Module 'Alamofire' has no member named 'upload' - swift

Question

I am trying to upload an image using swift to the server. i tried NSMutableURLRequest with URLSession. i received network connection lost. I thought it will be a better way to simply use Alamofire but got into a problem as xcode doesn't find the function update.
Any idea how to upload image with Alamofire? or find the update func?
the code for alamofire:
func uploadImageWithAlmofire(url: String) {
let params: Parameters = ["name": "abcd", "gender": "Male"]
Alamofire.upload(multipartFormData:
{
(multipartFormData) in
multipartFormData.append(UIImageJPEGRepresentation(self.yourimageView.image!, 0.1)!, withName: "file", fileName: "file.jpeg", mimeType: "image/jpeg")
for (key, value) in params
{
multipartFormData.append((value as AnyObject).data(using: String.Encoding.utf8.rawValue)!, withName: key)
}
}, to:url,headers:nil)
{ (result) in
switch result {
case .success(let upload,_,_ ):
upload.uploadProgress(closure: { (progress) in
//Print progress
})
upload.responseJSON
{ response in
//print response.result
if response.result.value != nil
{
let dict :NSDictionary = response.result.value! as! NSDictionary
let status = dict.value(forKey: "status")as! String
if status=="1"
{
print("DATA UPLOAD SUCCESSFULLY")
}
}
}
case .failure(let encodingError):
break
}
}
}

Answer 1

When you check Uploading Data to a Server example, it uses AF instead of Alamofire:
AF.upload(multipartFormData: { multipartFormData in
multipartFormData.append(Data("one".utf8), withName: "one")
multipartFormData.append(Data("two".utf8), withName: "two")
}, to: "https://httpbin.org/post")
.responseJSON { response in
debugPrint(response)
}

Try with this
AF.upload(multipartFormData: { multipartFormData in
multipartFormData.append(Data(self.businessType.utf8), withName: "business_type")
let theFileName1 = (self.doc1.absoluteString as NSString).lastPathComponent
multipartFormData.append(self.doc1, withName: "key_value", fileName: theFileName1, mimeType: "image/png")
}, to: "https://www.test_document.php") //POST URL
.responseJSON { response in
debugPrint(response)
}
