We have some Firebase crashes tracked in Crashlytics:
-[FPRScreenTraceTracker stopScreenTraceForViewController:currentTotalFrames:currentFrozenFrames:currentSlowFrames:]

Some in -[FPRCounterList counters]. I think they are related:

We have not seen it in our own testing, only saw the Crashlytics reports. They happen with iOS 9 and 10 only, with all device types (iPhone, iPod Touch and iPad)

[johnqh]

btw, this happened with Firebase 5.0 too, but didn't happen with 4.X. 4.X has its own different random crashes in iOS9 only but those crashes are gone. 95% of the crashes in 5.0 are one of those two

[eshiehz]

We're aware of the issue and a fix will be available in the next release. Thanks for filing!

[johnqh]

I see 5.3.0 in releases 7 days ago, but cocoa pod still only installs 5.1.0.

[paulb777]

@johnqh The 5.3.0 milestone still being open indicates we are still stabilizing and haven't published yet. It should be soon.

5.2.0 is available now though. Possibly you need to add the --repo-update option to the pod install command.

This bug is present also in 5.2.0

[alihen]

@zeqinjie, this should have been resolved in 5.3.0 - please update your pod if possible 👍

[zeqinjie]

ok, thx

[zeqinjie]

@alihen but when i update to 5.4.0 or 5.3.0.it will crash in iOS8.iussue
