I started programming in the early 1980s and was an instant Mac fan as soon as I saw my first one.

When it became possible to write apps for the iPhone, I taught myself Objective-C and started to program for iOS and then for Mac OS X using Objective-C. As soon as Swift was announced, I realised that it would be the next great thing and started reading and learning as much as I could.

I write my own apps under the name TrozWare and blog (mainly about Swift) at http://troz.net

I love puzzles, reading (mainly fantasy & sci-fi) and talking about tech and programming.
