[BUG] Push Notifications: 'shared' is unavailable in application extensions for iOS: Use view controller based solutions where appropriate instead.

[mattials]

Describe the bug
Encountered the error message: "'shared' is unavailable in application extensions for iOS: Use view controller based solutions where appropriate instead." in ApplicationUtil.swift line 49 -> return UIApplication.shared

Exception or Stack Trace
'shared' is unavailable in application extensions for iOS: Use view controller based solutions where appropriate instead.

To Reproduce
Followed the Microsoft Azure tutorial link for integrating push notifications into a chat application.
Encountered the error message: "'shared' is unavailable in application extensions for iOS: Use view controller based solutions where appropriate instead."

Code Snippet
ApplicationUtil.swift line 49 -> return UIApplication.shared

Expected behavior
Successful compilation without errors on ./add-chat-push-notifications in xcode 15.

Screenshots

Setup (please complete the following information):

• OS: iOS 17.0.2
• IDE : xCode 15
• pod 'AzureCommunicationChat', '~> 1.3.3'

Additional context
Encountered the same issue in both a direct integration into the chat project and when using the Microsoft-provided example project link. The issue appears to be related to the AzureCore dependency, and a possible solution was suggested in the Apple Developer Forums link, recommending the use of @available(iOSApplicationExtension, unavailable). This change may need to be implemented in the Azure SDK to resolve the issue.
