This page talks about building for IOS on Windows using blueprints only.
Question: Assuming I build my mobile project completely in blueprints, can I just copy that project to my Macbook and ship/package the game on that device using UE? is this still viable in UE5?
The short answer is, Yes.
You just need to have all the Xcode and iOS provisions and such setup on your Mac. In theory, this is easier than doing Remote Builds. However, you’ll be doing a lot of bouncing back and forth if you are developing on Windows and then coping over to a Mac every time you want to make a build to test something on a device.
