Swift - Change color and size of text when UIButton is tapped

Basically, I have a three buttons on my main screen.

When I select one of these buttons, I would like the text on the selected button to change to bold and change color (blue).

When I select a different button, I would like the newly selected button to change to bold and change color(blue), and the previously selected button to go back to normal. (non-bold and black text)

I have these buttons sending an action to the script.

This is what I have, I can't seem to get it to work. Help would be much appreciated!

@IBAction func buttonOne(sender: UIButton){
    sender.setTitleColor(UIColor.blueColor(), forState: UIControlState.Highlighted)
}

I have tried .Highlighted and .Selected on the UIControlState, neither seem to work. I have also tried the following, but I cant get it to work. 

@IBAction func buttonOne(sender: UIButton){
    sender.titleLabel?.textColor = UIColor.blueColor()
}

I figured that since the sender was a UIButton, and it was the button that was clicked, taking the values off of it and resetting them would work. I do believe I am missing something.

Thank you

Provide tags to all buttons, connect each button actions to same function and try the following code:

@IBAction func butnClicked (sender : UIButton) {

    for tg in 1...2 {
        print(sender.tag)
        let tmpButton = self.view.viewWithTag(tg) as? UIButton
        if tmpButton?.tag == sender.tag {
          tmpButton?.setTitleColor(.red, for: .normal)
        } else {
           tmpButton?.setTitleColor(.gray, for: .normal)
        }
    }

Hope will be helping.

Maybe you can do with a transform...

@IBAction func buttonPressed(sender: UIButton) {
    sender.titleLabel!.textColor = UIColor.blueColor()
    sender.transform = CGAffineTransformMakeScale(0.8, 0.8)
}

@IBAction func buttonReleased(sender: UIButton) {
    sender.titleLabel!.textColor = UIColor.redColor()
    sender.transform = CGAffineTransformIdentity
}

Sounds like you want UIControlState.Normal

Selected does nothing in most cases, and Highlighted is only while you're pressing the button. See more info here: https://developer.apple.com/library/ios/documentation/uikit/reference/uicontrol_class/index.html#//apple_ref/doc/constant_group/Control_State
