I’ve seen some conflicting reports, but I’m curious - as of today (4.14.2) - if this is something that’s mostly achievable without a lot of development expertise. I guess with that, even if I use UE4, would I still need a mac to deploy something onto an iOS device?
Any resources (learning or otherwise) would be hugely appreciated. Thank you
I’m also curious! 
As far as I know, yes you do. What I do is I make my Google Cardboard project at Windows, and when it’s ready to package, I use remote build for Mac to package on Windows.
It is possible to package iOs on Windows, but this is purely for development. But if you want to use the GoogleVR plugin, you would need Mac for development already as well, so with remote build.
