        print("Invalid URL")
        completion(nil)

    URLSession.shared.dataTask(with: url) { data, response, error in
        guard let data = data, error == nil else {

        // Print the raw JSON data for inspection
        if let jsonString = String(data: data, encoding: .utf8) {

// Usage
fetchCountryData { countries in

            print("------")
        }
    } else {
        print("Failed to fetch country data.")
