObject {
#ObservedObject var location = LocationManager()
let client = OpenWeatherAPI()
var stateView: StateView = StateView.loading{
willSet{
objectWillChange.send() }
}
var currentWeather = CurrentWeather.emptyInit(){
willSet{
objectWillChange.send()
}
}
var todayWeather = ForecastWeather.emptyInit(){
willSet{
objectWillChange.send()
}
}
var hourlyWeathers: [ForecastWeather] = [] {
willSet{
objectWillChange.send()
}
}
var dailyWeathers: [ForecastWeather] = [] {
willSet{
objectWillChange.send()
}
}
var currentDescription = ""{
willSet{
objectWillChange.send()
}
}
private var stateCurrentWeather = StateView.loading
private var stateForecastWeather = StateView.loading
var latitude: String{
return "\(location.lastKnownLocation?.coordinate.latitude ?? 0.0)"
}
var longitude: String{
return "\(location.lastKnownLocation?.coordinate.longitude ?? 0.0)"
}
func printLatlon(){
print("WeatherViewModel")
print(latitude )
print(longitude )
}
init (){
getData()
printLatlon()
}
func retry(){
stateView = .loading
stateCurrentWeather = .loading
stateForecastWeather = .loading
}
private func getData() {
client.getCurrentWeather(at: latitude, at: longitude) { [weak self] currentWeather, error in
guard let ws = self else { return }
if let currentWeather = currentWeather {
ws.currentWeather = currentWeather
ws.todayWeather = currentWeather.getForecastWeather()
ws.currentDescription = currentWeather.description()
ws.stateCurrentWeather = .success
} else {
ws.stateCurrentWeather = .failed
}
ws.updateStateView()
}
client.getForecastWeather(at: latitude, at: longitude) { [weak self] forecastWeatherResponse, error in
guard let ws = self else { return }
if let forecastWeatherResponse = forecastWeatherResponse {
ws.hourlyWeathers = forecastWeatherResponse.list
ws.dailyWeathers = forecastWeatherResponse.dailyList
ws.stateForecastWeather = .success
} else {
ws.stateForecastWeather = .failed
}
ws.updateStateView()
}
}
private func updateStateView() {
if stateCurrentWeather == .success, stateForecastWeather == .success {
stateView = .success
}
if stateCurrentWeather == .failed, stateForecastWeather == .failed {
stateView = .failed
}
}
}
I'm passing the data in this
private func getData() {
client.getCurrentWeather(at: latitude, at: longitude) { }
client.getForecastWeather(at: latitude, at: longitude) { }
}
if i use this
var latitude: String{
return "\(location.lastKnownLocation?.coordinate.latitude ?? 0.0)"
}
var longitude: String{
return "\(location.lastKnownLocation?.coordinate.longitude ?? 0.0)"
}
Then i get this output in the simulator
the console shows this
the console shows that it didnt get the lat and lon
but if i give a string of lat and lon like this
var latitude = "36.778259"
var longitude = "-119.417931"
Then i get expected output in the simulator
console output
because I pass the string location and thats why showing my string values
