Редактировать: Я добавил код нижеНе удалось загрузить модель под названием «Название проекта»
Я столкнулся с этой ошибкой, которая сводит меня с ума. Раньше у меня было сообщение об ошибке, что сказал:
libc++abi.dylib terminating with uncaught exception of type NSException (lldb)
и нашел решение здесь: https://www.youtube.com/watch?v=YMi5lPetGy4&t=220s
Однако, теперь у меня есть сообщение об ошибке:
2017-01-15 21:44:39.059880 بزنسي[27654:918259] [error] error: Failed to load model named DreamLister CoreData: error: Failed to load model named DreamLister 2017-01-15 21:44:39.191 بزنسي[27654:918259] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'An instance of NSFetchedResultsController requires a non-nil fetchRequest and
DreamLister не приложение Я пытаюсь запустить. Итак, я не знаю, почему это показано, когда я пытаюсь запустить другое приложение!
بزنسي - это имя приложения, с которым у меня проблема.

Исключено, что ваше приложение ищет модель CoreData 'DreamLister', которая, кажется, отсутствует в приложении, добавьте ее, она должна работать. – iphonic
Я ценю ваш комментарий, но вещь DreamLister - совсем другое приложение. Я не помню, чтобы добавить что-нибудь с именем «DreamLister». Для меня это не имеет никакого смысла. – user2066392
Откройте свою Coredata, должно быть что-то связано с DreamLister. – iphonic
