Thanks for the crash report.

Unfortunately there’s no obvious smoking gun here. My best guess is that this is a bug in CFNetwork. It seems to affect a wide variety of apps across a wide range of OS releases.

How reproducible is this for you?

Also, I can’t guarantee that this crash is the same crash that Tujie is talking about at the start of this thread. The issue is that their crash report is badly symbolicated. Consider this:

Crashed: com.apple.NSURLSession-work
0  CFNetwork                      0x18578 CFURLRequestSetURL + 14416

That offset, +14416, is way too large for the address to actually be within CFURLRequestSetURL, and without a full Apple crash report I can’t resymbolicate in order to find the right symbol.

Understood. But my question was:

Are you able to trigger this in your office at all?

Hi, Did you find Any solution for this? we see this crash a lot lately.

This problem still exists in my App and I haven't found a solution yet

This problem still exists in my App

Which problem specifically? If you’re seeing crashes in CFURLRequestSetURL but with a huge offset, that could be caused by a wide variety of problems that all look like the same problem because of wonky symbolication (see my comments here).

If you have an Apple crash report, please post it here, using the advice in Posting a Crash Report.
