I’m currently trying to fully understand category theory as it applies to programming. I’m not scared of math, however, I’m also not a mathematician, so I’m looking for an introduction that helps me build intuitive understanding first, and then goes all the way into the formalisms.

Here are the resources I am currently reading that I found the most helpful so far:

Why Category Theory Matters • rs.io

Quick intro on why it's useful and lots of links to resources of applications of category theory.

At WWDC 2019 Apple released some videos directly online, with no corresponding live session. This is a list of those videos with links to the video pages.

Some sessions were presented during WWDC but then split into multiple videos when posted online. This list includes the online versions, since they don't appear in the WWDC schedule. For example WWDC included session 711, "Introducing Combine and Advances in Foundation". This was split into two online videos-- 722, "Introducing Combine", and 723, "Advances in Foundation". Both 722 and 723 are included here.

GH Actions workflow for Mac and Vision Pro

This is taken from my app koja.works, as an attempt to get full notarized + appstore builds made in a single CI workflow so that I can keep track of all moving parts, without involving Fastlane (which in my experience breaks way too often due to system rubies etc).

Builds for both Mac and visionOS, and the vision file is probably easily extensible to iOS as well (maybe with matrix builds?)

I'm using a self-hosted Mac mini on my desktop, which is why I have to fiddle with PATH etc. I'm doing this because I require metal support during build, which Xcode Cloud does not support.
