I was able to resolve the crash by disabling AutomaticPushTracking

zihejia commented

hi @grangej , the beta version does not have the automatic push feature, it should also work(pls clear the build cache).

grangej commented

I tried the beta but it was failing on Xcode < 13 , import failed. 😨

I just updated the FBSDK to 9.x (from 8.x) and am encountering this issue for the first time. My project is a React Native app, and we're using Mixpanel through Segment (device mode), so I don't have the option of initializing Mixpanel with automaticPushTracking disabled, nor can I update to using the 4.x beta.

Is this issue caused by the Facebook SDK? Or is there something that can be done in the Mixpanel SDK to prevent this crash?

grangej commented

I really wish apple would block all method swizzling going forward.

zihejia commented

We will provide a fix for this issue. It might due to the conflict between Facebook and Mixpanel for swizzling.

We have released v3.9.0 which we no longer track push by default(automaticPushTracking is NO). We are deprecating Messaging and Mobile A/B testing features(more details), so if you no longer use Mixpanel's messaging feature, another option is to install our 4.0.0.beta version by using SPM(pointing to 4.0.0.beta branch)
