CKAsset won't show in tableview image

I have an optional image in the cloudkit DB(checked DB and the image is there in cases where I added it in my testing). I have created a class that initializes the record fields into variables I use in my tableview. I have a custom cell as well. But the image won't display in my custom tableview cell. I don't know if having an optional image in a tableview image is causing a problem or if there's an issue with my code/settings in cloudkit.

Any help is greatly appreciated, as I've been stuck for over a week and there's little to nothing online about this.

Here's my class code:

var feedResults = [UserPosts]()

class UserPosts {

var record: CKRecord
var description: String
var username: String
//var image: CKAsset? // tried also initializing the CKAsset separately
var postPic: UIImage?


init(record: CKRecord) {

    self.record = record
    self.description = record.objectForKey("description") as String
    self.username = record.objectForKey("username") as String
   // self.image = record.objectForKey("postPic") as? CKAsset


    if var pic = record.objectForKey("postPic") as CKAsset! {

           self.postPic = UIImage(contentsOfFile: pic.fileURL.path!)

            // below is the other way I've seen it done.
               // var url = pic.fileURL!
               // var imageData = NSData(contentsOfFile: url.path!)
              // self.postPic = UIImage(data: imageData!)

    }
}

}

Here's my tableview code:

    override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as TableViewCell

    let record = feedResults[indexPath.row]
    cell.postDescription.text = record.description
    cell.userName.text = record.username

    if record.postPic != nil {

         cell.postPic.image = record.postPic!

    }

    return cell
}

Also I've seen a couple ways of pulling a CKAsset into a UIImage. The first way, is how I saw Apple do it in their CloudKitAtlas project. Although I'm not well versed in Obj-C, I think I followed it correctly - CloudKitAtlas Example

I've also seen it done using NSData(contentOFFile:) and UIImage(data:), as shown in this post here: SO CKAsset Example

You can display the image from the CKAsset like this:

    var img = record.valueForKey("Picture") as? CKAsset
    cell.imageView?.image = UIImage(contentsOfFile: img!.fileURL.path!)

Hope this helps!

Try doing it without the .paths and using contentsOfURL. This is how I do this (within your if for the CKAsset):

         if var data = NSData(contentsOfURL: pic!.fileURL) {
            self.postPic =  UIImage(data: data!)!
        }

And besides that... You do a dequeueReusableCellWithIdentifier but don't check if it returns nil. You should create a new cell instance If it was nil
