Hey swift forums, I’m having trouble launching a completed Rock Paper Scissors game. This is lesson 20 from the introduction to app development with swift iBook. I receive a SIGABRT ERROR, building the app succeeds but then I receive a white screen. Any help at all would be greatly appreciated. Thank you.
DEBUG AREA:
2019-06-23 20:11:20.811780-0400 Rock Paper Scissors[5220:106660] [general] CFLocaleCopyCurrent() failed to look up current locale via 'AppleLocale' and 'AppleLanguages' in user preferences; falling back to locale identifier 'en_US' as the default. Consider checking Console for sandbox violations from this process for reading from preferences, or enabling CoreFoundation debug logging for more information. This will only be logged once.
