ResponseDetective is a non-intrusive framework for intercepting any outgoing requests and incoming responses between your app and your server for debugging purposes.

Requirements

ResponseDetective is written in Swift 3 and supports iOS 8.0+, macOS 10.10+ and tvOS 9.0+.

Usage

Incorporating ResponseDetective in your project is very simple – it all comes down to just two steps:

Step 1: Enable interception

For ResponseDetective to work, it needs to be added as a middleman between your (NS)URLSession and the Internet. You can do this by registering the provided URLProtocol class in your session's (NS)URLSessionConfiguration.protocolClasses, or use a shortcut method:

// Objective-C

NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
[RDTResponseDetective enableInConfiguration:configuration];

// Swift

let configuration = URLSessionConfiguration.default
ResponseDetective.enable(inConfiguration: configuration)

Then, you should use that configuration with your (NS)URLSession:

// Objective-C

NSURLSession *session = [[NSURLSession alloc] initWithConfiguration:configuration];

// Swift

let session = URLSession(configuration: configuration)

Or, if you're using AFNetworking/Alamofire as your networking framework, integrating ResponseDetective comes down to just initializing your AFURLSessionManager/Manager with the above (NS)URLSessionConfiguration:

// Objective-C (AFNetworking)

AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];

// Swift (Alamofire)

let manager = Alamofire.Manager(configuration: configuration)

And that's all!

Step 2: Profit

Now it's time to perform the actual request:

// Objective-C

NSURLRequest *request = [[NSURLRequest alloc] initWithURL:[NSURL URLWithString:@"http://httpbin.org/get"]];
[[session dataTaskWithRequest:request] resume];

// Swift

let request = URLRequest(URL: URL(string: "http://httpbin.org/get")!)
session.dataTask(with: request).resume()

Voilà! 🎉 Check out your console output:

<0x000000000badf00d> [REQUEST] GET https://httpbin.org/get
 ├─ Headers
 ├─ Body
