Unrecognized selector for instance error Swift - swift

Question

Im creating a simple typing app with timer. The timer should be in a form of a progress bar that decrements every second.
To implement the progressbar, I intended to set the progress to 0.1 lesser to the current progress every 1 second. But there is an "Unrecognized selector for instance " error when i set the progress.
Is there any other way to work around.
import Foundation
import UIKit
class TestView: UIViewController, UITextInputTraits {
#IBOutlet weak var TestLabel: UILabel!
#IBOutlet weak var TypingField: UITextField!
#IBOutlet weak var progressView: UIProgressView!
var time : Float = 0.0
var timer: NSTimer!
var test = 0;
var progress : Float = 1
var myMutableString = NSMutableAttributedString()
var testStringArray = ["abode" , "tutorial" , "completed",
"war", "method", "continue",
"machine", "texting" , "iterate"]
var idx = 0;
var setProg : Float = 1
func textFieldDidChange(textField: UITextField) {
let s = TypingField.text!
if(s.characters.last == " "){
let word = s.stringByTrimmingCharactersInSet(NSCharacterSet.whitespaceCharacterSet())
if(!word.isEmpty){
print(testStringArray[idx])
if(word == testStringArray[idx]){
idx++;
TypingField.text = "";
TestLabel.text = testStringArray[idx];
}else{
TypingField.text = "";
}
}
}
}
func setProgress() {
setProg -= 0.1
progressView.progress = setProg <-- cannot decrement progress bar
}
override func viewDidLoad() {
super.viewDidLoad()
TypingField.autocorrectionType = .No
TypingField.autocapitalizationType = .None
timer = NSTimer.scheduledTimerWithTimeInterval(1, target: self, selector:Selector("setProgress"), userInfo: nil, repeats: true)
TestLabel.text = testStringArray[idx];
TypingField.addTarget(self, action: "textFieldDidChange:", forControlEvents: UIControlEvents.EditingChanged)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}

Answer 1

You have coded scheduledTimerWithTimeInterval in a manner like it is done with Objective-C. In Swift it is done differently. Instead of:
selector:Selector("setProgress")
just use:
selector:"setProgress"

Answer 2

Change the function declaration for func setProgress() to:
func setProgress(sender: NSTimer)
And change Selector("setProgress") to "setProgress:"
EDIT:
Apparently the method setProgress already exists, so you'll need to rename the function, e.g. to setProgressBar or something to that effect.
Method 'setProgress' with Objective-C selector 'setProgress:' conflicts with setter for 'progress' with the same Objective-C selector

Answer 3

I think the error was fix when I delete and recreate the progressbar.. it may have been as MikeG suggested about incorrect connection on the outlet. Anyways thanks all for your help..
