I have the same code as the video, but am getting tons of errors on a single line

For "let playlistImageView = playlistsArray[index]" I get these errors

  • type of expression is ambiguous without more context
  • type annotation missing in pattern
  • definition conflicts with previous value
  • consecutive statements on a line must be separated by ";"

import UIKit

class PlaylistMasterViewController: UIViewController {

var playlistsArray: [UIImageView] = []
@IBOutlet weak var playlistImageView0: UIImageView!

override func viewDidLoad() {
    super.viewDidLoad()

    playlistsArray.append(playlistImageView0)

    for index in 0..<playlistsArray.count {

        let playlist = Playlist(index: index)
        let playlistImageView = playlistsArray[index]
        playlistImageView.image = playlist.icon
        playlistImageView.backgroundColor = playlist.backgroundColor
    }
}

Hey Mateo,

Can you show me the code for your prepareForSegue method?

Hey Steven, I'm not really sure what I did (simply made the block look "cleaner" without touching the code) but it worked...

I guess I'll delete the question, but thanks for taking a look!
