How to achieve that placeholder text disappears character by character in UITextField

Answer 1

For that situation use attributed string in swift like bellow,

let attributeFontSaySomething : [String : Any] = [NSFontAttributeName : UIFont.systemFont(ofSize: 12.0)]
let attributeColorSaySomething : [String : Any] = [NSForegroundColorAttributeName : UIColor.blue]

var attributes = attributeFontSaySomething
for (key, value) in attributeColorSaySomething {
    attributes(value, forKey: key)
}

let attStringSaySomething = NSAttributedString(string: "Say something", attributes: attributes)
