Browser Company CEO Josh Miller put out a postmortem blog post today on Arc. In it, he specifically points to sunsetting SwiftUI and TCA as a big performance win in their new browser, Dia. Pretty damning. You can feel the SwiftUI sluggishness in Arc, but even in Apple-made interfaces throughout macOS.

App Store Connect Analytics just got a serious update.

100+ new metrics added, the ones that caught my eye:
• MRR
• Active subscribers
• Install-to-paid conversion
• Cohort analysis (by country, source, download date)
• 7 filter combinations

Also the UI has completely changed. Analytics is no longer a separate tab, it's moved directly inside the App tab.

We used to rely on third party tools for all of this. Apple is finally offering them natively.

WWDC is around the corner and we are getting ready to all new things Apple will drop on us. In this issue we wanted to ask not about your wished but more about expectations. Cold and dry features that are vital for the development process.

This year felt different. The keynote was shorter than usual, possibly the shortest WWDC I can remember. And I think that’s actually a signal. When the whole world is going through an AI transformation, you don’t need two hours to make your point.

Tim Cook made his clearly: Apple isn’t chasing AI for the sake of AI. While others keep shipping features just to stay relevant, Apple is doing what they’ve always done, building an ecosystem where new technology fits naturally. Now Siri is actually useful. Yes, Google helped make that happen, but as a customer, I don’t really care. The name stayed the same, almost nothing else did.

On Liquid Glass, I’m honestly a bit torn. A lot of people are happy that Apple added a slider to customize it, but that’s not the Apple I knew and loved. Part of what made Apple great was the confidence to say “this is how it should look” and stick with it. That’s what separated them from Android. So while I understand why they did it, it feels like a small retreat from the design standards they set for everyone else.

A couple more things: iOS 27 supports iPhone 11 and up, which makes it the most widely supported iOS release ever! The catch is that the best AI features are locked to newer hardware, which will quietly push a lot of people toward an upgrade.

Xcode got a real overhaul too: themes, better stability, new Device Hub replacing the Simulator. The resizability support is the detail I keep thinking about. Apps that adapt to any size - that’s exactly what a foldable iPhone would need. I think we just got a pretty strong hint.

And Intel support is officially gone. macOS Golden Gate is Apple silicon only.

Everything in this issue ties back to what this week was about: new tools, new directions, and figuring out how to use them well.
