With the announcement of Apple’s Project Catalyst (aka UIkit) will the Unreal Engine be ported to iPadOS?
UIKit/Catalyst probably will have no effect on Unreal Engine app development, you’re making stuff with the Unreal Editor and that may convert things in a way to take advantage of native api’s but that won’t be something that’s apparent in how you develop something with UE.
As far as iPadOS goes, it probably won’t effect things much, it’s more of OS features than something for apps specifically.
