Set left view of uitextfield make placeholder overlap on icon

[cchamnab]

I've tried following code to set left view of uitextfield but got placeholder overlap over icon when editing uitextfield.
txtUsername.leftViewMode = UITextField.ViewMode.always let imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 20, height: 20)) let image = UIImage(named: "icon_camera") imageView.image = image imageView.contentMode = .scaleAspectFit txtUsername.leftView = imageView
