    func getWeather() {
        
        AF.request("http://api.openweathermap.org/data/2.5/weather?q="+(vc?.cityTextField.text)!+"&units=metric&appid=88236c7916643a06e2cd64d56f4e5077", method: .get).response{

//            debugPrint(response)
            if let data = response.data
            {
                do{
                    let apiResponse = try JSONDecoder().decode(MyWeatherData.self, from: data)
                    self.modelWeather2.append(apiResponse)

                    debugPrint(apiResponse)
                    DispatchQueue.main.async {
                        
                        self.vc?.tempLabel.text = String(apiResponse.main.temp)
                        self.vc?.titleLabel.text = apiResponse.weather[0].main
                        self.vc?.descriptionLabel.text = apiResponse.weather[0].description
                        let iconUrl = "http://openweathermap.org/img/wn/\(apiResponse.weather[0].icon).png"
                        self.vc?.weatherImage.image = UIImage(named: iconUrl)
                    }
                }catch let error{
                    print(error.localizedDescription)
                }
            }
        }
        
        
    }
}

This is my code

You can use as primitive solution as like the one posted below

extension UIImageView {
    func downloadImage(for url: String) {
        DispatchQueue.global(qos: .default).async {
            if let url = URL(string: url), let data = try? Data(contentsOf: url), let image = UIImage(data: data) {
                self.image = image
            }
        }
    }
}

and finally you can use it as

self.vc?.weatherImage.downloadImage(for: "YOUR_URL_HERE")

Again, solution is highly primitive, doesnt provide caching capability or any other functionalities other than simply downloading the image
