THIS WEEK'S BLOG POST

​9 months of a Swift Concurrency Course​

March this year, I launched the Swift Concurrency course. It developed way faster than I expected, mostly due to the many changes we got during WWDC. In this article, I'm reflecing on 9-months of publishing concurrency lessons.

Primary reason for writing this article: I'm doing a pricing research.
I want the course to be more accessible to everyone, so I'm conducting this short pricing research. Can you help me get better pricing-per-country?

​Fastlane alternative - Codemagic CLI tools​

Are you tired of Ruby and Fastlane installation issues? There's got to be a better way! Discover Codemagic open source CLI tools. It is not a drop-in replacement for all of what Fastlane does (screenshots for example), but we use it at Codemagic to build and publish iOS and Android apps, also versioning and device provisioning.

WHAT I'M WORKING ON

Launching "From App Idea to 10K MRR" soon!

I'm super excited to share the trailer of my new YouTube series:

I'm actually already working on the app idea and it has boosted my energy. It's so much fun to work on a new app, and it's also been a while since I developed for iOS.

The journey will be a honest documentation of the challenges I'll be facing. It's also a unique look into my process of developing apps:

  • How do I decide on the app idea to build?
  • How do I find the right target audience?
  • Will I be able to get 10K Monthly Recurring Revenue?

I'm honestly not even sure if I'll be able to make it to 10K MRR, but that's not the goal of the series. In fact, I would argue there are more lessons learned if I don't make it:

  • How do I handle that disappointment?
  • I know I won't give up, so what would I do to still make it a success?

It will be a journey of challenges and learnings, and a journey in which I'll put everything I've learned into practice.
