iOS 15 breaks this Application

[rtatkins]

While the application does not error out, When choosing to send link via email, message or teams, only the keyboard appears, it is not possible to share the link. Additionally, this repo is using code that several methods are depreciated - modifyRecordsCOmpletionBlock, fetchRecordZoneChangesCompletionBlock for example. https://highstrungpro.com/wp-content/uploads/Screen-Shot-2021-10-22-at-8.55.37-AM.png please fix

I managed to find a way to fix that issue. But I don't understand it, so not submitting a pull request.
