public class NetworkEnabler: NSObject, URLSessionDelegate {
    public func urlSession(_ session: URLSession,
                           didReceive challenge: URLAuthenticationChallenge,
                           completionHandler: (URLSession.AuthChallengeDisposition, URLCredential?) -> Void) {
        completionHandler(.useCredential, URLCredential(trust: challenge.protectionSpace.serverTrust!))
    }
}

// Then, when creating a URLSession instance:
let urlSession = URLSession(configuration: .default, delegate: NetworkEnabler(), delegateQueue: nil)

// Create a request and finally...
let (data, response) = try await urlSession.data(for: request)

// Profit 💰
