Help with a practice Swift App!

Ok. I just finished make my first app through the Swift Track. It was great! (the randomly generating fact app).

So, I decided before moving on I would make another app that was similar to keep practicing and reinforce some of the newness of Xcode. So, I went for it and everything looks how I think it should be, but when I go to simulate the app it kicks back with an error. It shows some info in the debug, but I'm not far enough along to know what any of it means.

It's basically an app that randomly generates a student name (I'm a teacher) to call on them or what not. 3 buttons. 1 for anyone, and then a button for a random boy, or a random girl. Right now I've only done code for the main button. some screen shots are at the bottom, but here is the code:

StudentList.swift

import GameKit

class StudentName {
    var name: String
    var gender: String

    required init(name: String, gender: String) {
        self.name = name
        self.gender = gender
    }
}

struct StudentChoice {
    let homeroom = [
        StudentName(name: "Boy 1", gender: "Boy"),
        StudentName(name: "Boy 2", gender: "Boy"),
        StudentName(name: "Boy 3", gender: "Boy"),
        StudentName(name: "Girl 1", gender: "Girl"),
        StudentName(name: "Girl 2", gender: "Girl"),
        StudentName(name: "Girl 3", gender: "Girl")
    ]

    func getRandomStudent() -> StudentName {

        let randomNumber = GKRandomSource.sharedRandom().nextIntWithUpperBound(homeroom.count)

        return homeroom[randomNumber]
    }
}

ViewController

import UIKit

class ViewController: UIViewController {

    @IBOutlet weak var studentNameDisplay: UITextField!

    let studentChoice = StudentChoice()

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.

        studentNameDisplay.text = studentChoice.getRandomStudent().name
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    @IBAction func generateStudent() {
        studentNameDisplay.text = studentChoice.getRandomStudent().name
    }
}
