So @oskargroth pointed Claude and Hopper at SwiftUI to try to figure out what's going wrong with List performance, and it has a scathing take on the architecture it's discerned from the disassembly…

"this is the code of a team that's been debugging reuse failures for years. They've been patching and optimizing within the architecture rather than questioning whether the architecture is right for this use case."

(/via the site we don't talk about)

Hopper's MCP in something like Codex is *killer*. I can ask it things like, 'what private API could I use to make a UIKit window dockable on visionOS', and it will just figure it out from the disassembly, same way I would — just a lot faster.

Its solution matches the one I reverse-engineered myself a while back (https://github.com/steventroughtonsmith/VisionImmersiveDockableUIKit/blob/main/VisionImmersiveDockableUIKit/Source/Application/VVUDockableWindowScene.swift)

If the original Mac had used icons in menus from the start, nobody in their right mind would be calling for their removal today.

That's how you know that argument doesn't reflect reality. All major platforms now have icons in menus; you can't wind back the clock on that one, you're just obstinately refusing to follow the system standards and user expectation.

So much ink and many podcast hours have been wasted discussing the wrong parts of the issues with Liquid Glass on the Mac

If you want to get rid of the Liquid Glass sidebar window design, apply .containerBackground(.white, for: .navigation) to its content.

Hundreds of hours and thousands of words to understand and fix a crappy Bonjour implementation. This was a helluva rabbit hole.

If you have a Canon printer that's constantly going “Offline”, you’ll want to read this:

Over the last few days I shipped 2 major features for http://thecommander.app that would shock the pants off 99% of Electron apps out there:

1. Multiple windows – I just love it. I can keep all sessions in tabs or separate windows and lay out my work on the desktop however I want. #macos #macdev #agentic

2. UI session restoration – this feels so natural. I can close the app and relaunch it at the exact moment where I left off.
