THIS WEEK'S BLOG POST

​Agentic Development: Multi-Project Challenges​

Using agents for development is great, but I've also learned the hard way that it can cause trouble: goals not reached, mentally overloaded, and the feeling of endless possibilities.

If you don't manage your agents well, you'll regret in only weeks from now.

​Avoid Spacers in SwiftUI Stacks​

Did you know this side effect of using a Spacer inside a SwiftUI stack? Pavel Zak explains what I mean.

​Learning to develop more accessible iOS games​

It’s funny how someone that I see as an accessibility expert mentions “learn from actual experts”. Daniel Devesa Derksen-Staats describes his first approach to making his game more accessible.

​SwiftUI transitions with distortion effect and Metal Shaders​

You know you’re in for a treat if you combine metal shaders and distortion effects for a SwiftUI transition. Pavel Zak created an article with videos for each step. While it's an older article, I still found it an interesting read!

SwiftLee GIVEAWAY

​Win a ticket for iOSKonf​

Conferences changed my iOS career more than any tutorial ever did

  • Meeting developers from the community
  • Learning from in-depth talks

That’s why I’m extra happy to giveaway a free iOSKonf ticket. I’ll be speaking there and would love to meet you!

WHAT I'M WORKING ON

Conference Season

It's the time of the year before summer where many conferences take place. Last Friday, I spoke at AppDevCon, and next week I'll by flying to speak in Shanghai for Let's Vision 2026. (Let me know if you want to go, I can give you a ticket discount!)

Towards those conferences, it's busier than normal. I need to prepare my talks, while also doing normal day-to-day tasks I set for myself. Normally, I'd reuse talks at multiple conferences, but I'll be giving a brand new talk at Let's Vision: What 15 Years of Coding Didn’t Prepare Me For: Agent-Driven Development.

I aim to bundle all my learnings so far in a journey-telling talk format. This week's article shows a sneak peek into what I'll share. It's an exciting topic, highly relevant to my daily development.

At the same time, I've been updating my Agent Skills:

Both skills are full of knowledge and they're now optimized for much better token usage. The net result is ~4,000+ fewer tokens read per typical agent query through smarter routing, with zero loss in knowledge depth. You can read more about this change on Twitter or LinkedIn.
​
Enjoy!
