Crash on launch #2

Closed joshkopecek closed 4 years ago

joshkopecek commented 4 years ago

I am getting an Exception when loading the lib. It's caused when invoking PHGPostHog.setup(with: configuration).

This happens no matter whether I enable captureApplicationLifecycleEvents or not (since it's related to applicationDidFinishLaunching.

I can confirm disabling line 95 in PHGPayloadManager.m temporarily fixes the crash. This is only a workaround though, as it disables the lifecycle analytics.

Hi @joshkopecek , thanks for raising this! I have managed to replicate the problem and I'm working on finding a fix. I'll keep you posted, although it might take until Monday.

joshkopecek commented 4 years ago

Thank you @mariusandra ! I'll keep an eye on this thread.

mariusandra commented 4 years ago

Hi again @joshkopecek , all these issues should be fixed with version 1.0.2 of the library. Please try it out and let me know if it works!

joshkopecek commented 4 years ago

@mariusandra just checked and that fixed it. Thanks for the prompt response!

mariusandra commented 4 years ago

Awesome! Please let me know if there's anything else I can help with :)
