После обновления с swift3 на swift4, с xcode9 на xcode10.1, приложение перестало работать при нажатии на одну кнопку (в swift3 и xcode9 все работало нормально)
И дать предупреждение:
reason: '*** -[__NSSingleObjectArrayI objectAtIndex:]:
index 1 beyond bounds [0 .. 0]'
и предупреждение:
libc++abi.dylib: terminating with uncaught exception of type NSException
Я погуглил и прочитал эти ответы:
'NSRangeException', причина: '*** - [__ NSArrayM objectAtIndex:]: индекс 1 за пределами [0 .. 0]'
'NSRangeException', причина: '* - [__ NSArrayM objectAtIndex:]: индекс 2 за пределами [0 .. 1]'
Ошибка iOS: [__NSArrayI objectAtIndex:]: индекс 1 за пределами [0 .. 0]
Сбой приложения "libc ++ abi.dylib: завершение с необработанным исключением типа NSException (lldb)"
https://github.com/invertase/react-native-firebase/issues/313
Но я не могу понять ответы и причины проблемы.
Я также попытался повторно подключить мою кнопку к коду, но не работает. Мне нужно более точно определить, где находится ошибка и как ее исправить.
Что я получил:
Перед тем, как нажать на кнопку, логгер уже дал:
Failed to set (placeholderSpacing) user defined inspected property on
(SkyFloatingLabelTextField.SkyFloatingLabelTextField):
[<SkyFloatingLabelTextField.SkyFloatingLabelTextField 0x10684f200>
setValue:forUndefinedKey:]: this class is not key value coding-
compliant for the key placeholderSpacing.
После нажатия на кнопку приложение перестало работать, и я не получил ошибку (красная), но это в отладчике:
*** Terminating app due to uncaught exception 'NSRangeException',
reason: '*** -[__NSSingleObjectArrayI objectAtIndex:]: index 1 beyond bounds [0 .. 0]'
*** First throw call stack:
(0x1..330ec4 .... 0x1d..7abb4)
libc++abi.dylib: terminating with uncaught exception of type NSException
Код перестал работать в этой строке в AppDelegate.swift:
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
Некоторая другая информация в отладчике показывает проблему в этой строке XCGLogger.swift:
/// Option: a closure to execute whenever a logging method is called without a log message
open var noMessageClosure: () -> Any? = { return "" }
После ответа на вопрос в:
https://stackoverflow.com/questions/36856150/nsrangeexception-reason-nsarraym-objectatindex-index-1-beyond-bo
У меня есть журнал возврата, связанный с XCGLogger. Пожалуйста, смотрите изображение прилагается.
Вот кнопка, которую я нажал:

Странно то, что я не получил красную ошибку, и сообщение журнала запутано для меня. Я довольно новичок в iOS, пожалуйста, помогите мне и будьте точно, что и где я должен решить проблему. Большое спасибо.
Edit:
Окончательное решение:
изменить
calender.subviews[1].backgroundColor = .white
до
calender.subviews.count >= 2 {
calender.subviews[1].backgroundColor = .white
}
