THIS WEEK'S BLOG POST

​MainActorMessage & AsyncMessage: Concurrency-safe notifications​

A few warnings were hard to get rid off when migrating to strict concurrency. One of those were notifications, which are tightly connected to GCD dispatch queues. With the new API discussed in this article, you'll be able to post and observe notifications on specific isolation domains.

SWIFT EVOLUTION

WHAT I'M WORKING ON

I'm going to build a new app!

For those who know me, I don't often start a new app project. I truly believe in focus, and a new app distracts me from all the things I already do.

Last week, I've enjoyed quality time with my family. We took a week off, stepping out of the weekly rhytm. Doing so often sparks creativity and a fresh mind.

The latter resulted in a new concept, which I'll publish across YouTube and SwiftLee:

"From App Idea to 10K MRR" — A new YouTube Series

The concept is simple: I'll work in public, building an app that makes 10K. But that's not all: I want to show insights into how I work, how I make decisions, and what I believe is the best way to make an app successful.

It feels like a concept that compounds all I know:

  • Learnings from my www.going-indie.com course
  • I can demonstrate development & debugging skills
  • I'll be creating new YouTube content along the way

Effectively, I'll be spending as much time on content as before, but with a clear purpose. The result is a new app, new income revenue, and a unique insight into indie app development.

I'm already working on the first episodes, where I'll be inviting community experts to give me quality hints, tips, and tricks. If you don't want to miss out on this series, subscribe to my YouTube channel.

UNTIL NEXT TIME
