I'm new to iOS. What would be the right toolkit to create something like a swarm animation with thousands of objects on the screen moving at high speed?

Would it be possible to work with thousands of physical bodies in SpriteKit?

import SwiftUI
import SpriteKit
class GameScene: SKScene {
override func didMove(to view: SKView) {
physicsBody = SKPhysicsBody(edgeLoopFrom: frame)
}
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
//with this we would only process single touch
// good question how to process multi touch
guard let touch = touches.first else { return }
let location = touch.location(in: self)
let box = SKSpriteNode(color: SKColor.red, size: CGSize(width: 50, height: 50))
box.position = location
box.physicsBody = SKPhysicsBody(rectangleOf: CGSize(width: 50, height: 50))
addChild(box)
}
}
struct ContentView: View {
var scene: SKScene {
let scene = GameScene()
scene.size = CGSize(width: 300, height: 400)
scene.scaleMode = .fill
return scene
}
func initScene () {
// why doesn't it work
scene.removeAllActions()
scene.removeAllChildren()
}
var body: some View {
VStack {
Text("Hello, world!")
.padding()
Button("Reset") {
initScene()
}
SpriteView(scene: scene)
.frame(width: 300, height: 400)
.ignoresSafeArea()
}
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView( )
}
}
I noticed that .navigationTitle() behaves differently in iOS and macOS. But couldn't find a reference to this anywhere. On iOS I have to put it on the NavigationViews content but on macOS I have to put it directly on NavigationView for it to show up. I suppose I can make the code platform dependent but it is rather ugly. Am I doing something wrong? Has anyone else come across this?
