Would Swift be a good scripting language for godot?

[theDapperRaven]

I've recently learned swift, and coming from loosely typed languages like python, it was quite a transition! But the more I learned, the more value I saw in it.
Its speed. Its safety. It's powerful typing systems.
Indeed, the language is quite good for games. I've made a few games using Apple's SceneKit and SpriteKit, and the language works very well.

I wonder...
Could Swift be a good scripting language for godot?

The protocols and structs could make Swift integrate quite well into the engine, I think.

How it could look:
(please note that I am not a swift expert and I may have made a few errors here)
(also note that this is just my best guess of how the API would work)

import Godot
import Foundation

enum CharacterClass { // I am unsure if definitions like this will be OK or if they'll need to be inside the main class. 
    case mage
    case warrior
    case archer

    var strength: Int {
        switch self {
            case mage: 30
            case warrior: 50
            case archer: 40
        }
    }
}

public final class PlayerController: CharacterBody2D, NodeAttachable { // not quite sure just how it will be implemented, but I can see protocols being used. 
    @export var mainSprite: Sprite2D?
    @exportSlider var movementSpeed: Int?
    @export var characterClass: CharacterClass = .warrior

    let maxHitpoints = 100

    var health: Int = 100 {
        didSet {
           if health < 1 { die() }
           if health > maxHitpoints {
                health = maxHitpoints
            }
        }
    }

    var currentStrength: Double {
        return (health / 100) * characterClass.strength
    }

    var onDeathCode: (() -> Void)?

    override func ready() {
        GDPrint("player spawned")
        var chosenSprite: String // hey, maybe we could use URLs for this.
        switch characterClass {
            case:
                chosenSprite = "res://sprites/character1"
            case:
                chosenSprite = "res://sprites/character2"
            case:
                chosenSprite = "res://sprites/character3"
        do {
            mainSprite!.texture = try Load(chosenSprite)
        } catch {
             mainSprite!.texture = try! Load("res://Icon.svg")
        }
    }

    func getInput() {
	var inputDirection = GDInput.getVector(.left, .right, .up, .down)
	velocity = inputDirection * movementSpeed
    }

    override func _physics_process(delta: Double) {
	getInput()
	moveAndSlide()
    }

    func die() {
        onDeathCode?()
        queueFree()
    }


    public func takeDamage(by amount: Int) {
        health -= amount
    }
}

Of course, there are probably thousands of technical issues I am not considering. Can swift compile for all of godot's platforms? Are we able to create a Swift API that is convenient to use? Is this actually a good idea?

Let's see some thoughts!
