I left a job as a chemist at the the age of 41 (with family & 3 kids) in order to start in iOS development a few years ago. I got a job as a junior software developer that did not pay a lot, and like you, no one was interested in anything I had out on GitHub, nor an app I was working other than the fact it showed I probably had actually written some iOS code. But I was confident then as you should be now, that if I stuck around and pursued improving my skills as I worked over the next few years, I’d become a valuable asset that lots of employers would gladly hire. In fact, I did. I eventually had recruiters contacting me! There’s a lot to learn and it simply takes time and a commitment to doing good work. If you are excited about programming, then it’s a bit like a dream come true, that is getting rewarded for working hard.
