How to increase image size dynamically in Swift, Xcode?

I'm trying to create an application where an image is increasing in size and want to change the rate in which it does/be able to touch for a function. I'm new to Swift, thank you for anyone who helps. This is within "Game" applications of Xcode -- Code:

class GameScene: SKScene {

let image = SKSpriteNode(imageNamed: "Circle-icon")
let num = 1
var grow = 0 
override func didMove(to view: SKView) (
    let bg = SKSpriteNode(imageNamed: "background")
    bg.size = self.size
    bg.position = CGPoint(x: self.size.width/2, y: self.size.height/2) bg.zPosition = 0
    self.addChild(bg)


    image.position = CGPoint(x: self.size.width/2, y: self.size.height * 0.2)
    image.zPosition = 1
    while grow < 10 {
        let growMore = grow
        image.setScale(CGFloat(growMore))
        grow += 0.1
          } 
    self.addChild(image)
   }
}

Run an SKAction on the sprite you wish to scale. This example scales it to size 300x300 over a period of five seconds, but obviously you'd want to adjust that to your liking. 

 let scale = SKAction.scale(to: CGSize(width: 300, height: 300), duration: 5.0)
 yourSprite.run(scale)

You can also scale by increments by using the separate scale method with different constructor scale(by: )
