@kafejo is this crashing on all iOS 10 devices and lower (including non-jailbroken ones)? If so, is the stack trace identical?

[kafejo]

@morganchen12 no, only on jailbroken.

[morganchen12]

It looks like your code is crashing deep in the Security framework. It's unlikely that Firebase is the root cause of this, and it will likely not be a priority for us to debug.

@salqadri can probably speak more to our support on jailbroken devices.
