the reason mods will never be able to be put on the apple appstore is because
1: Luni doesn't want mods on any appstore, although he's okay with itch.io. We can't upload the mods to apple as it would be copyright infringement.
2: It costs $99 per year to keep the app on the store.
3: In order for the app to even work, I believe you'd need to use a special coding software, and I don't think people who make mods use it.
