How do you set an Attributed Title Color for State in Swift

Swift 4 & 5

    // create the button
    let button = UIButton(frame: CGRect(x: 0, y: 0, width: 100, height: 50))
    button.backgroundColor = UIColor.yellow
    
    // set the attributed title for different states
    
    // .Selected
    let mySelectedAttributedTitle = NSAttributedString(string: "Click Here",
                                                       attributes: [NSAttributedStringKey.foregroundColor : UIColor.green])
    button.setAttributedTitle(mySelectedAttributedTitle, for: .selected)
    
    // .Normal
    let myNormalAttributedTitle = NSAttributedString(string: "Click Here",
                                                     attributes: [NSAttributedStringKey.foregroundColor : UIColor.blue])
    
    
    button.setAttributedTitle(myNormalAttributedTitle, for: .normal)

Swift 3

// create the button
let button = UIButton(frame: CGRect(x: 0, y: 0, width: 100, height: 50))
button.backgroundColor = UIColor.yellow

// set the attributed title for different states

// .Selected
let mySelectedAttributedTitle = NSAttributedString(string: "Click Here",
                                               attributes: [NSForegroundColorAttributeName : UIColor.green])
button.setAttributedTitle(mySelectedAttributedTitle, for: .selected)

// .Normal
let myNormalAttributedTitle = NSAttributedString(string: "Click Here",
                                             attributes: [NSForegroundColorAttributeName : UIColor.blue])


button.setAttributedTitle(myNormalAttributedTitle, for: .normal)

// create the button
let button = UIButton(frame: CGRect(x: 0, y: 0, width: 100, height: 50))
button.backgroundColor = UIColor.yellowColor()

// set the attributed title for different states

// .Selected
let mySelectedAttributedTitle = NSAttributedString(string: "Click Here",
    attributes: [NSForegroundColorAttributeName : UIColor.greenColor()])
button.setAttributedTitle(mySelectedAttributedTitle, forState: .Selected)

// .Normal
let myNormalAttributedTitle = NSAttributedString(string: "Click Here",
    attributes: [NSForegroundColorAttributeName : UIColor.blueColor()])
button.setAttributedTitle(myNormalAttributedTitle, forState: .Normal)
