There's been talk about exploring porting the engine to iOS at the beginning of 2023 but AFAIK the current state of things was that it's a significant undertaking and probably not worth it just for the EU market.
But they do have mobile arm builds already don't they? Of course iOS is very different from Android but it's not like they'd have to do complete port. And it targets the same architecture that's in macs and they have builds for it obviously.
