How to add flag image from an API?

Question

import UIKit

class DetailsViewController: UIViewController {
   @IBOutlet weak var alpha3CodeLbl: UILabel!
   @IBOutlet weak var regionLbl: UILabel!
   @IBOutlet weak var flagImage: UIImageView!

    var countrie:jsonStruct?


    override func viewDidLoad() {
        super.viewDidLoad()
        alpha3CodeLbl.text = countrie?.alpha3Code
        regionLbl.text = countrie?.region
        let urlString = "http://restcountries.eu/rest/v2/all" + (countrie?.flag)!

        flagImage.downloadedFrom(url: url!)


    }
}

extension UIImageView {
    func downloadedFrom(url: URL, contentMode mode: UIViewContentMode = .scaleAspectFit) {
        contentMode = mode
        URLSession.shared.dataTask(with: url) { data, response, error in
            guard
                let httpURLResponse = response as? HTTPURLResponse, httpURLResponse.statusCode == 200,
                let mimeType = response?.mimeType, mimeType.hasPrefix("image"),
                let data = data, error == nil,
                let image = UIImage(data: data)
                else { return }
            DispatchQueue.main.async() {
                self.image = image
            }
            }.resume()
    }
    func downloadedFrom(link: String, contentMode mode: UIViewContentMode = .scaleAspectFit) {
        guard let url = URL(string: link) else { return }
        downloadedFrom(url: url, contentMode: mode)
    }
}

I'm trying to get the flag image form this API http://restcountries.eu/rest/v2/all

There is no error but the image does not appear. But there is no result if there anyone here can fix this issue. Please, not that everything is okay and try to get the image in too many ways but still no result.

Also, I try this

    let urlString = "http[enter image description
 here][1]://restcountries.eu" + (countrie?.flag)!

A few things to fix. You should test the url before using it.

let str = "yourURL"
guard let theUrl = URL(string: str) else { return }

As mentioned by @rmaddy in a comment above, UIImage isn't going to work with SVG files. Use a UIWebView instead

var request = URLRequest(url:theUrl)
webView.loadRequest(request)

Or try SVGKit to convert SVG as described here
