I thought Twitter Kit was supposed to help developers integrate Twitter in a few lines of code. The online documentation is poor to say the least. I am simply trying to display a single user's timeline in my app within a table view controller. I want read only, guest only access to the timeline. The below copy/paste from the online documentation simply brings up 2 cells populated with a greyed out image and a twitter logo but no tweets. What is wrong? Thanks

```
import UIKit
import TwitterKit

class TwitterViewController: UITableViewController, TWTRTweetViewDelegate {

    let tweetTableReuseIdentifier = "TweetCell"
    // Hold all the loaded Tweets
    var tweets: [TWTRTweet] = [] {
        didSet {
            tableView.reloadData()
        }
    }
    let tweetIDs = ["20", // @jack's first Tweet
        "510908133917487104"] // our favorite bike Tweet

    override func viewDidLoad() {
        // Setup the table view
        tableView.estimatedRowHeight = 150
        tableView.rowHeight = UITableViewAutomaticDimension // Explicitly set on iOS 8 if using automatic row height calculation
        tableView.allowsSelection = false
        tableView.registerClass(TWTRTweetTableViewCell.self, forCellReuseIdentifier: tweetTableReuseIdentifier)

        Twitter.sharedInstance().logInGuestWithCompletion { guestSession, error in
            if (guestSession != nil) {
                // make API calls that do not require user auth
            } else {
                println("error: \(error.localizedDescription)");
            }
        }
        // Load Tweets
        Twitter.sharedInstance().APIClient.loadTweetsWithIDs(tweetIDs) { tweets, error in
            if let ts = tweets as? [TWTRTweet] {
                self.tweets = ts
            } else {
                println("Failed to load tweets: \(error.localizedDescription)")
            }
        }
    }

    // MARK: UITableViewDelegate Methods
    override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return self.tweets.count
    }

    override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        let tweet = tweets[indexPath.row]
        let cell = tableView.dequeueReusableCellWithIdentifier(tweetTableReuseIdentifier, forIndexPath: indexPath) as TWTRTweetTableViewCell
        cell.tweetView.delegate = self
        return cell
    }

    override func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
        let tweet = tweets[indexPath.row]
        return TWTRTweetTableViewCell.heightForTweet(tweet, width: CGRectGetWidth(self.view.bounds))
    }
}
