Pulling data from parse in swift as an array

I have a list of competitions in a class on parse named "Competitions", and I need to pull the list of competitions from said class to populate an array to populate a UI PickerView. What is the easiest way possible to complete this?

Thank you.

//edit with code

    override func viewDidLoad() {
    super.viewDidLoad()
    var compQuery = PFQuery(className:"Competitions")
    compQuery.whereKey("teamID", equalTo:"1")
    compQuery.findObjectsInBackgroundWithBlock {
        (competitions: [AnyObject]!, error: NSError!) -> Void in
        if error == nil {
            // Do something with the found objects
            for competition in competitions {
                NSLog("%@", competition["compName"] as String)
                self.competitionArray += [competition["compName"] as String]
            }
        } else {
            // Log details of the failure
            NSLog("Error: %@ %@", error, error.userInfo!)
        }
    }
}

// Edited with new errors Since I am adding the objects to a UIPicker for the user to select a value, I used this to get the objects as an array of strings,

var competitionArrayString:Array = [competitionArray as AnyObject as [String]]

however I am receiving the error that my class does not have the member "competitionArray"

import UIKit
import Swift
import Parse

class CompetitionViewController: UIViewController  {
var competitionArrayString:Array = [""]
var competitionArray:NSMutableArray = []

override func viewDidLoad() {
    super.viewDidLoad()
    var compQuery = PFQuery(className:"Competitions")
    compQuery.whereKey("teamID", equalTo:"1")

    self.competitionArray = NSMutableArray()

    compQuery.findObjectsInBackgroundWithBlock {
        (competitions: [AnyObject]!, error: NSError!) -> Void in
        if error == nil {
            // Do something with the found objects
            for competition in competitions {
                NSLog("%@", competition["compName"] as String)
                self.competitionArray.addObject([competition["compName"] as String])
            }
        } else {
            // Log details of the failure
            NSLog("Error: %@ %@", error, error.userInfo!)
        }
    }
}

var competitionArrayString:Array = [competitionArray as AnyObject as [String]]

func numberOfComponentsInPickerView(pickerView: UIPickerView) -> Int {
    return 1
}


func pickerView(pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
    return competitionArrayString.count
}


func pickerView(pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String! {
    return competitionArrayString[row]
}

func pickerView(pickerView: UIPickerView!, didSelectRow row: Int, inComponent component: Int)
{
    var selectedData = competitionArrayString[row]
    var userDefaults = NSUserDefaults.standardUserDefaults()
    userDefaults.setValue(selectedData, forKey: "competitionData");
    userDefaults.synchronize();

    println("You Selected: \(selectedData)")


}
