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.
