One announcement from WWDC that didn’t get much fanfare was a rule change concerning virtual currencies. From the App Store review guidelines:

Apps may facilitate transmission of approved virtual currencies provided that they do so in compliance with all state and federal laws for the territories in which the app functions

This rule change opened the door to the return of bitcoin to the App Store in the form of the Coin Pocket app. From coindesk.com:

Apple is making good on its recent bitcoin policy shift, with a new bitcoin wallet app appearing for download in the iOS App Store.

The ‘Coinpocket’ app is described by its developer as a wrapper for a previously available open source HTML5 version, this time with full access to the camera hardware for QR code scanning.
