iOS Swift uploading PDF file with Alamofire (Multipart) : <p>I'm currently developing an application using iOS 10 and Swift 3 and Alamofire 4</p>

<p>The purpose of this application is to upload a PDF file generated previously.</p>

<p>The PDF generation is working perfectly and the file is created.</p>

<p>However the upload doesn’t work… 
I received a success response but the file is not uploaded.</p>

<p><strong>My server response</strong></p>

<pre><code>Multi part Content-Type =&gt; multipart/form-data; boundary=alamofire.boundary.56958be35bdb49cb
Multi part Content-Length =&gt; 293107
Multi part Content-Boundary =&gt; alamofire.boundary.56958be35bdb49cb

    uploadedFiles =     (
                {
            details = " Key=Content-Disposition - values=[form-data; name=\"pdfDocuments\"] length=8";
            storedFileName = "/var/www/pdf/17/009/22/TMP104150531290406.tmp";
            type = PDF;

    );
}

<p>I’m using multi-part to upload my file as Data as you can see <a href="https://github.com/Alamofire/Alamofire#uploading-data-to-a-server" rel="noreferrer">here</a> </p>

<p>File url is fine. </p>

<p>I have searched on SO but didn’t find any solution working… </p>

<p>Here you can see my <strong>Controller</strong></p>

<pre><code>Alamofire.upload(
            multipartFormData: {
                multipartFormData in

                if let urlString = urlBase2 {
                    let pdfData = try! Data(contentsOf: urlString.asURL())
                    var data : Data = pdfData

                    multipartFormData.append(data as Data, withName:"test.pdf", mimeType:"application/pdf")
                    for (key, value) in body {
                        multipartFormData.append(((value as? String)?.data(using: .utf8))!, withName: key)
                    }

                    print("Multi part Content -Type")
                    print(multipartFormData.contentType)
                    print("Multi part FIN ")
                    print("Multi part Content-Length")
                    print(multipartFormData.contentLength)
                    print("Multi part Content-Boundary")
                    print(multipartFormData.boundary)
                }
        },
            to: url,
            method: .post,
            headers: header,
            encodingCompletion: { encodingResult in

                switch encodingResult {

                case .success(let upload, _, _):
                    upload.responseJSON { response in
                        print(" responses ")
                        print(response)
                        print("end responses")

                        onCompletion(true, "Something bad happen...", 200)

                    }
                case .failure(let encodingError):
                    print(encodingError)
                    onCompletion(false, "Something bad happen...", 200)
                }
        })
