Поток 1: сигнал SIGABRT - отлично работает в симуляторе

Question

Я читал об этой ошибке, но я обнаружил, что это касается XIB и коннекторов.

Я посмотрел, но я не могу найти никаких проблем с моими разъемами... Однако я все еще получаю эту ошибку, когда я получаю эту строку кода:

NSMutableString pageData = [pacUtils requestErrorHistory:pac_ipAddr:pacPort];

Это вызывает функцию в классе "pacUtils". Я могу пройти через метод requestErrorHistory, и у него не будет никаких проблем, пока он не вернется к этой строке кода.

Кроме того, он отлично работает в симуляторе...

Это единственная ошибка в моем журнале, но она была там и в последнем выпуске (он работает нормально), потому что я не могу найти ссылку на этот файл png. Даже если я открою XIB в текстовом редакторе.

Я работаю под Xcode 9.1.

Любая помощь будет принята с благодарностью.
