Official Clerk iOS SDK (Beta)

Clerk helps developers build user management. We provide streamlined user experiences for your users to sign up, sign in, and manage their profile.

ℹ️ While minor breaking changes (method names, parameter names, etc.) can be expected until version 1.0.0, the iOS SDK is considered stable.

🚀 Get Started with Clerk

1. Sign up for an account
2. Create an application in your Clerk dashboard
3. Spin up a new codebase with the quickstart guide

🧑‍💻 Installation

Swift Package Manager

To integrate using Apple's Swift Package Manager, navigate to your Xcode project, select Package Dependencies and click the + icon to search for https://github.com/clerk/clerk-ios.

Alternatively, add the following as a dependency to your Package.swift:

dependencies: [
    .package(url: "https://github.com/clerk/clerk-ios", from: "0.1.0")
]

🛠️ Usage

First, configure Clerk in your app's entry point:

import SwiftUI
import Clerk

@main
struct ClerkQuickstartApp: App {
  @State private var clerk = Clerk.shared

  var body: some Scene {
    WindowGroup {
      ContentView()
        .environment(clerk)
        .task {
          clerk.configure(publishableKey: "your_publishable_key")
          try? await clerk.load()
        }
    }
  }
}

Now in your views, you can conditionally render content based on the user's session:

import SwiftUI
import Clerk

struct ContentView: View {
  @Environment(Clerk.self) private var clerk

  var body: some View {
    VStack {
      if let user = clerk.user {
        Text("Hello, \(user.id)")
      } else {
        Text("You are signed out")
      }
    }
  }
}

Authentication

Sign Up with Email and Perform Verification

// Create a sign up
var signUp = try await SignUp.create(
  strategy: .standard(emailAddress: "[email protected]", password: "••••••••••••")
)

// Check if the SignUp needs the email address verified and send an OTP code via email.
if signUp.unverifiedFields.contains("email_address") {
  signUp = try await signUp.prepareVerification(strategy: .emailCode)
}

// After collecting the OTP code from the user, attempt verification
signUp = try await signUp.attemptVerification(strategy: .emailCode(code: "12345"))

Passwordless Sign In

// Create the sign in
var signIn = try await SignIn.create(
  strategy: .identifier("[email protected]", strategy: "email_code")
)
      
// After collecting the OTP code from the user, attempt verification
signIn = try await signIn.attemptFirstFactor(for: .emailCode(code: "12345"))

Sign In with OAuth (e.g. Google, Github, etc.)

try await SignIn.authenticateWithRedirect(strategy: .oauth(provider: .google))

Native Sign in with Apple

// Use the Clerk SignInWithAppleHelper class to get your Apple credential
let credential = try await SignInWithAppleHelper.getAppleIdCredential()

// Convert the identityToken data to String format
guard let idToken = credential.identityToken.flatMap({ String(data: $0, encoding: .utf8) }) else { return }

// Authenticate with Clerk
try await SignIn.authenticateWithIdToken(provider: .apple, idToken: idToken)

Forgot Password

// Create a sign in and send an OTP code to verify the user owns the email.
var signIn = try await SignIn.create(
  strategy: .identifier("[email protected]", strategy: "reset_password_email_code")
)

// After collecting the OTP code from the user, attempt verification.
signIn = try await signIn.attemptFirstFactor(for: .resetPasswordEmailCode(code: "12345"))

// Set a new password to complete the process.
signIn = try await signIn.resetPassword(.init(password: "••••••••••••", signOutOfOtherSessions: true))

Sign Out

try await clerk.signOut()

User Management

Update User Profile

try await user.update(.init(firstName: "John", lastName: "Appleseed"))

Update User Profile Image

let imageData = try await photosPickerItem.loadTransferable(type: Data.self)
try await user.setProfileImage(imageData: imageData)

Link an External Account

let externalAccount = try await user.createExternalAccount(provider: .github)
try await externalAccount.reauthorize()
