how to fix this issues?

Answered by DTS Engineer in 731940022

The above indicates:

  • It’s a bug.

  • It’s reported as fixed in iOS 16.1 beta.

  • The workaround is to limit your app to a single subscriber.

What “further analysis” are you looking for?

We have the same crash

Interesting.

Any chance you can post a full crash report as well? The crash report from rbbtsn0w is a bit weird — it looks like some of the symbols in their code were deliberately obfuscated — and I might be able to learn more from a second report.

The immediate cause of this crash is pretty easy to understand. Consider this backtrace:

0 CoreFoundation  … __exceptionPreprocess + 164 …
1 libobjc.A.dylib … objc_exception_throw + 60 …
2 CoreFoundation  … __NSFastEnumerationMutationHandler + 116 …
3 Foundation      … -[NSConcreteHashTable countByEnumeratingWithState:objects:count:] + 76 …
4 MetricKit       … -[MXMetricManager deliverMetricPayload:] + 408 …
5 Foundation      … __NSXPCCONNECTION_IS_CALLING_OUT_TO_EXPORTED_OBJECT_S1__ + 16 …

Frame 5 is XPC delivering a message to MetricKit. That message contains MXMetricPayload values. MetricKit is in the process of iterating through its array of subscribers, passing that array to the -didReceiveMetricPayloads: method of each subscribers.

Frame 3 through 0 are characteristic of the was mutated while being enumerated exception discussed above. It’s likely that the collection in this case is MetricKit’s set of subscribers. So, you get this crash because you have either added or removed a subscriber while MetricKit is in the process of delivering metrics to its list of subscribers.

I’m not a deeply familiar with the MetricKit source code but this sounds like a bug to me. AFAICT MetricKit has appropriate serialisation for the APIs to add and remove subscribers, but not for its own internal use of the subscriber list.

I encourage you to file a bug about this, make sure to include a crash report. If you are able to reproduce this in your office, take a sysdiagnose log immediately after the crash and add that as well.

Please post your bug number, just for the record.

As to a workaround, how many subscribers does your app register? That is, if you set a symbolic breakpoint on -[MXMetricManager addSubscriber:], how many times is it called on launch?

I confirmed that [MXMetricManager addSubscriber] is called twice - it's invoked from another internal swift framework. Should there be only one subscriber? We had to remove a subscriber and release a version to stop the influx of crashes.

I submitted a bug using Feedback Assistant: https://feedbackassistant.apple.com/feedback/11525011

I see that it says "Potential fix identified - For a future OS update"

I confirmed that [MXMetricManager addSubscriber] is called twice - it's invoked from another internal swift framework.

Cool.

Should there be only one subscriber?

No. This is definitely our bug to fix.

We had to remove a subscriber and release a version to stop the influx of crashes.

That’s the correct workaround until we fix the bug.

I submitted a bug using Feedback Assistant [FB11525011]

Thanks!

My reading of that bug is that the fix is included in the current iOS 16.1b3 (20B5056e) seed. If you can find a way to reproduce this on 16.0, you could try testing with the beta seed to see if it still reproduces for you there.

Accepted Answer

The above indicates:

  • It’s a bug.

  • It’s reported as fixed in iOS 16.1 beta.

  • The workaround is to limit your app to a single subscriber.

What “further analysis” are you looking for?

I finally find my way to solve this problem, first share my analysis of this problem: when deliver Metric payloads to all subscribers we called -[MXMetricManager addSubscriber:], this cause the NSConcreteHashTable that save subscribers get mutated while being enumerated. It seems that the NSConcreteHashTable add subscribers or deliver Metric payloads in it's own thread, so just dispatch to main queue to call -[MXMetricManager addSubscriber:] not work. This is easy to reproduce, just keep add new subscriber(not equal to existed subscriber) in you code and simulate metric payload with Xcode. Finally I try to hook -[MXMetricManager addSubscriber:] and -[MXMetricManager removeSubscriber:] to a custom Class, this class hold a NSPointerArray of all subscribers, and dispatch to each subscribers when -didReceiveMetricPayloads: and -didReceiveDiagnosticPayloads: getting called.
