AwsCommonRuntimeKit.cleanUp() hangs after calling Auth APIs (signUp) about aws-crt-swift HOT 4 CLOSED

AwsCommonRuntime.cleanUp() awaits all threads to join to ensure everything is cleaned up. If there are any Swift object keeping a reference to CRT resources like HostResolver, it will keep waiting for it to release so that it can finish the clean-up. Cleanup is an opt-in feature if someone wants to make sure everything gets cleaned up and there aren’t any memory leaks at the end of application.

I would suggest updating to latest version of crt-swift as we have fixed a lot of memory leaks and reference cycles which might also be causing an issue.

Just a quick update - still seeing this issue after updating to Swift SDK 0.6.1 with CRT version 0.4.0.

@thisisabhash Hi,

I have updated the docs to explain the cleanup behavior. It is an optional feature to make sure that there are no resources alive at the end. It is expected to hang if there is any resource still holding reference to CRT resource. You do not need to call cleanup normally and the Swift SDK never calls cleanup.

Also, some reference cycles bugs were fixed in CRT version 0.5.0, so that might cause an issue with cleanup if there are no CRT resources held before calling cleanup.

Thank you for the confirmation. Will remove the call to this optional feature.
