Closed aryo closed 6 months ago

aryo commented 7 months ago

SDK version

4.0.2

Device model

iPhone & iPad, various models

OS version

iOS 16.5 - 17.2

Issue description

We've been getting a boat load of these crashes throughout various iOS versions and iPhone makes and models.

Have you guys seen this specific crash before? I can attach some more stack traces if needed.

Example stack traces

OS Version: iOS 17.0.3 (21A360)
Report Version: 104

Exception Type: EXC_CRASH (SIGABRT)
Crashed Thread: 28

Application Specific Information:
Object 0x28123bd20 of class TwilsockTransport deallocated with non-zero retain count 2. This object's deinit, or something called from it, may have created a strong reference to self which outlived deinit, resulting in a dangling reference.

berkus commented 6 months ago

Could you please try with 4.0.3?

aryo commented 6 months ago

We just released a new version today that has 4.0.3.. will post an update within the next couple days or so as people upgrade.

aryo commented 6 months ago

So far it's been almost a week without this crash, so I will close this issue.

aryo commented 6 months ago

@berkus Just on a slightly unrelated note.. have you guys stopped publishing to CocoaPods? I can see on the same release day for 4.0.3 that its dep TwilioTwilSockLib 2.0.4 was published (https://github.com/CocoaPods/Specs/commit/a8228f90d2251c8eb8b3920693ad0c4dab38dd09), but not TwilioConversationsClient 4.0.3.

Could it be a CocoaPods trunk deploy issue?

berkus commented 6 months ago

@aryo yep, we switched to SPM distribution only at the moment.

aeioliu commented 4 months ago

@berkus long shot but we're seeing a lot of these errors but with _DictionaryStorage getting deallocated with a non-zero retain count. this is the only reference to this sort of error on the web. do you remember what the issue here was that you fixed?

berkus commented 4 months ago

@aeioliu it was multithreading race.
