Checkbox You can create your own CheckBox control extending UIButton with Swift  import UIKit  class CheckBox  UIButton          Images     let checkedImage   UIImage named   quot ic check box quot    as UIImage     let uncheckedImage   UIImage named   quot ic check box outline blank quot    as UIImage             Bool property     var isChecked  Bool   false           didSet               if isChecked    true                   self setImage checkedImage  for  UIControl State normal                else                   self setImage uncheckedImage  for  UIControl State normal                                             override func awakeFromNib             self addTarget self  action  selector buttonClicked sender     for  UIControl Event touchUpInside          self isChecked   false                     objc func buttonClicked sender  UIButton            if sender    self               isChecked    isChecked                    And then add it to your views with Interface Builder   Radio Buttons Radio Buttons can be solved in a similar way  For example  the classic gender selection Woman - Man   import UIKit  class RadioButton  UIButton       var alternateButton Array lt RadioButton gt            override func awakeFromNib             self layer cornerRadius   5         self layer borderWidth   2 0         self layer masksToBounds   true                func unselectAlternateButtons             if alternateButton    nil               self isSelected   true                          for aButton RadioButton in alternateButton                    aButton isSelected   false                         else               toggleButton                            override func touchesBegan   touches  Set lt UITouch gt   with event  UIEvent             unselectAlternateButtons           super touchesBegan touches  with  event                 func toggleButton             self isSelected    isSelected                override var isSelected  Bool           didSet               if isSelected                   self layer borderColor   Color turquoise cgColor               else                   self layer borderColor   Color grey 99 cgColor                                  You can init your radio buttons like this      override func awakeFromNib             self view layoutIfNeeded                    womanRadioButton selected   true         manRadioButton selected   false                override func viewDidLoad             womanRadioButton  alternateButton    manRadioButton           manRadioButton  alternateButton    womanRadioButton          Hope it helps

For checkboxes there is actually a built-in solution in the form of UITableViewCell accessories  You can set up your form as a UITableView in which each cell as a selectable option and use accessoryType to set a check mark for selected items   Here is a pseudo-code example       let items    SelectableItem       func tableView   tableView  UITableView  cellForRowAt indexPath  IndexPath  - gt  UITableViewCell                Get the item for the current row         let item   self items indexPath row                 dequeue and set up the  cell  as you wish                Use accessoryType property to mark the row as checked or not            cell accessoryType   item selected    checkmark    none            func tableView   tableView  UITableView  didSelectRowAt indexPath  IndexPath                Unselect row         tableView deselectRow at  indexPath  animated  false              Toggle selection         let item   self items indexPath row          item selected    item selected         tableView reloadData           Radio buttons however do require a custom implementation  see the other answers

The decision of checking or unchecking the checkbox button is something out of the scope of the view  View itself should only take care of drawing the elements  not deciding about the internal state of that  My suggested implementation is as follows   import UIKit  class Checkbox  UIButton        let checkedImage   UIImage named   checked       let uncheckedImage   UIImage named   uncheked       var action    Bool  - gt  Void     nil      private set  var isChecked  Bool   false           didSet              self setImage                  self isChecked   self checkedImage   self uncheckedImage                  for   normal                                    override func awakeFromNib             self addTarget              self              action  selector buttonClicked sender                 for   touchUpInside                   self isChecked   false             objc func buttonClicked sender  UIButton            if sender    self               self action   self isChecked                       func update checked  Bool            self isChecked   checked           It can be used with Interface Builder or programmatically  The usage of the view could be as the following example   let checkbox field   Checkbox frame  CGRect x  0  y  0  width  100  height  100   checkbox field action      weak checkbox field  checked in        any further checks and business logic could be done here     checkbox field  update checked  checked

For Radio Buttons and CheckBoxes there is nothing that comes built in    You can implement Checkboxes easily yourself  You can set an uncheckedImage for your button for UIControlStateNormal and a checkedImage for your UIControlStateSelected  Now on tap  the button will change its image and alternate between checked and unchecked image   To use radio buttons  you have to keep an Array for all the buttons that you want to behave as radio buttons  Whenever a button is pressed  you need to uncheck all other buttons in the array   For radio buttons you can use SSRadioButtonsController You can create a controller object and add buttons array to it like   var radioButtonController   SSRadioButtonsController   radioButtonController setButtonsArray  button1  button2  button3      The main principle is something like this here

