I've scrolled through the site wondering who the author was, I have completely abandoned the iOS/Swift world now, and wondering how you could still make money with iOS books/tutorials considering the huge number of options (where popularity usually inversely correlate with quality) you have.

Then I saw "jordanmorgan10" :). For those who don't know, Jordan has been very active in this space for years, I remember him from the early days of Swift, it has not been an overnight success.
