I do apologize that i have started this tread: refresh SQLITE3 (Core Data) on device and app store and ask again but i am desperate.

问题 I use this statement xcrun simctl list to get device ID list, but it returns different list between Jenkins and terminal, so I can't start simulator via Jenkins.

问题 I'm having an issue with my app that runs fine while running when I run using Xcode or the simulator. Stepping through the debugger isn't any help. I've looked at the crash logs and I can't figure out what the issue is (frankly I don't know how to read them unless one of my objects is explicitly listed).
