Hi, I'm a little stuck on this part where “The last step for our grid is to call createItem() once for each item in our grid. ”

   for x in 0 ..< itemsPerRow {
        var col = [Item]()
    }
    for y in 0 ..< itemsPerColumn
    {
        let item = createItem(row: y, col: x)
        col.append(col)
    }

“ put this code at the end of didMove(to:):” I did this in GameScene.swift

After I did this step, I find that the x and the col are not declared. Am I missing a step to declare those or am I putting this in the wrong spot?

Hi, you need to nest the second loop inside the first one like so:

 for x in 0 ..< itemsPerRow {
      var col = [Item]()

      for y in 0 ..< itemsPerColumn
      {
          let item = createItem(row: y, col: x)
          col.append(col)
      }
 }

Hey @nemecek-filip thanks for that but the x is still undeclared? Is it implicitly declared with the For?

Using this now i have a "Missing argument label 'contentsOf:' in call" error instead which I'm confused about.
