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.

Answer 1 · 2024-01-02T10:19:17.000Z

Could you please try with 4.0.3?

Answer 2 · 2024-01-03T02:15:19.000Z

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.

Answer 3 · 2024-01-07T20:52:57.000Z

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

Answer 4 · 2024-01-07T21:05:21.000Z

@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 (CocoaPods/Specs@a8228f9), but not TwilioConversationsClient 4.0.3.

Could it be a CocoaPods trunk deploy issue?

Answer 5 · 2024-01-09T11:08:44.000Z

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

Answer 6 · 2024-03-07T19:22:15.000Z

@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?

Answer 7 · 2024-03-10T05:57:37.000Z

@aeioliu it was multithreading race.
