OUTDATED: Updating a UILabel to display current location

Question

TLDR;

I want to get locations outside the main thread using a different function but I am receiving delays.

In details:

I'm performing a GET request. later on I parse the JSON to get the current locaction in a method called 'locationManager' now I have a UILabel outlet that I want to update all the time to the current location displayed on the map according to the result of the JSON (does reverse geocode) but if I access the label.text through the locationManager I have a delay + Xcode tells me that it should only be done through the main thread.

so I've tried making a global variable and updating it in the locationManager but then when I access the label.text in viewDidLoad() and feed it the global variable it stays empty (initial value)

what could be a possible fix to this?

var addrs = "" // the global variable 

...

  func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    //Code
     addrs = result.response.view[0].result[0].location.address.label
    } .resume()
    

override func viewDidLoad() {
  super.viewDidLoad()
  locationLabel.text = ("Your Current Location Is :" + addrs)
}

Note: Always update your UI's only on the main thread. Use below code to resolve your issue.

DispatchQueue.main.async { [weak self] in
    addrs = result.response.view[0].result[0].location.address.label
    self?.locationLabel.text = ("Your Current Location Is :" + addrs)
}
