UiPickerView не всегда показывает значения в 3g
Привет у меня действительно странная ошибка, приложение в этом приложении использует pattern-view-controller, в представлении я использую UIPickerView отображать имена. Значения должны быть указаны в RisorseUmaneUIPicker! Странно то, что все работает, а когда вы отправляете текстовое сообщение на мобильные устройства в 3g иногда, UIPickerView остается пустым. Как я могу решить это?
Я проверил запрос JSON с почтальоном, и это всегда правильно

Вы можете установить "Network Link Conditioner" из меню XCode: Open Developers Tools > More Developers Tools, Этот инструмент позволяет тестировать в разных условиях сети.
Обработчик передан URLSesssion.dataTask Вероятно, следует передать информацию об успехе или неудаче обратно вызывающей стороне. Теперь он просто возвращает, если произошла ошибка, если данные nil, Попробуйте добавить дополнительное значение помимо данных в обработчик. Например, _ success: Bool может быть передано false в случае ошибки, если данные отсутствуют.
... completion: @escaping (_ success: Bool, _ ret: Codable) -> ()
