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.

iOS Dev Directory
Do you write or publish content about iOS development? Add your website to the iOS Dev Directory by Dave Verwer. Many newsletters (including SwiftLee Weekly) from the community use it for curation, so this is a must for extra reach.
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!
Xcode 26 Compilation Cache
Did you know Xcode 26 introduced Compilation caching? Artem Mirzabekian explains how it works and how you can benefit.

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:
SwiftUI Agent Skill Swift Concurrency Agent Skill
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!
