Freehand Drawing

Yesterday my last post on the series ‘Let’s build Freehand Drawing for iOS’ has been published at Badoo Tech blog. It’s been a very good experience for me, and of course I recommend you visit the tutorials if you are interested.

I divided the tutorials in 3 parts:

  • Part 1: Introduces the feature and a naive implementation
  • Part 2: Adds undo functionality, refactoring along the way
  • Part 3: Improves stroke to make it look smoother

Building tutorials is hard

This series has been my first take on writing technical tutorials. And I must say that it’s a lot harder than I thought. You need to keep track of the content, code correctness, and the pace of the articles so it’s readable and understandable. Coding while writing an article is challenging, but the experience has been very gratifying.

I also get to brag about something I was really happy to build for the Bumble project. So I think I’ll definitely write other tutorials in the future.
