How to get a Canvas in a Swift Playground

I would like to get a canvas that I can use to draw on. The target would be an iOS based Swift playground. I searched the documentation and I could not found an object named Canvas, but if there is something similar to it then it would be good for me as well.

Answer

You can use something similar to this, note you don't have to use Sprite Kit classes.

import UIKit 
import PlaygroundSupport 
import SpriteKit 


//    Playground Container Setup 
// 
// 
let containerWidth: CGFloat = 667.0 
let containerHeight: CGFloat = 375.0 
let containerCenter: CGPoint = CGPoint(x: (containerWidth/2), y: (containerHeight/2)) 


let containerView = SKView(frame: CGRect(x: 0.0, y: 0.0, width: containerWidth, height: containerHeight)) 


PlaygroundPage.current.liveView = containerView 


let containterScene: SKScene = SKScene(size: CGSize(width: containerWidth, height: containerHeight)) 
containerView.presentScene(containterScene)

I've created a wrapper class to make this easier for everyone. Download the Playground here on github
