Contextual type for closure argument list expects 1 argument, but 4 were specified

Question

I upgraded to Xcode 7 and I am using Alamofire to manage API calls and I am getting this error:

\'Contextual type for closure argument list expects 1 argument, but 4

Answer 1

The closure takes a single parameter of type Response so your code should look more like this.

Alamofire.request(.POST, urlString, parameters: parameters).responseJSON { response in
    let json = JSON(response.data!)
    let token = json["token"].string
    response(token: token)
}
