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.

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

http://rs.io/why-category-theory-matters/

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

libdispatch efficiency tips

The libdispatch is one of the most misused API due to the way it was presented to us when it was introduced and for many years after that, and due to the confusing documentation and API. This page is a compilation of important things to know if you're going to use this library. Many references are available at the end of this document pointing to comments from Apple's very own libdispatch maintainer (Pierre Habouzit).

My take-aways are:

• You should create very few, long-lived, well-defined queues. These queues should be seen as execution contexts in your program (gui, background work, ...) that benefit from executing in parallel. An important thing to note is that if these queues are all active at once, you will get as many threads running. In most apps, you probably do not need to create more than 3 or 4 queues.

• Go serial first, and as you find performance bottle necks, measure why, and if concurrency helps, apply with care, always validating under system pressure. Reuse
