I have written a dozen or more files on Swift-related topics and put them on github here. I like markdown, it's easy and portable and it works well on github, which is also easy. I've been using the MacDown editor. I like it too.
The stuff I like the best is a detailed look at libraries and frameworks on macOS, which got big enough that I broke it out into another repository here.
I haven't posted regularly on blogger in 4 1/2 years. People still come by. My Swift posts from Dec 2015 have about 1100 page views, and those from last week more than 70. I hope that at least one person finds value in one of these posts. That would be enough for me.
I know there is stuff on the site that is broken or outdated. If you would like to revisit a topic, please let me know in a comment.
