无法将类型'（_，_，_）->（）'的值转换为预期的参数类型'Int64'

Question

upload(urlRequest.1, with: urlRequest.0)
        Progress {(bytesWritten, totalBytesWritten, totalBytesExpectedToWrite) in // Error Comes Here
                print("\(Int64(totalBytesWritten)) / \(Int64(totalBytesExpectedToWrite))")
            }
            .responseJSON
            {
                response in

                hideLoading()

                showToast("Profile Updated Successfully!!")
            }

Answer 1

The problem is that you've replaced .uploadProgress with Progress , but have not changed the three parameters to the closure to be the single Progress parameter.

When you call .uploadProgress , the first parameter to that closure is a Progress (formerly known as NSProgress ). But the Alamofire method name, uploadProgress , is unchanged. Only the parameters to the closure have changed.

Thus you want something like:

Alamofire.upload(data, with: request)
    .uploadProgress { progress in
        print(progress.fractionCompleted)
    }
    .responseJSON { response in
        self.hideLoading()

        switch response.result {
        case .failure(let error):
            self.showToast("Problem uploading: \(error.localizedDescription)")
        case .success:
            self.showToast("Profile Updated Successfully!!")
        }
}

Bottom line, the upload progress method is called uploadProgress , and it takes one parameter, a NSProgress / Progress object.
