iOS Newsletter #0: Refactoring Slow and Steady

This week's issue discusses the art of refactoring, improving Swift completion blocks,'s new app design, and an interesting account of Swift 3 migration pain. Check the "nuts and bolts" section if you're interested in Regular Expression stuff. I wasn't, but I didn't have a choice 😫.

Refactoring Slow and Steady

Rob Napier put out a good piece on refactoring in a production environment. Testing quickly comes to the fore, and rightly so. I loved the closing punchline: "go slow and steady and keep shipping".

Nuts and bolts

I ran across a few interesting tools this week and would like to highlight them. I haven't found a direct use for all of them yet, but I'm keeping them in mind.


Open-source micro-framework for observing file changes, both local and remote. Helpful in building developer tools by Krzysztof Zabłocki (krzysztofzablocki on GitHub).


"Sourcery scans your source code, applies your personal templates and generates Swift code for you, allowing you to use meta-programming techniques to save time and decrease potential mistakes." A code generation framework to help you get around Swift's static-ness, also by Krzysztof Zabłocki.

A brief tour of regular expressions

Had to ("been made to") dive more deeply into Regular Expressions than I was comfortable with, this week, and found this article particularly enlightening. As its title suggests, it takes you on a whirlwind tour of how regular expressions actually work. Along with the ever excellent, I was finally able to wrap my head around Regular Expressions enough to be mildly productive with them 😅.


Stagehand iOS game


Wasted quite a bit of time on this new take on Mario for iOS. You manipulate the environment instead of the character. Novel and cute.
