how to add fingerprint to app store

Adding fingerprint authentication to your iOS app is a great way to improve security by ensuring that only authorized users can access your app. In this article, we will show you how to add fingerprint authentication to your app store app.

First, you will need to create a new project in Xcode. To do this, launch Xcode and select the “Create a new Xcode project” option. Next, select the “Application” option, and then select the “iOS” option. Finally, select the “Single View Application” option and click “Next”.

In the next screen, enter the name of your project and select the language you want to use. For this example, we will use Swift. Click “Next”.

In the next screen, select the location where you want to save your project and click “Create”.

Next, you will need to add a fingerprint authentication key to your project. To do this, select the “Keys” tab in the project navigator and click the “Create a new key” button.

In the next screen, select the “Fingerprint Authentication” option and click “Next”.

In the next screen, enter a name for the key and click “Create”.

Next, you will need to add the fingerprint authentication code to your app. To do this, open the “ViewController.swift” file and add the following code:

import UIKit

import LocalAuthentication

class ViewController: UIViewController {

@IBOutlet weak var button: UIButton!

func authenticate() {

if LAContext.canEvaluatePolicy(.deviceOwnerAuthenticationWithBiometrics, nil) {

// User is already authenticated.

} else {

// User needs to be authenticated.

LAContext.requestDeviceAuthenticationWithBiometrics(

.deviceOwnerAuthenticationWithBiometrics,

description: “My App”,

localizedDescription: “My App”) {

(success, error) in

if success {

// User is authenticated.

} else {

// User was not authenticated.

}

}

}

}

}

In the code, we first check to see if the user is already authenticated. If the user is not authenticated, we request fingerprint authentication from the user. If the user is authenticated, we print a message to the console.

Next, you will need to add the following code to the “Info.plist” file:

NSFingerprintUsageDescription

My App needs your fingerprint to authenticate you.

This key tells the user why the app needs their fingerprint.

Finally, you will need to add the following code to the “Info.plist” file:

NSCalibratedTouchIdUsageDescription

My App needs your fingerprint to authenticate you.

This key tells the user why the app needs their fingerprint.

Now, you can run your app on a device or in the simulator and try out the fingerprint authentication.
