Swift 5.1

Your class has to comply with URLSessionDelegate and implement the "didReceive Challenge" function.

These Apple Developer pages illustrates the issue and provides a lot of insight on how to securely fix this issue:

Handling an Authentication Challenge

Performing Manual Server Trust Authentication

Here is an example of how to fix this issue for Dev or QA environments:

func urlSession(_ session: URLSession, didReceive challenge: URLAuthenticationChallenge, completionHandler: @escaping (URLSession.AuthChallengeDisposition, URLCredential?) -> Void) {
    #if DEBUG
    if challenge.protectionSpace.authenticationMethod == NSURLAuthenticationMethodServerTrust {
        if challenge.protectionSpace.host == "YourTrustedDevOrQaDomain" {
            // At this point you can prevent a domain that is pretending to be a trusted domain by challenging the user to present some credentials or a security mechanism for authentication. 
            if let serverTrust = challenge.protectionSpace.serverTrust {
                let credential = URLCredential(trust: serverTrust)
                completionHandler(URLSession.AuthChallengeDisposition.useCredential, credential)
            }
        }
    }
    #endif
