I was developing stuff to be shown inside the headset that wouldn't have worked in the simulator, so I was frequently using the headset regardless. It was often easier to just leave it on and develop than constantly put it on and take it off to test things out.
As for development of non-VR stuff I personally didn't because I already had a fully-featured desk setup and the OS at the time was buggy enough to not want to deal with it (as every OS is years before release, not a ding on Vision Pro at all). With a good OS (which it will be upon release) and more native apps (like Termius on iPad) I definitely would though!
Do you think it’ll allow Xcode for development? When you say you were wearing it while doing dev work were you pairing it with a MacBook? From what I understand the OS is more similar to iPadOS (no Xcode, ability to compile binaries) vs MacOS.
I honestly don't know that will be supported on the final version, but what I was referring to was developing on a Mac through the Vision Pro and deploying to the Vision Pro.
FWIW the iPad supports dumbed down app development through Swift Playgrounds and presumably the Vision Pro will at the very least support that if it supports all iPad apps, but that's pure speculation.
