### Mention any other details that might be useful

Encountered the same issue in both a direct integration into the chat project and when using the Microsoft-provided example project [link](https://github.com/Azure-Samples/communication-services-ios-quickstarts/tree/main/add-chat-push-notifications). The issue appears to be related to the AzureCore dependency, and a possible solution was suggested in the Apple Developer Forums [link](https://developer.apple.com/forums/thread/685369), recommending the use of @available(iOSApplicationExtension, unavailable). This change may need to be implemented in the Azure SDK to resolve the issue.
