Update recommended prior to iOS 18.1 general availability

[Kyle-Reis]

The iOS 18.1 Beta 5 release contained a breaking change which impacts the iOS Intune SDK's ability to block the iOS 18 writing tools feature when app protection policy is configured to restrict outgoing data transfer. This issue has been addressed in the 19.7.1 release for Xcode 15 and the 20.1.2 release for Xcode 16. We recommend that all users of the Intune App Wrapping Tool for iOS rewrap their application with the latest available supported release which corresponds to the Xcode version your application is currently compiled with, and that you push your updated application to production as soon as possible to ensure the fix for this issue is available before iOS 18.1 becomes generally available. If you have any questions, please file an issue in this repository or reply directly to this announcement.
