TwilioChatClient crash in CFNetwork/web socket, EXC_BAD_ACCESS


I am using the latest TwilioChatClient version 5.0.0

I got a crash in login function each time I try to login with access token, however this crash doesn't happen in quick start project provided by Twilio.

Here's what I got from symbolicated crash log.

I have contacted the support but we couldn't find the real reason behind the crash. Unfortunately, it's not open source, so I couldn't debug the crash inside the framework.


Solution

  • After some debugging, I found that there is another pod conflicting with this one called Netfox

    I believe that both are using web sockets and somehow they were conflicted with each other.
