segmentation fault: 11, when using Alamofire.upload

Question

I updated Alamofire to 4.0 for swift 3. (before i was using AFNetworking).

My Code:

func uploadImage(_ image: Data, withURLRequrest urlRequest: URLRequestConvertible, responseCallback: ((NetworkResponse) -> ())? = nil) {


    Alamofire.upload(multipartFormData: { multipartFormData in

        _ = multipartFormData.appendBodyPart(data: image, name: "imagefile", fileName: "image.jpg", mimeType: "image/jpeg")

        }, with: urlRequest) { encodingResult in
            switch encodingResult {
            case .success(let upload, _, _):
                upload.responseJSON { response in
                    switch response.result {
                    case .success(let json):

                        if let responseCallback = responseCallback {
                            responseCallback(.success(Response(response: json)))
                        }

                    case .failure(_): break

                    }

                }
            case .failure(let encodingError): break
            }

    }

}

I get a compile error:

Command failed due to signal: Segmentation fault: 11.

and is the details i get a lot of garbage paths and a stack trace (not from my code)

and in the end:

1. While emitting SIL for 'uploadImage' at */Network/APIManager.swift:64:5

This in pointing to the function above.

Any suggestions? Any other REST request is working (not multipart).

Thanks

The API of multipartFormData has changed.

The append method now look like this (Note that it doesn't return any value):

func append(_ data: Data, withName name: String, fileName: String, mimeType: String)

Here is the example from the Alamofire's README:

Alamofire.upload(
    multipartFormData: { multipartFormData in
        multipartFormData.append(unicornImageURL, withName: "unicorn")
        multipartFormData.append(rainbowImageURL, withName: "rainbow")
    },
    to: "https://httpbin.org/post",
    encodingCompletion: { encodingResult in
        switch encodingResult {
        case .success(let upload, _, _):
            upload.responseJSON { response in
                debugPrint(response)
            }
        case .failure(let encodingError):
            print(encodingError)
        }
    }
)
