How to implement sign in with apple button in swiftui?


Asked by Ember McConnell on Dec 12, 2021 FAQ



As of now, the Sign in with Apple button and user interface flow is available for implementation only using a view controller in UIKit. Hence, we’ll create a SwiftUI view for the Sign in with Apple button using UIViewRepresentable, and use the ASAuthorizationController by creating a new class and initialising it in our observable model class.
Thereof,
Apple recently updated Swift UI so that integrating Sign In With Apple through it is as seamless as it gets. This and all other new SwiftUI improvements are an indication that Apple is taking seriously the new state-driven, reactive, and declarative way of creating Apple apps.
In this manner, It’s very easy to create a button using SwiftUI. Basically, you can use the code snippet below to create a button: When creating a button, you need to provide two code blocks: What to perform — the code to perform after the button is tapped or selected by the user.
Additionally,
Click the project in the Project navigator, select the SignInWithApple target and then click the Signing & Capabilities tab. Finally, click + Capability and add the Sign In with Apple capability. If your app has an associated website, you should also add the Associated Domains capability.
And,
You subclass UIViewRepresentable when you need to wrap a UIView. makeUIView should always return a specific type of UIView. Since you’re not performing any customization, you return the Sign In with Apple object directly.
