Gamescene spriteNodes in array - swift

Question

Getting an error on this pice of code.
I Don't want to go through the spriteNode on GameScene.sks manually (in code) - the for loop must work somehow? Any ideas...
let sprites:[SKSpriteNode] = [block1, block2, block3, block4,
block5, block6, block7, block8, block9, block10, block11,
block12, block13, block14, block15, block16, block17,
block18, block19, block20, block21, block22, block23,
block24, block25, block26, block27, block28, block29,
block30, block31, block32, block33, block34, block35,
block36, block37, block38, block39, block40, block41,
block42, block43, block44, block45, block46, block47,
block48, block49, block50, block51, block52, block53,
block54, block55, block56, block57, block58, block59,
block60, block61, block62, block63, block64, block65,
block66, block67, block68, block69, block70, block71,
block72, block73, block74, block75, block76, block77,
block78, block79, block80, block81, block82, block83, block84]
for sprite in sprites {
self.sprite; in sprites = (self.childNode(withName: sprite.name) as? SKSpriteNode)!
sprite.name = "Green"
sprite.zPosition = 3
}

I'm guessing that from your not very descriptive description that you have a bunch of SKSpriteNodes in your .sks file and you want to loop through them in code to setup them up???
something like this might work better for you, if that is indeed what you are looking for.
let spriteNames: [String] = ["block1", "block2", "block3"]
let sprites = [SKSpriteNode]()
for spriteName in spriteNames {
if let sprite = self.childNode(withName: spriteName) as? SKSpriteNode {
sprite.name = "Green"
sprite.zPosition = 3
sprites.append(sprite)
}
}
