How do I prepare for segue to load different arrays in my TableViewController?

After days of struggling I can't figure out how to fix this. I am making a simple restaurant app. The foodMenuController contains 2 buttons which have to load different menu arrays into a tableViewController (lunch,breakfast). To define what menu should be loaded I was told by someone to use a variable -> contentMode.

In my TableViewController i set the contentMode to "0". In my foodMenuController i used prepare for segue with a identifier to set the contentMode to 1 (breakfast) and 2 (lunch).

Now the problem is that my table does not know when it is in contentMode 1 or 2 nor do I know where and how to write the code to indicate the table to load different arrays when in a certain contentMode. I hope someone can help me with the code i published below.

import UIKit

class foodMenuController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
            let foodMenuController = segue.destinationViewController as! foodTableViewController

            if segue.identifier == "showBreakfast" {
                foodMenuController.contentMode = 1
            } else if segue.identifier == "showBakery" {
                foodMenuController.contentMode = 2
            }
        }
    }

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

import UIKit

class foodTableViewCell: UITableViewCell {

    @IBOutlet weak var foodItem: UILabel!
    @IBOutlet weak var foodDescription: UILabel!
    @IBOutlet weak var foodPrice: UILabel!

    override func awakeFromNib() {
        super.awakeFromNib()
        // Initialization code
    }

    override func setSelected(selected: Bool, animated: Bool) {
        super.setSelected(selected, animated: animated)

        // Configure the view for the selected state
    }
}

import UIKit

class foodTableViewController: UITableViewController {

    // Content Mode Selection in menu
    var contentMode = 0

    // THIS SHOULD BE LOADED WHEN CONTENT MODE is "1" --> BREAKFAST
    var foodItems = ["Bread", "Coffee", "Nada"]
    var foodInfo = ["Good", "Nice", "Nothing"]
    var foodPrice = ["$1", "$100", "$12,40"]

    // THIS SHOULD BE LOADED WHEN CONTENT MODE IS "2" --> LUNCH
    var foodItems = ["Not bread", "Not Coffee", "Something"]
    var foodInfo = ["Not good", "Not nice", "Yes"]
    var foodPrice = ["$1", "$100", "$12,40"]


    override func viewDidLoad() {
        super.viewDidLoad()
    }

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

    // Table view data source
    override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
        return 1
    }

    override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return foodItems.count
    }

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

        cell.foodItem.text = foodItems[indexPath.row]
        cell.foodDescription.text = foodInfo[indexPath.row]
        cell.foodPrice.text = foodPrice[indexPath.row]

        return cell
    }
}

Change the array names as shown below.

// THIS SHOULD BE LOADED WHEN CONTENT MODE is "1" --> BREAKFAST
let breakfastItems = ["Bread", "Coffee", "Nada"]
let breakfastInfo = ["Good", "Nice", "Nothing"]
let breakfastPrice = ["$1", "$100", "$12,40"]

// THIS SHOULD BE LOADED WHEN CONTENT MODE IS "2" --> LUNCH
let lunchItems = ["Not bread", "Not Coffee", "Something"]
let lunchInfo = ["Not good", "Not nice", "Yes"]
let lunchPrice = ["$1", "$100", "$12,40"]

var foodItems: [String] = []
var foodInfo: [String] = []
var foodPrice: [String] = []

Now check the value of contentMode in ViewWillAppear

override func viewDidLoad() {
    super.viewDidLoad()

}

override func viewWillAppear(animated: Bool) {
    super.viewWillAppear(true)
    switch (contentMode){
    case 1:
        foodItems = breakfastItem
        foodInfo = breakfastInfo
        foodPrice = breakfastPrice
    case 2:
        foodItems = lunchItem
        foodInfo = lunchInfo
        foodPrice = lunchPrice
    default:
        break
    }
    tableView.reloadData()
}

This will copy the desired item, info ,price arrays into the foodItem, foodInfo and foodPrice arrays. The rest of your code will work fine and the UITableView will be populated as desired.
