Thank you for your contribution, just some changes.

I've added in a fix for the SelectUserViewModel. When I was on the user selection page, I would click on the button for my user and it would do nothing. After following the flow with logging I found that the message just stopped when sending back via that events publisher.

Removing .receive(on: RunLoop.main) made it work. I'm not really sure why, something to do with the scheduling. I'm obviously new to Swift, let me know if that was the wrong thing to do. Once I removed it I was able to login and do the rest of the actions in the tvOS app.

I got the "solution" from here - https://forums.swift.org/t/combine-receive-on-runloop-main-loses-sent-value-how-can-i-make-it-work/28631/24
