We updated from 2.0.1 to 3.0.2 and I can now see some crashes coming from Trustkit. We only have call stack as this happens with our production app.

Hi, I am facing the same issue with my application only in production, If you find any solution for this then please share, It will be helpful to us. Thanks

This is now worst crash and would be nice to get this fixed.

Hello, is this crash still happening on v3.0.3?

[wmfeuvrel]

With 3.0.2 I was getting this crash at app launch.
The IOS crash report from TestFlight stated the crash reason as CODESIGNING 2 Invalid Page in thread calling CFNetwork __NSCFURLSessionDelegateWrapper didReceiveChallenge:completionHandler.

A separate symbolicated crash report further identified the issue as ssl_pin_verifier.m - Line 43. It only occurred in release builds, and only on device.

Upgraded to trustkit 3.0.4 and the issue resolved.
