Desc

• No problem with the new install. but, if re-install(build) in xcode after change code then throw NullPointerException.
• I check NSThread.callStackSymbols, it shown 'null' value.

Solution

• Antilog.performTag null-safety
• I don't know why symbol value is null 😢

Thank you! I know it is difficult. But I'd be glad to know how to reproduce it if possible.

@AAkira thks for review 😄

More detail about reproduce step as below

Environment

Apple M1 + xcode with rosetta, Monterey 12.3 Apple intel + xcode, Monterey 12.3 iOS 15.2 iPhone 11 simulator

Reproduce step

1. First run ios-app in xcode is no issue.
2. Re-run app occurs NPE after fixing some code(swift)
   • If delete app and run it, issue does not occur.

Thank you!

I don't have an M1 Mac right now, I will try it when I get it!
