Calling locationManager within a IBAction function - swift

Question

I'm working on a weather application and I want the user to get data about the weather either by inserting a location or by the current GPS location.
For the GPS location, there is a push button in the interface that can be pressed. At the click of the button, I want to call the locationManager function, but it does not work. Do you think it's something linked with the scope?
I simply put the locationManager function into the IBAction function of the button. That's because I do not know how to call locationManager within IBAction.
class ViewController: UIViewController, CLLocationManagerDelegate {
let key = "d79ac3fea08fac5d21deeabef00*****"
var lat = 11.344533
var lon = 104.33322
let managLoc = CLLocationManager()
#IBAction func locationOption(_ sender: Any, forEvent event: UIEvent) {
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
let location = locations[0]
lat = location.coordinate.latitude
lon = location.coordinate.longitude
Alamofire.request("https://api.openweathermap.org/data/2.5/weather?lat=\(lat)&lon=\(lon)&appid=\(key)").responseJSON {
response in
if let responseStr = response.result.value {
let jsonResponse = JSON(responseStr)
let jsonWeather = jsonResponse["weather"].array![0]
let jsonTemp = jsonResponse["main"]
let iconName = jsonWeather["icon"].stringValue
self.locationLabel.text = jsonResponse["name"].stringValue
self.typeView.image = UIImage(named: iconName)
self.typeLabel.text = jsonWeather["main"].stringValue
self.tempLabel.text = "\(Int(round(jsonTemp["temp"].doubleValue-273.15)))"
let date = Date()
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "EEEE"
self.dayLabel.text = dateFormatter.string(from: date)
}
}
self.managLoc.stopUpdatingLocation()
}
func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
print(error.localizedDescription)
}
}

Get the locationManager functions out of the action
class ViewController: UIViewController, CLLocationManagerDelegate {
let key = "d79ac3fea08fac5d21deeabef00*****"
var lat = 11.344533
var lon = 104.33322
let managLoc = CLLocationManager()
override func viewDidLoad() {
super.viewDidLoad()
managLoc.delegate = self
}
#IBAction func locationOption(_ sender: Any, forEvent event: UIEvent) {
self.managLoc.startUpdatingLocation()
}
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
let location = locations[0]
lat = location.coordinate.latitude
lon = location.coordinate.longitude
Alamofire.request("https://api.openweathermap.org/data/2.5/weather?lat=\(lat)&lon=\(lon)&appid=\(key)").responseJSON {
response in
if let responseStr = response.result.value {
let jsonResponse = JSON(responseStr)
let jsonWeather = jsonResponse["weather"].array![0]
let jsonTemp = jsonResponse["main"]
let iconName = jsonWeather["icon"].stringValue
self.locationLabel.text = jsonResponse["name"].stringValue
self.typeView.image = UIImage(named: iconName)
self.typeLabel.text = jsonWeather["main"].stringValue
self.tempLabel.text = "\(Int(round(jsonTemp["temp"].doubleValue-273.15)))"
let date = Date()
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "EEEE"
self.dayLabel.text = dateFormatter.string(from: date)
}
}
self.managLoc.stopUpdatingLocation()
}
func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
print(error.localizedDescription)
}
}
