With this, users using an Apple account can sign-in on an application with a hassle free easy process. It is a fast and private way to sign-in into the apps which will give people the convenience and trust with the experience.<\/span><\/p>\n\n\n\n Apple sign authenticates via a Face ID or Biometrics with single button tap and also offers two factor authentication if a user has set up that in their account. Now, Apple is making a mandatory requirement of implementing Apple Sign-in on all the applications that implement google, facebook or twitter sign-in functionality.<\/span> Hire swift developers<\/a><\/strong> for your iOs devices.<\/p>\n\n\n\n Process of implementing Apple sign in apple id<\/span> on an application:<\/span><\/p>\n\n\n\n In this step, you will be able to retrieve Apple credentials for the user.<\/p>\n\n\n\n It will look like this on implementation:<\/p>\n\n\n\n While implementation, you might notice that you will get Nil value for Email and Name after signing in. This is due to Apple restricting the app to only get the user data once on the first signing attempt. So to overcome this, you need to save the credentials you received on the first Signing attempt on User Defaults or Cloud Server you use for your application.<\/span><\/p>\n\n\n\nWhat is Sign-in with Apple in iOS Devices?<\/b><\/h2>\n\n\n\n

<\/figure>\n\n\n\n2. Add sign-in with apple button programmatically:<\/h3>\n\n\n\n
Import<\/span> AuthenticationServices<\/em><\/span>\n\nfunc<\/strong> setUpSignInAppleButton() {<\/span>\n\n let<\/strong> authorizationButton = ASAuthorizationAppleIDButton()<\/span>\n\n authorizationButton.addTarget(self<\/strong>, action:<\/span>\n\n#selector<\/strong>(handleAppleIdRequest), for: .touchUpInside)<\/span>\n\nauthorizationButton.cornerRadius = 10\n\n<\/span>\n\n \/\/Add button on some view or stack<\/strong><\/span>\n\nself<\/strong>.signInButtonStack.addArrangedSubview(authorizationButton)}<\/span>\n\n<\/code><\/div><\/code><\/pre>\n\n\n\n3.
