Я изучал Xamarin и теперь начинаю с Xamarin Classi c. Я использую в конце 2014 года Ma c mini, который довольно медленный. Я установил Xcode и Visual Studio, но когда я пытаюсь открыть любой файл .storyboard, колесо некоторое время вращается, а затем выдается исключение MonoTouch.Design.Client.InvalidSessionException. Он отвечает на код 165 CoreSimulator.SimError: Невозможно стереть содержимое и настройки в текущем состоянии: Booted
У меня установлена самая последняя версия Visual Studio и Xcode 11.4. Я попытался запустить sudo xcrun simctl shutdown all как перед загрузкой файла Main.storyboard, так и во время загрузки файла (что было рекомендовано в StackOverflow), но ни один из них не сработал.
Я сбит с толку как к чему приводит эта ошибка. Хотя мне удалось найти информацию об ошибке MonoTouch.Design.Client.InvalidSessionException и CoreSimulator.SimError, я не смог найти их обоих вместе.
Я абсолютно не знаю, что вызывает это произойдет. Я попытался перейти на Mojave, но это не сработало, поскольку Xcode 11.4 был необходим для VS, и для этого требуется Catalina.
Вот (обрезанное) сообщение об ошибке из Visual Studio.
System.AggregateException: One or more errors occurred. (One or more errors occurred. (Exception of type 'MonoTouch.Design.Client.InvalidSessionException' was thrown.)) ---> System.AggregateException: One or more errors occurred.
