[CR] feat: iOS build

[sonphantrung]

Summary

None

Purpose of change

1. I want to play DDA on my iPhone
2. The ones provided on the App Store are outdated and I can't afford as I'm broke
3. I want to have an easier way of compiling iOS builds

Describe the solution

This is a sequel of @smileynet's #61550 (attribution will be added later). Additionally:

• I have fixed some "angled" includes
• I aimed for feature parity with Android. To achieve this, I utilized Swift's fairly new C++ interop feature for exposing vars to existing code

Describe alternatives you've considered

Play on PC 😢

Testing

Additional context

Compared to compiling Mindustry/Shattered Pixel Dungeon, this thing is far tougher for a person not having a Mac like me. Any helps are appreciated!

Compiled (albeit having problems)

OK, so now I'm having this problem when compiling:

How is this error supposed to happen?????? It's defined in input_context.h w/ correctly added ifdefs!

In your build, will it have support for ipads with keyboards? Thanks!

TBF, it should, as SDL have done most of the heavy-lifting already, but I don't know whether the key repeat bug still exists nowadays.

Cool. That's good to know. Also, on Yuri Apollov's app, every time you press Enter or ESC, it has a chance to fire twice and it's really irritating, making the game nearly unplayable. This started when I updated to iPadOS 17 and I've seen no bug reports on the internet.
