Sign in with Apple
This guide will teach you how to add native Sign in with Apple to your Clerk apps on Apple platforms.
Configure the Apple social connection
To support native Sign in with Apple, you need to configure the Apple social connection in the Clerk Dashboard. To do so, follow the native-specific instructions in the OAuth with Apple guide.
Add the Sign in with Apple capability to your app

Obtain an Apple ID Credential
To authenticate with Apple and Clerk, you need to obtain an Apple ID Credential.
To obtain an Apple ID Credential, you can do one of the following:
- Use one of Apple's built-in Sign in with Apple buttons.
- Obtain it manually by following the Apple docs
Build your sign-in flow
Once you have obtained your Apple ID Credential, you can use it to authenticate with Clerk by calling SignIn.create(strategy:) with a strategy of .idToken followed by .authenticateWithIdToken().
The following example uses Apple's built-in SignInWithAppleButton to obtain an Apple ID Credential and calls SignIn.create(strategy:) and .authenticateWithIdToken() to authenticate with Clerk.
import SwiftUI
import ClerkSDK
import AuthenticationServices
struct SignInWithAppleView: View {
var body: some View {
// Use Apple's built-in SignInWithAppleButton
SignInWithAppleButton { request in
request.requestedScopes = [.email, .fullName]
request.nonce = UUID().uuidString // Setting the nonce is mandatory
} onCompletion: { result in
Task {
// Access the Apple ID Credential
guard let credential = try result.get().credential as? ASAuthorizationAppleIDCredential else {
dump("Unable to get credential of type ASAuthorizationAppleIDCredential")
return
}
// Access the necessary identity token on the Apple ID Credential
guard let idToken = credential.identityToken.flatMap({ String(data: $0, encoding: .utf8) }) else {
dump("Unable to get ID token from Apple ID Credential.")
return
}
// Authenticate with Clerk
let authResult = try await SignIn
.create(strategy: .idToken(provider: .apple, idToken: idToken))
.authenticateWithIdToken()
}
}
}
