}
extension ImageService: TargetType {
    public var baseURL: URL { return URL(string: "https://api.shoclef.com/api")! }

    }
    var task: Task {
        switch self {

    case .updateUserAvatar(let user_id, let cover_image):
        let imageData = UIImageJPEGRepresentation(cover_image, 1.0)
        let memberIdData = "\(user_id)".data(using: String.Encoding.utf8) ?? Data()
        var formData: [Moya.MultipartFormData] = [Moya.MultipartFormData(provider: .data(imageData!), name: "cover_image", fileName: "asdas.png", mimeType: "image/jpeg")]
        formData.append(Moya.MultipartFormData(provider: .data(memberIdData), name: "user_id"))
        return .uploadMultipart(formData)
    }
}
public var sampleData: Data {
    return Data()
}
public var headers: [String : String]? {
    switch self {
    case .updateUserAvatar: return ["Content-type" : "application/json"]

    }}}

step 2

@IBOutlet weak var myImage: UIImageView!
    var provider = MoyaProvider()
 @IBAction func uploadImage(_ sender: UIButton) {
        provider.request(ImageService.updateUserAvatar(user_id: 1163, cover_image: myImage.image!)) { result in
            switch result {
            case .success(let response):
                do {

                    let image = try JSONDecoder().decode(Updatecoverimage.self, from: response.data)
                    print(image.data)
                } catch {
                    print(error)  // This code will run because the statusCode is 500
                }

            case .failure(let error):
                print("Failure: \(error)")
            }
        }

    }

}



struct Updatecoverimage: Codable {
    let status, data: String
}
