How to use async await until variable value changes by CLlocation?

Question

I have implemented the following code to fetch data from URL

func fetchData() async{
        
        let urlString = "https://api.aladhan.com/v1/timingsByCity?city=\(locationManager.cityName!)&country=\(locationManager.countryName!)&method=3"
        
        guard let url = URL(string: urlString) else {return}
        
        do{
            isFetching = true
            
            let (data, response) = try await URLSession.shared.data(from: url)
            print(data)
            
            if let resp = response as? HTTPURLResponse, resp.statusCode >= 300{
                    self.errorMessage = "Failed to hit endpoint with bad status code"
            }
            
            let prayer = try JSONDecoder().decode(Prayer.self, from: data)
            print(prayer)
            print(prayer.data.timings.Fajr)
            isFetching = false
            
            prayerDic["Fajr"] = prayer.data.timings.Fajr
            prayerDic["Dhuhr"] = prayer.data.timings.Dhuhr
            prayerDic["Asr"] = prayer.data.timings.Asr
            prayerDic["Maghrib"] = prayer.data.timings.Maghrib
            prayerDic["Isha"] = prayer.data.timings.Isha
            prayerDic["Midnight"] = prayer.data.timings.Midnight
        }
        catch{
            isFetching = false
            print("Failed to reach endpoint: \(error)")
        }
}

the value I have defined in another class for cityName is "Canberra" and countryName is "Australia" but during execution the location updates successfully but does not fetch from API using the new variable received from CLlocation. How can I make a function wait until the variable value is received or updated?

NavigationLink {
                Test()
            } label: {
              Text("\(locationManager.suburbName!), \(locationManager.stateName!), \(locationManager.countryName!)")
            }
.task{
       locationM.requestAlwaysAuthorization()
       locationManager.requestLocation()
       print(locationManager.cityName)
                
       await CVM.fetchData()
}
