Unclear if Apple will allow this in the store

edit: Yes I know you can build apps before they're in the store

It is permitted on the App Store. The developer had a thread on the fediverse several days ago.

As long as it's open source, you can sideload onto any iOS device by building it yourself.

Iff you pay an annual $100 dev fee.

Yes I know you can technically do this without a paid dev account, but it's practically useless because it has to be re-done every 7 days.

Surely considering the fact that you are streaming your Mac to Apple Vision Pro you should be able to easily resign it on that very device? :)

I don't know about you, but there's nothing easy about having to boot up an IDE every 7 days to sign and re-install an app you depend on. It's just one more thing to worry about and mentally keep on top of, the opposite to Apple's convenience and smooth UX ethos.

The visionOS side of this, which is the one that requires App Review, is a glorified VNC app. They will probably review it thoroughly but it doesn't seem like it breaks any rules.