Though some of the answers mention it rightly that we can use the Selected State to set an image for Selected state of the button  it won t work elegantly when the button has to have both image and text   Like many  I ended by subclassing UIButton  however  added support for setting images from Interface Builder    Below is my code   import UIKit  class CustomCheckbox  UIButton         IBInspectable var defaultStateImage  UIImage    nil           didSet              self setNeedsDisplay                         IBInspectable var selectedStateImage  UIImage    nil           didSet              self setNeedsDisplay                         IBInspectable var gapPadding  CGFloat   0           didSet              self setNeedsDisplay                         IBInspectable var isChecked  Bool   false           didSet              self setNeedsDisplay                        var defaultImageView  UIImageView    nil     var selectedImageView  UIImageView    nil      override init frame  CGRect            super init frame  frame          setup             required public init  coder aDecoder  NSCoder            super init coder  aDecoder          setup              override func layoutSubviews             super layoutSubviews           setup              func setup             if defaultStateImage    nil                defaultImageView   UIImageView image  defaultStateImage              defaultImageView  translatesAutoresizingMaskIntoConstraints   false              addSubview defaultImageView                let length   CGFloat 16              titleEdgeInsets left    length              NSLayoutConstraint activate                   defaultImageView  leadingAnchor constraint equalTo  self leadingAnchor  constant  -gapPadding                   defaultImageView  centerYAnchor constraint equalTo  self titleLabel  centerYAnchor  constant  0                   defaultImageView  widthAnchor constraint equalToConstant  length                   defaultImageView  heightAnchor constraint equalToConstant  length                                    if selectedStateImage    nil                selectedImageView   UIImageView image  selectedStateImage              selectedImageView  translatesAutoresizingMaskIntoConstraints   false              addSubview selectedImageView                let length   CGFloat 16              titleEdgeInsets left    length              NSLayoutConstraint activate                   selectedImageView  leadingAnchor constraint equalTo  self leadingAnchor  constant  -gapPadding                   selectedImageView  centerYAnchor constraint equalTo  self titleLabel  centerYAnchor  constant  0                   selectedImageView  widthAnchor constraint equalToConstant  length                   selectedImageView  heightAnchor constraint equalToConstant  length                                    if defaultImageView    nil               defaultImageView  isHidden   isChecked                    if selectedImageView    nil                selectedImageView  isHidden    isChecked                    self addTarget self  action   selector checkChanged       for   touchUpInside              objc func checkChanged   btn   UIButton           self isChecked    self isChecked          if defaultImageView    nil               defaultImageView  isHidden   isChecked                    if selectedImageView    nil                selectedImageView  isHidden    isChecked

You can simply subclass UIButton and write your own drawing code to suit your needs  I implemented a radio button like that of android using the following code  It can be used in storyboard as well See example in Github repo  import UIKit   IBDesignable class SPRadioButton  UIButton     IBInspectable var gap CGFloat   8       didSet           self setNeedsDisplay             IBInspectable var btnColor  UIColor   UIColor green      didSet          self setNeedsDisplay             IBInspectable var isOn  Bool   true      didSet          self setNeedsDisplay            override func draw   rect  CGRect        self contentMode    scaleAspectFill     drawCircles rect  rect        MARK - Draw inner and outer circles func drawCircles rect  CGRect       var path   UIBezierPath       path   UIBezierPath ovalIn  CGRect x  0  y  0  width  rect width  height  rect height        let circleLayer   CAShapeLayer       circleLayer path   path cgPath     circleLayer lineWidth   3     circleLayer strokeColor   btnColor cgColor     circleLayer fillColor   UIColor white cgColor     layer addSublayer circleLayer       if isOn           let innerCircleLayer   CAShapeLayer           let rectForInnerCircle   CGRect x  gap  y  gap  width  rect width - 2   gap  height  rect height - 2   gap          innerCircleLayer path   UIBezierPath ovalIn  rectForInnerCircle  cgPath         innerCircleLayer fillColor   btnColor cgColor         layer addSublayer innerCircleLayer            self layer shouldRasterize    true     self layer rasterizationScale   UIScreen main nativeScale       override func touchesBegan   touches  Set lt UITouch gt   with event  UIEvent         isOn    isOn     self setNeedsDisplay             override func awakeFromNib         super awakeFromNib       addTarget self  action   selector buttonClicked sender     for  UIControl Event touchUpInside      isOn   false     objc func buttonClicked sender  UIButton        if sender    self           isOn    isOn         setNeedsDisplay
