Uruchomiłem Xcode, aby nauczyć się tworzyć aplikacje na iOS. Wszystko działało dobrze, ale Xcode wciąż zamarzał, a ja na wpół zmuszałem się do rezygnacji. Sugerowano ponowne zainstalowanie Xcode. Zrobiłem to i wyglądało na to, że ponownie się instaluje.
Teraz jednak uruchamia się Xcode, ale nie otworzy pliku Main.storyboard. Otwiera się i możesz edytować pliki tekstowe, ale kiedy próbuję otworzyć Main.storyboard lub LaunchScreen.storyboard, ikona przypominająca koło zębate zaczyna się obracać, ale nigdy nie ładuje pliku.
Czy ktoś może mi pomóc w uruchomieniu Xcode.
Używam High Sierra 10.13.6 i Xcode 10.1.
Oto kod źródłowy Main.storyboard
