Getting a crash on release builds in iOS only #565

Closed milesegan closed 5 years ago

milesegan commented 6 years ago

Your Environment

Expected Behavior

The app shouldn't crash.

Actual Behavior

The app crashes on startup.

Steps to Reproduce

Our app crashes right after launch, but only in release builds.

Context

This crash only happens in release builds and only started happening after we upgraded to the most recent version of react native. We've been using it with older versions of RN without issues. The stack trace isn't very useful here unfortunately. It looks to me like it might be some kind of memory corruption issue.

@Peeeep Try installing the plugin from git using the following url:

npm install https://github.com/transistorsoft/react-native-background-geolocation.git#ios-sync-bug

I've only played around with the Simulator, but unfortunately, I can get it to crash quite easily now... (I believe I wasn't able to crash it in the Simulator before, but hadn't tried very hard tbh).

I've pushed some try/catch blocks to the repo, maybe this can help a bit... Will get back to you with some real device data plus a stacktrace by tomorrow (I'm UTC+2), please let me know if there is anything else I can help with!

Your installed version is 2.14.2?

Peeeep commented 5 years ago

Yes, the ios-sync-bug branch.

Peeeep commented 5 years ago

Sorry for the late reply, but this now works perfectly for us! You got yourself a fully satisfied paying customer, thank you!

@christocracy, I have the same crashlog, but my project is different. I'll very much appreciate if you provide a hint of what did you fix in iOS code to get rid of this crash?
