Answer 1

Customized way to add padding in "left", "right" or "both" side od UITextField.

Step 1:- Add this UITextfield extension

extension UITextField {

    enum PaddingSide {
        case left(CGFloat)
        case right(CGFloat)
        case both(CGFloat)
    }

    func addPadding(_ padding: PaddingSide) {

        self.leftViewMode = .always
        self.layer.masksToBounds = true


        switch padding {

        case .left(let spacing):
            let paddingView = UIView(frame: CGRect(x: 0, y: 0, width: spacing, height: self.frame.height))
            self.leftView = paddingView
            self.rightViewMode = .always

        case .right(let spacing):
            let paddingView = UIView(frame: CGRect(x: 0, y: 0, width: spacing, height: self.frame.height))
            self.rightView = paddingView
            self.rightViewMode = .always

        case .both(let spacing):
            let paddingView = UIView(frame: CGRect(x: 0, y: 0, width: spacing, height: self.frame.height))
            // left
            self.leftView = paddingView
            self.leftViewMode = .always
            // right
            self.rightView = paddingView
            self.rightViewMode = .always
        }
    }        
}
