Sahil has a great answer and I wanted to take that and expand it into an @IBDesignable so developers can add images to their UITextFields on the Storyboard.

Swift 4.2

import UIKit

@IBDesignable
class DesignableUITextField: UITextField {
    
    // Provides left padding for images
    override func leftViewRect(forBounds bounds: CGRect) -> CGRect {
        var textRect = super.leftViewRect(forBounds: bounds)
        textRect.origin.x += leftPadding
        return textRect
    }
    
    @IBInspectable var leftImage: UIImage? {
        didSet {
            updateView()
        }
    }
    
    @IBInspectable var leftPadding: CGFloat = 0
    
    @IBInspectable var color: UIColor = UIColor.lightGray {
        didSet {
            updateView()
        }
    }
    
    func updateView() {
        if let image = leftImage {
            leftViewMode = UITextField.ViewMode.always
            let imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 20, height: 20))
            imageView.contentMode = .scaleAspectFit
            imageView.image = image
            // Note: In order for your image to use the tint color, you have to select the image in the Assets.xcassets and change the "Render As" property to "Template Image".
            imageView.tintColor = color
            leftView = imageView
        } else {
            leftViewMode = UITextField.ViewMode.never
            leftView = nil
        }
        
        // Placeholder text color
        attributedPlaceholder = NSAttributedString(string: placeholder != nil ?  placeholder! : "", attributes:[NSAttributedString.Key.foregroundColor: color])
    }
}

What is happening here?

This designable allows you to:

Set an image on the left
Add padding between the left edge of the UITextField and the image
Set a color so the image and the Placeholder text matches

Notes

For image color to change you have to follow that note in the comment in the code
The image color will not change in the Storyboard. You have to run the project to see the color in the Simulator/device.

To create padding  I like to place the image inside of a container view  You can remove the background color once you are happy with the icon placement      let imageView   UIImageView frame  CGRect x  8 0  y  8 0  width  24 0  height  24 0   let image   UIImage named   my icon   imageView image   image imageView contentMode    scaleAspectFit imageView backgroundColor   UIColor red  let view   UIView frame  CGRect x  0  y  0  width  32  height  40   view addSubview imageView  view backgroundColor    green textField leftViewMode   UITextFieldViewMode always textField leftView   view

I Just want to add some more thing here   If you want to add the image on UITextField on left side  use leftView property of UITextField   NOTE  Don t forget to set leftViewMode to UITextFieldViewMode Always and for right rightViewMode to UITextFieldViewMode Always anddefault is UITextFieldViewModeNever   for e g  For adding an image on left side  textField leftViewMode   UITextFieldViewMode Always let imageView   UIImageView frame  CGRect x  0  y  0  width  20  height  20   let image   UIImage named  imageName  imageView image   image textField leftView   imageView   For adding an image on right side  textField rightViewMode   UITextFieldViewMode Always let imageView   UIImageView frame  CGRect x  0  y  0  width  20  height  20   let image   UIImage named  imageName  imageView image   image textField rightView   imageView   NOTE  some things you need to take care while adding an image on UITextField either on the left side or right side    Don t forget to give a frame of ImageView which are you going to add on UITextField  let imageView   UIImageView frame  CGRect x  0  y  0  width  20  height  20   if your image background is white then image won t visible on UITextField if you want to add an image to the specific position you need to add ImageView as the subview of UITextField    Update For Swift 3 0   Mark Moeykens Beautifully expended it and make it  IBDesignable   I modified and added some more features  add Bottom Line and padding for right image  in this   NOTE if you want to add an image on the right side you can select the Force Right-to-Left option in semantic in interface builder But for right image padding won t work until you will override rightViewRect method       I have modified this and can download the source from here ImageTextField

I don t think that frame-based solutions are a good approach  because it won t be available on an iPad in some cases  The ideal solution would be to add constraints from imageView to textfield right view  but it s not that easy  The right view does not appear to be in textfield view hierarchy unless it is required  so you need to do the following      private let countryTextField  UITextField             let countryTextField   UITextField           countryTextField translatesAutoresizingMaskIntoConstraints   false         countryTextField rightViewMode    always                  let button   UIButton type   system          button setImage UIImage named   quot yourImageName quot    for   normal          button translatesAutoresizingMaskIntoConstraints   false                  countryTextField rightView   button         countryTextField setNeedsLayout     Add rightView in textField hierarchy         countryTextField layoutIfNeeded     Add rightView in textField hierarchy                  button topAnchor constraint equalTo  countryTextField topAnchor  isActive   true         button bottomAnchor constraint equalTo  countryTextField bottomAnchor  isActive   true         button widthAnchor constraint equalTo  countryTextField heightAnchor  isActive   true                  return countryTextField          And the result on any device is   Also  my solution works with textfield left view

Why don t you go for the easiest approach  For most cases you want to add icons like font awesome    Just use font awesome library and it would be as easy to add an icon to an text field as this   myTextField setLeftViewFAIcon icon   FAPlus  leftViewMode   always  textColor   red  backgroundColor   clear  size  nil    You would need to install first this swift library  https   github com Vaberer Font-Awesome-Swift
