Handling optional scalar Core Data attributes
Voodoo called @NSManaged is not always your friend
Hi, I‘m Aleksandar Vacić
I spent 15 years in web development, working from simple personal web pages up to enterprise-level sites. This blog has my web posts dating back to 2003.
I lost interest in web around ‘08 and was happy that iPhone appeared at the time to kickstart the Age of Mobile development.
In early 2012 I went full-time with iOS development through Radiant Tap after it was clear that iOS dev is perfect blend of my passions: user experience and efficiently crafted code.
Since then, almost all of the posts are iOS, Objective-C and – since autumn ‘16 – Swift related.

My work
I have created over 70 apps on the App Store, for myself and various clients. My best ones are proudly shown at Radiant Tap.
I offer teaching and on-site training as well as contract work under Standard and Enterprise programs. If you are interested — contact me today.
Community
I am co-organizer of the iOS Developers Srbija Meetup group and frequent speaker at our (rather) infrequent meetups.
