Isn't this a for loop?

Isn't the playlist suppose to be the Playlist[1] since it is a let (Constant), or *Playlist[lastIndex] since it is a for loop?

    playlistsArray += [playlistImageView0, playlistImageView1, playlistImageView2, playlistImageView3, playlistImageView4, playlistImageView5]


   for index in 0..<playlistsArray.count {
        let playlist = Playlist(index: index)
        let playlistImageView = playlistsArray[index]

        playlistImageView.image = playlist.icon
        playlistImageView.backgroundColor = playlist.backgroundColor
    }

Yes, the 0 ..< playlistsArray.count is basically a range that you're looping through.

For example:

let playlistArray = ["0", "1", "2", "3", "4", 5"]
for index in 0...5 {
   print(playlistArray[index])
}

so an output of the program would be:

0
1
2
3
4
5
