Undoubtedly, iPhones are the most updated smartphones in the world right now. There are many reasons why iPhones are always in demand throughout the world. Another advantage that iPhones have already given to the users is that the latest technology is available to the iOS users firstly in the market. No doubt about the fact that iOS devices come up with the latest technology and we recently saw iPhone X as well as iPhone XS. In this article, we are going to talk about Touch ID and Face ID which is the favorite of the users of the iPhones. So, more and more iOS application development companies are making it a point to integrate biometric authentication feature into the iPhone apps.

As we already know that the touch ID was already introduced in the iPhone 5S version, now is the time to make way for Face ID which will of course get famous as and when there are too many users of iPhone X also. Every app development company looks to integrate the best and the latest features and functionalities into the apps that are created by them for their clients.

Keeping this in view, we are heading towards discussing the ways using which the iPhone app developers can easily integrate the biometric authentication or verification in the apps and thus utilising this unique feature of the iPhones in general. It will ease the users as they will not need to remember the password of the apps, rather they can just use fingerprints or face ID to open any app. Therefore, if you have any app idea, hire iOS app developer who knows it well how to include this feature into the app.

We are very concerned about this fact that you need to hire app developer for iOS very carefully because some of the iOS developers have found it difficult to validate Touch ID on iOS 7, but because iOS 8 releases official API support for these applications, we are going to solve this problem.
In this tutorial, we first integrated the verification of the touch code into the iOS application.

Let’s firstly create a new project...
The first step is to create a new project from the File menu, and then select the Single View application. Then click Next. You will then get the interface as below. Then, you can go on with the next step as written below:

You will now need to name the project:
In the next step you need to name the project. For example, you can name it Biometrics as we have named here. Once the project has been successfully created, you can import the local certificate to ViewController.swift. More privacy permission to use Make sure that the Face ID privacy information must be generated in the project Info.plist file statement.

Checking the availability of the biometrics for authentication:
Wait a moment. The developer from the iOS application development company will now need to check the availability.

Did you check biometric authentication? 
This is the stage that all iOS devices do not have fingerprint scanning capabilities, and the integration of the touch code and face ID is not supported. It is therefore necessary first to confirm the existence of biometric authentication. This applies to the integrated touch tag and face tag.

Final verification of the biometric fingerprints or face biometrics:
Before continuing, it's important to check the availability of biometric data. If the device can support biometric sensors, consider setting up a fingerprint scan or face detection check. The following code is a good indication of whether the device supports ID and ID and updates the text of the authButton instance accordingly. When you hire iOS app developer, make sure that he knows it well that how he can utilise this very feature of the iPhones.

Import UIKs
At LocalAuthentication
Class ViewController: UIViewController {
/ / The first step is to define some of the features of the viewer on a global level.
@ IBOutlet Weak can imgAuthenticate: UIImageView!
  context = LAContext ().
  Can strAlertMessage = String ()
  VAR Error: NSError?
  Overrides func viewDidLoad (). {
    super.viewDidLoad ()
Contextual case
     Error: & error) {
context.canEvaluatePolicy (.deviceOwnerAuthenticationWithBiometrics, error: & error) {case
   Change context.biometryType {
     self.strAlertMessage = "Set face to authentication"
     self.imgAuthenticate.image = UIImage (name: "face")
   Case: TouchID:
     self.strAlertMessage = "Set finger for authentication"
     self.imgAuthenticate.image = UIImage (name: "touch")
   The thing is:
     Printing ("No")
     // description = "none"
Other {
    // The device cannot use biometric data
    If this is an error = error {
     // Call the error message function according to the type of error
        strMessage = self.errorMessage (errorCode: err._code).
        self.notifyUser ("Error"
                   Error: strMessage)
Other {
  If this is an error = error {
        strMessage = self.errorMessage (errorCode: err._code).
        self.notifyUser ("Error"
                   Error: strMessage)
Get biometric data from users
Once confirmed, it supports Touch Id, you can use the following command:
@IBAction func authenticateUser (_ sender: optional) {
/ / The device may use biometric data

Touch ID and Face ID are one of the most comfortable and attractive features of the latest iPhone. That's why users like it because they feel that their iPhone device is smarter and safer and every iOS application development company should provide this feature for the client apps . The users do not need to remember the password or lock mode to unlock the phone.
