iOS Crash on NSMapTable { } count underflow

Question

Hi,

Do you have any suggestions on where to start to look for the following crash:

-[AGSNSURLSessionDemultiplexer URLSession:task:didCompleteWithError:]
 -[NSMapTable NSMapTable { } ] count underflow

The full stack trace is:

Fatal Exception: NSInternalInconsistencyException

Unfortunately, I don't have any steps to reproduce these, as I got them from Crashlytics.

Thank you,

We don't have any plans to fix this in 10.2.x. We made a number of changes to our networking stack in v100.0 and this was fixed as part of that larger effort. You can contact Esri Support to request a patch for 10.2.x but upgrading to v100 will probably be the fastest way to proceed

What's about 10.2.x branch? We don't want to migrate to 100.x so do you have plans to support 10.2.x?

It is fixed now in version 100.0.0, which was recently released in November.
