ПРИМЕЧАНИЕ: Я сам участвую в себе. Я работаю с Swift в течение последних нескольких дней. У меня есть приложение, которое учит меня основам.Swift - Ожидаемая декларация В декларации 'View Controller'
Итак, я прочитал, и я нашел две возможные причины для этой ошибки. 1. Это у меня нет кода в методе/функции 2. Является ли я отсутствует}
Так это только подчеркивает:
class ViewController: UIViewController, UIPickerViewDelegate
Он также ставит маленькую красную стрелку под V в ViewController. Тогда ошибка гласит:
- В декларации «View Controller»
Я не уверен, что еще может быть возможность. Единственным кодом, который не является частью функции, являются объявления массива. Я поместил их сразу после @IBOutlets и сразу же после переопределения func. Все остальное находится в функции override или func.
