Back in Feb 2013, I started my journey of exploring and learning iOS development. It was very interesting experience for me. I love and do programming since I was 12 years old. It was a great way to enjoy my spare time in something useful. Back to that time, I used to play games and use some educational programs on my MSX computer. It had only 64 KB RAM, and we used to load programs either by the cassette tape player, or the expensive cartridge (it was simply a programmed ROM module). It was fascinating experience for me when I started learning MSX BASIC language and started to write very simple programs. 20 years later, I felt the same fascinating experience when I wrote very simple programs for my iPhone and had it running on my device!
