Getting "Class X is implemented in both": seems like PrivateFrameworks/BusinessChatService.framework defines the same classes as libPhoneNumberiOS

Hello 👋

I am experiencing random crashes when running tests on a framework that depends on libPhoneNumberiOS. Before the crash I see these lines on the log:

I am not sure what conclusion to extract from this. Is apple depending on libPhoneNumberiOS for their private frameworks? Is anybody experiencing the same? Thanks!

Using libPhoneNumberiOS 0.9.15

@paween your feedback would be very much appreciated, I run out of ideas with this one 😞

just wanted to chime in that we're experiencing the same warning. However, it isn't causing any crashes--it is just printing that warning in the console.

For me it is flaky and crashing very few times, only detected because I run the related tests many times as part of a CI job for flaky test detection. The print I think only happens when crashing, otherwise I see no print at all and code tests green
