This tutorial outlines the steps to add Touch ID and Face ID to your iOS app.

Step 1: Create a new project

Open the XCode and single view app and give a product name as ‘TouchIDProtectedApp’ and select the location where you want to save the app.

Step 2: Add UI elements

• Click on the bottom right button on the below screenshot, which will allow you to add a navigation controller to the main ViewController of the app.
• Add a button object to the storyboard from the UI element list and change the button text to ‘Click here to Authenticate’.
• If needed, edit the button properties (optional).

Step 3: Create button Action and Add the properties

• As shown in the below screenshot, add the action of the button created in step 2 to the viewController (Make sure that the connection is Action).
• Use the name: ‘verification’
• Select Event as ‘Touch Inside’
