I have the following subclass of UITableViewCell
import UIKit
public class AlbumTableViewCell : UITableViewCell {
@IBOutlet weak var albumNameLabel: UILabel!
@IBOutlet weak var albumThumbnailImage: UIImageView!
}
I then have the identifier on a prototype cell set to AlbumTableViewCellIdentifier.
Finally, in my view controller, I have assigned a string value that I use in the controller to represent the identifier.
class HomeViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
let AlbumTableViewCellIdentifier = "AlbumTableViewCellIdentifier";
}
Within the same view controller, I have the following cellforRowAtIndexPath method.
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
var cell:AlbumTableViewCell;
cell = tableView.dequeueReusableCellWithIdentifier(AlbumTableViewCellIdentifier, forIndexPath: indexPath) as! AlbumTableViewCell;
let currentTag = cell.tag + 1;
cell.tag = currentTag;
let album:PHAssetCollection = self.albums[indexPath.row] as! PHAssetCollection;
cell.albumNameLabel.text = album.localizedTitle;
// No assets were returned for this collection, so we can't assign an album thumbnail.
let assetFetchResult:PHFetchResult = PHAsset.fetchAssetsInAssetCollection(album, options: nil);
if (assetFetchResult.count == 0) {
return cell;
}
let asset = assetFetchResult.objectAtIndex(0);
self.imageManager.requestImageForAsset(
asset as! PHAsset,
targetSize: AssetGridThumbnailSize,
contentMode: PHImageContentMode.AspectFill,
options: nil) { (image, info) -> Void in
if (cell.tag == currentTag) {
cell.albumThumbnailImage.image = image;
}
}
return cell;
}
The second line of the cellForRowAtIndexPath method throws an exception.
cell = tableView.dequeueReusableCellWithIdentifier(AlbumTableViewCellIdentifier, forIndexPath: indexPath) as! AlbumTableViewCell;
It sounds like an issue finding my custom cell class, but i'm not sure what's going on.

What am I doing wrong that is causing it to not properly dequeue a UITableViewCell for me?
Edit
I have also made sure that my Custom Class has been assigned to my subclass of UITableViewCell
