FIX: uncaught exception from unsafe array access #56

Closed Coding-Solo closed 6 months ago

Coding-Solo commented 6 months ago

Fixes an issue where repeatedly signing in and out can sometimes cause providerData to not have any items within the array, causing the app to crash with:

Terminating app due to uncaught exception 'NSRangeException', reason: '*

This is a safety check to prevent that from happening.
