Alamofire Contextual type for closure Error

Question

I have the following error after upgrading Alamofire to version 2.0.0.0 using Swift 2

Anyone know a fix for this?

Answer 1

The Request Serialisation, ie responseJson changed signatures in AlamoFire 2.0. The Migration Guide explains in full, but the abbreviated version is as follows.

You now need to supply a closure which takes a request , a response , and a result . The result is an enum , which can either be .Success(Value) or .Failure(NSData?, ErrorType) .

So your code should look something like this:

Alamofire.request(.GET, urlString, parameters: params, encoding: .URL)
    .responseJson(options: .MutableContainers) { (request, response, result) -> Void in
        print(result)
    }
