Introduction to How to create check box in swift – tutorial
In iOS, there is no default UIControl for creating a check box button. Thus we have to create our own check box in iOS app development, to use in our iOS apps by using other UIControl’s like UIButton. In this tutorial, we will learn how to create a check box using swift in ios sdk and also animating it while changing checkbox state from un-selected one to selected one and vice versa.

Step 5: Add the assets/images to your projects “Assets.xcassets”.
Step 6: Open “ViewController.swift”, and create an IBOutlet for the button which is going to be used as check box for our app. Also we will assign our image/assets to button, un-selected checkbox image is assigned to default/normal state of UIButton and selected checkbox image is assigned to selected state of UIButton. Lastly, we will create an IBAction for UIButton so that we can detect the touch event,
Step 7: Open “Main.storyboard” and connect IBOutlet and IBaction(touchupinside event) to button.
Step 8: Also change button type and remove title as shown in the image below
Step 9: Open “ViewController.swift” so that we can add code inside our IBAction “checkMarkTapped” , in order to make btnCheckMark behave like a Checkbox. Below is the code
Step 10: Run your app and tap on Button with green circle image, you will see checkbox on or off / selected or UN-selected.
