Driver's license category B

I've started developing simple programs in AppleSoft Basic since the age of 6 on my father’s Apple II Plus. In 2001, with the release of Mac OSX, I've started writing simple applications in Objective C. In 2010 I've developed my first iPhone App “Quiz Patente B” (Italian driving licence test questions app): “Quiz Patente B” has immediately jumped to the first place of Top 100 Paid Apps in the Italian App Store for Education category and has remained in the Top 10 for more then one year. “Quiz Patente B” has been awarded as Best Italian App 2011 in the Education Category by macitynet.it, the most important Apple & Hi-Tech News and Reviews Italian site. I've published more than 25 apps on the App Store, including “Fotometka” a fully-featured Social Network with a back-end developed in PHP and MySQL. With the release of Swift 5.1 I've started the migration of my applications to Swift.
