Answer 1

use the rightView property of the UITextField. Basically, there are two properties (this one and leftView accordingly) that allow you to place custom views/controls inside the UITextField. You can control whether those views are shown or not by means of rightViewMode/leftViewMode properties:

textField.rightView = btnColor
textField.rightViewMode = .unlessEditing

for e.g

let button = UIButton(type: .custom)
button.setImage(UIImage(named: "send.png"), for: .normal)
button.imageEdgeInsets = UIEdgeInsetsMake(0, -16, 0, 0)
button.frame = CGRect(x: CGFloat(txt.frame.size.width - 25), y: CGFloat(5), width: CGFloat(25), height: CGFloat(25))
button.addTarget(self, action: #selector(self.refresh), for: .touchUpInside)
textField.rightView = button
textField.rightViewMode = .always

and call the action as

@IBAction func refresh(_ sender: Any) {
}
