Upload file starting from a specific byte

[tatarinova0903]

Hi! I am using 15.0.0 version of Moya.

I need to upload file to server and listen to uploading progress. I've written this code:

struct StorageUploaderAPI: SignedTargetType {
    let baseURL: URL
    let fileURL: URL
    let blobLength: Int // file length
    let uploadedSize: Int // I should start uploading file from this byte
    let method = Moya.Method.put
    let path = ""

    init(baseURL: URL, fileURL: URL, blobLength: Int, uploadedSize: Int) {
        self.baseURL = baseURL
        self.fileURL = fileURL
        self.blobLength = blobLength
        self.uploadedSize = uploadedSize
    }

    var task: Task {
        .uploadFile(fileURL)
    }

    var apiHeaders: [String: String] {
       ...
    }
}

But it doesn't`t work if I should start uploading file from for example 100th byte.

So I changed creating task to this:

var task: Task {
        var data = try? Data(contentsOf: fileURL)
        if uploadedSize > 0 {
            data = data?.subdata(in: uploadedSize..<blobLength)
        }
        return .requestData(data ?? Data())
 }

But .requestData doesn't`t allow me to listen to progress of the request.

Which case of Task should I use in order to be able to upload file from a specific byte and to listen to uploading progress?
