For those who don't watch the video to know what components Apple has mentioned in the video to partially/fully rewritten to Swift:

* Many parts of Music app * Many parts of the Dock (rewrote Mission Control, accessibility features, etc) * Console App new features (e.g. logging) * Many OS Agents/Daemons * The new picture-in-picture feature in Sierra * Xcode features like the new documentation feature * New Playground app

Did swift gain 32 bit runtime support, or did the orphaned hardware models include the last of the 32 bit CPUs?

32-bit processors were dropped a while ago, by Mountain Lion if I remember correctly.

32 bit ARM has been supported from the start. As others have mentioned the 32bit Intel Macs do not support the latest OS versions anyway.

32 bit apps still run on macOS
