1,962 PointsNeed Help - Tap is not registering, No ERRORS
I think the problem has something to do with the connections. I have reconnection the Outlets and Actions, Even Clean the App as well. As the App is running the connection symbols on the side where the line numbers are become hollow. Tap is not registering any more. No Errors Found. Please Help
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
}
}

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {

for index in 0..<playlistsArray.count {
to this:
for index in 0..<playlistsArray.count> {
