Answer 1

Try this.

Initiate your session using custom session config as shown below:

let session = URLSession(configuration: URLSessionConfiguration.ephemeral,
                                 delegate: self,
                                 delegateQueue: nil)

Implement the following delegate callback method:

public func urlSession(_: URLSession, task _: URLSessionTask, didReceive challenge: URLAuthenticationChallenge, completionHandler: @escaping (URLSession.AuthChallengeDisposition, URLCredential?) -> Void) {
    guard let serverTrust = challenge.protectionSpace.serverTrust else {
        return completionHandler(URLSession.AuthChallengeDisposition.useCredential, nil)
    }
    return completionHandler(URLSession.AuthChallengeDisposition.useCredential, URLCredential(trust: serverTrust))
}

If you are using AFNetworking, you can use this code:

(Just as a temp client-side solution!)

AFHTTPSessionManager * apiManager = [AFHTTPSessionManager initWithBaseURL:[NSURL URLWithString:baseURL];
AFSecurityPolicy *policy = [AFSecurityPolicy policyWithPinningMode:AFSSLPinningModeNone];
policy.allowInvalidCertificates = YES;
apiManager.securityPolicy = policy;
