Are you tired of Ruby and Fastlane installation issues? There's got to be a better way! Discover Codemagic open source CLI tools.

Xcode Migrations: From Stone Age to AI Mastery
As an indie developer, it’s easy to migrate to a new Xcode release. For larger teams, however, it can be quite the challenge. It took Qonto several weeks to apply the enhancements. P.S., they’ve also been using RocketSim for years to enhance their team’s productivity!
Debugging Swift Concurrency: "Am I on the Main Actor?" (Not the Main Thread)
Thread.current and Thread.isMainThread don’t work with Swift Concurrency, so what do you do instead? This article explains.
Treating Warnings As Errors In Swift Packages

What I'm working on
Concurrency Videos and Pragma Conference
Conference season is around the corner and allows you to visit great talks around the world. Unlike other years, I'm taking it easy this year. I'm so far only scheduled for Pragma Conference where I'll give a talk on Swift Concurrency.
I love win-wins, so while preparing the talk, I'll also record new videos for my concurrency course. To make it a win-win-win, I'll also use the materials to produce some key concept videos for YouTube. Time spent well!
If you're working on side projects while having a full time job, you'll love the win-wins. They've been crucial in my growth while I was working at WeTransfer back in the days. It's also why all my products (blog, newsletter, courses, RocketSim) target the same audience: developers. I only have to build an audience once and I can benefit from growth for all products.
This insight could open your eyes and if it does, I'm sure you'll enjoy more of my tips at going-indie.com.
Meanwhile, we're getting closer to the final release of macOS Tahoe, iOS, iPadOS, etc. Apple announced a special event for the 9th of September which will likely announce the final release dates, too. Make sure to finish your redesign and new API adoptions!
