How to parse JSON response from Alamofire API in Swift?

The answer for Swift 2.0 Alamofire 3.0 should actually look more like this:

Alamofire.request(.POST, url, parameters: parameters, encoding:.JSON).responseJSON{ response in switch response.result {                case .Success(let JSON):                    print("Success with JSON: \(JSON)")                    let response = JSON as! NSDictionary                    //example if there is an id                    let userId = response.objectForKey("id")!                case .Failure(let error):                    print("Request failed with error: \(error)")                }    }

UPDATE for Alamofire 4.0 and Swift 3.0 :

Alamofire.request(url, method: .post, parameters: parameters, encoding: JSONEncoding.default)            .responseJSON { response in                print(response)//to get status code                if let status = response.response?.statusCode {                    switch(status){                    case 201:                        print("example success")                    default:                        print("error with response status: \(status)")                    }                }//to get JSON return value            if let result = response.result.value {                let JSON = result as! NSDictionary                print(JSON)            }        }

like above mention you can use SwiftyJSON library and get your values like i have done below

Alamofire.request(.POST, "MY URL", parameters:parameters, encoding: .JSON) .responseJSON{    (request, response, data, error) invar json = JSON(data: data!)       println(json)          println(json["productList"][1])                 }

my json product list return from script

{ "productList" :[{"productName" : "PIZZA","id" : "1","productRate" : "120.00","productDescription" : "PIZZA AT 120Rs","productImage" : "uploads\/pizza.jpeg"},{"productName" : "BURGER","id" : "2","productRate" : "100.00","productDescription" : "BURGER AT Rs 100","productImage" : "uploads/Burgers.jpg"}      ]}

output :

{  "productName" : "BURGER",  "id" : "2",  "productRate" : "100.00",  "productDescription" : "BURGER AT Rs 100",  "productImage" : "uploads/Burgers.jpg"}

Swift 3, Alamofire 4.4, and SwiftyJSON:

Alamofire.request(url, method: .get)  .responseJSON { response in      if response.data != nil {        let json = JSON(data: response.data!)        let name = json["people"][0]["name"].string        if name != nil {          print(name!)        }      }  }

That will parse this JSON input:

{  people: [    { name: 'John' },    { name: 'Dave' }  ]}
