I have started receiving details of a crash that I have not seen before, and it only appears to have started happening since the 7.1 update.
The exact line from the stack is :
CFNetwork
___ZN14CoreStreamBase34_streamSetEventAndScheduleDeliveryEmh_block_invoke + 30
and the entire trace is here:

Has anyone else experienced issues with this? I have been over to the AFN github but cant see anyone else reporting this issue.
Thanks

As per your question, you need to install fabric or firebase crashlytics in your app. It will help you to debug the crash issue.
Here is the link for fabric: https://fabric.io/kits/ios/crashlytics/install

The crash is caused SIGSEGV in objc_msgSend. This means you have tried to access invalid object address. This means there a some issue related to memory in app.
This problem mostly faced while you do delete or any operation on UITableView
Solution
You can find using your Analyze of xcode and fix all warning that they displayed to you.
Also You can track this using enable zoombie and Instrument tool in xcode .

How can I find and fix issues like this (the ones that don't seem to have anything to do with self written code)?

my log help~
This crash report is really tough for me to get a handle on. I've seen it every now and then, and its been pretty impossible to fix given that it doesn't really give me any references to my code to work from.
Is this a crash that was caused by Apple and I don't have to worry about it?

This is not caused by apple. Below line is the entry point of the crash. Make sure some related object/view doesn't get deallocated.
MyApp 0x0003f7b5 +[AFURLConnectionOperation networkRequestThreadEntryPoint:] (AFURLConnectionOperation.m:161
Update:
I take back my object deallocation statement. I doubt this crash might happen due to UI element being created\updated in background thread. I mean an UI element created/updated in the network callback method.
The solution to the problem would be adding a dispatch_async in main_queue to perform the UI updates.
