Alamofire Response Property List

Question

I'm going through a tutorial and am attempting to make an alamofire request to a property list. In the closure for the response property list, I use the arguments (_, _, result). However, XCode gives me the error:

Cannot convert value of type '(_, _, _) -> Void' to expected argument type 'Response -> Void'

I am using alamofire 3.0 beta.

Alamofire right now is in version 3.3 according to the releases in the repository, since the version 3.0 it has change a little.

In you use the Response Handler your closure need to look like this:

Alamofire.request(.GET, "https://httpbin.org/get", parameters: ["foo": "bar"])
     .response { request, response, data, error in
         print(request)
         print(response)
         print(data)
         print(error)
      }

And if you use for example the Response JSON Handler everything is encapsulated now in the response like in this code:

Alamofire.request(.GET, "https://httpbin.org/get", parameters: ["foo": "bar"])
     .responseJSON { response in
         print(response.request)  // original URL request
         print(response.response) // URL response
         print(response.data)     // server data
         print(response.result)   // result of response serialization

         if let JSON = response.result.value {
             print("JSON: \(JSON)")
         }
     }

Or you can use this code for more easily handling:

Alamofire.request(.GET, "https://httpbin.org/get", parameters: ["foo": "bar"])
     .responseJSON { response in
         switch(response.result) {
         case .Success(let value):
            if let JSON = value {
              print("JSON: \(JSON)")
            }
         case .Failure(let error):
            print(error.description)    
         }
     } 

I hope this help you.
