swift-evolution VS KorGE

[A Vision for Embedded Swift](https://github.com/apple/swift-evolution/blob/main/visions/e...) has the details on this new build mode and is quite interesting.

> Effectively, there will be two bottom layers of Swift, and the lower one, “non-allocating” Embedded Swift, will necessarily be a more restricted compilation mode (e.g. classes will be disallowed as they fundamentally require heap allocations) and likely to be used only in very specialized use cases. “Allocating” Embedded Swift should allow classes and other language facilities that rely on the heap (e.g. indirect enums).

Also, this seems to maybe hint at the Swift runtime eventually being reimplemented in non-allocating Embedded Swift rather than the C++ (?) that it uses now:

> The Swift runtime APIs will be provided as an implementation that’s optimized for small codesize and will be available as a static library in the toolchain for common CPU architectures. Interestingly, it’s possible to write that implementation in “non-allocating” Baremetal Swift.

I may be out of my depth here as I've only casually used Rust, but this seems similar to Swift's proposed lifetime dependencies[1]. They're not in the type system formally so maybe they're closer to poloneius work

Swift recently adopted a region-based approach for safe concurrency that builds on Milano et al’s ideas: https://github.com/apple/swift-evolution/blob/main/proposals...

No, it's not. Refcounting CAN be a garbage collection algorithm, but in Swift it's deterministic and done at compile time. Not to mention recently added support for non-copyable types that enforces unique ownership: https://github.com/apple/swift-evolution/blob/main/proposals...

You can stackallocate buffers with unsafe Swift but it's not exactly fun to use. https://github.com/apple/swift-evolution/blob/main/proposals/0322-temporary-buffers.md

If the docs do not suffice, read the concurrency proposals of Swift Evolution. The authors describe the semantics in a very detailed way there.

Lua is easy to learn, dynamically typed and doesn't need to be compiled: it's perfect to get instant reload and it's perfect for small projects.

If you want to create games using Kotlin, you can try my 3D Game Engine: minigdx (https://github.com/minigdx/minigdx).

Or other game engine:

- https://littlekt.com/ (LittleKt (Little Kotlin) is a multiplatform 2D game framework written in Kotlin)

- https://korge.org/ (Korge - Modern Multiplatform Game Engine for Kotlin.)

- https://libgdx.com/ (LibGDX, it's for Java but you can use Kotlin, if you don't want to target the web platform)

- https://korge.org/ (Korge - Modern Multiplatform Game Engine for Kotlin.) - https://github.com/minigdx/minigdx (Minigdx - Minimalist Game Framework using Kotlin Multiplatform / I created it before creating Tiny) - https://libgdx.com/ (LibGDX, it's for Java but you can use Kotlin, if you don't want to target the web platform)

The new version of this Kotlin Multiplatform Game Engine https://korge.org/ (JS, JVM (Windows/Linux/Mac), Android, K/N(Windows, Linux, Mac, iOS)) along the korlibs (kds, kmem, klock, krypto, korma, korio, korim, korau, korgw, korge, korte) has been released.

there is actually a really nice library that might be what you're looking for: https://korge.org/
