I spent entire day figuring out what's going on with Crashlytics and my app. It detects fatal events when I crash my app, but not activating crashlytics section for the app.

Not detecting app

It's not detecting the app, but it does detect crash events:

Events

Here is the log:

My guess it's related to:

Expected encodable string, but found NSNull instead. Set a symbolic breakpoint at FIRCLSEncodeString to debug.

When I set a breakpoint there, in debugger I see a string, but once the string passed to the FIRCLSEncodeString function it becomes nil

No idea what could cause it.

Any ideas?

crashlytics ios
1 Answers

I found what caused it. My app didn't have display name and string version in the target settings, it caused the Crashlytics to print Expected encodable string, but found NSNull instead and eventually not sending the report. I had to disable all optimizations in order to debug it.
