Yes! Apple has come to its senses and brought the compact tab bar back

On the web I'm really pleased to see codea.io working hard

ChatGPT also makes the list

The top app referrer for Codea is ChatGPT

I also quite like Liquid Glass (though implementing it at scale has not been fun).

The people most against Liquid Glass are the people who are really afraid of macOS becoming more closely aligned with iOS and iPadOS, which is perhaps why they're overindexing on the little things and silly, fixable bugs instead of talking about the larger picture — the Mac is evolving to serve a different audience makeup (wait for the Neo effect), and some people are simply going to be left behind

It's long, but only because it makes so many brilliantly insightful points. I thought I remembered these points being spread across at least three different articles, but they were all in this one

We've been adding MCP and agent support to Codea. Asked Codex to create a What's New animation for it in SwiftUI

UIDocument in macOS Catalyst question: if users open documents from arbitrary Finder locations, is restoring those documents on next app launch supposed to require so much ceremony?

I’m finding I need security-scoped bookmarks plus regenerating the restoration NSUserActivity/bookmark after document saves, otherwise previously opened external documents fail to reopen on relaunch

Feels more complex than I expected

Something I was kind of putting off for the macOS version of Codea was changing the autocomplete suggestions from a bar to something more traditional

I asked Codex to have a go at it. It did a good job. I took over and made sure I agreed with (or changed) its decisions, and added some polish

Not sure if it saved time, but I never would have started without being able to generate the "rough draft" so quickly
