Swift UITableView subview appears but controller never called - ios

Question

I'm building a simple swift iOS app with a TableView that only takes up part of the screen. I have a FirstViewController that handles a long of info on the page and is the default landing page (it works as expected). A section of the page is a table view which I have created a new controller for BucketViewController.swift. That file looks like:
import UIKit
class BucketViewController: UITableViewController {
var buckets = [String]()
var newBucket: String = ""
override func viewDidLoad() {
print("INSIDE BUCKET")
super.viewDidLoad()
buckets = ["A", "B", "C"]
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return buckets.count
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
print("TABLEVIEW")
let cell = tableView.dequeueReusableCellWithIdentifier("bucketCell", forIndexPath: indexPath) as! UITableViewCell
cell.textLabel!.text = buckets[indexPath.row]
return cell
}
}
In the storyboard, there is a Table View with the class bucketViewController. There is a prototype cell called bucketCell with a textLabel.
When I run the app the tableView appears, but it is blank. INSIDE BUCKET is never printed which makes me think the controller is never called. Any idea why this is?
import UIKit
class FirstViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
