swift - use an integer for loop in a variable's name

Question

I' like to doe something like this :

for i in 0...3 {
let skspritenode\(i) = SKSpriteNode(imageNamed: "Layer_\(i)")
self.addChild(skspritenode\(i))
}

that doesn't work because my skspritenode(i) is a let and not a string and I have tried this:

for i in 0...3 {
let skspritenode = SKSpriteNode(imageNamed: "Layer_\(i)")
self.addchild(skspritenode)
}

which doesn't work because skspritenode already has a parent.

Is there a way of doing this in a for loop or do i have to declare each let separately? Thank you in advanced

Why would you need to name each node differently? skspritenode variable is scoped in for loop, thus the following code should work just fine:

for i in 0...3 {
  let skspritenode = SKSpriteNode(imageNamed: "Layer_\(i)")
  self.addchild(skspritenode)
}

Your point

which doesn't work because skspritenode already has a parent

is incorrect, since you're creating new SKSpriteNode on each iteration.
