Getting Started

Requirements

  • iOS 12.0+ / macOS 10.15+ / tvOS 12.0+ / watchOS 6.2+
  • Xcode 13.x / 14.x
  • Swift 5.3+

Note Check the Support Policy to learn when dropping Xcode, Swift, and platform versions will not be considered a breaking change.

Installation

Swift Package Manager

Open the following menu item in Xcode:

File > Add Packages...

In the Search or Enter Package URL search box enter this URL:

https://github.com/auth0/Auth0.swift

Then, select the dependency rule and press Add Package.

Cocoapods

Add the following line to your Podfile:

pod 'Auth0', '~> 2.3'

Then, run pod install.

Carthage

Add the following line to your Cartfile:

github "auth0/Auth0.swift" ~> 2.3

Then, run carthage bootstrap --use-xcframeworks.

Configure the SDK

Head to the Auth0 Dashboard and create a new Native application.

Auth0.swift needs the Client ID and Domain of the Auth0 application to communicate with Auth0. You can find these details in the settings page of your Auth0 application. If you are using a custom domain, use the value of your custom domain instead of the value from the settings page.

Configure Client ID and Domain with a plist

Create a plist file named Auth0.plist in your app bundle with the following content:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>ClientId</key>
    <string>YOUR_AUTH0_CLIENT_ID</string>
    <key>Domain</key>
    <string>YOUR_AUTH0_DOMAIN</string>
</dict>
</plist>

Configure Client ID and Domain programmatically

For Web Auth
Auth0
    .webAuth(clientId: "YOUR_AUTH0_CLIENT_ID", domain: "YOUR_AUTH0_DOMAIN")
    // ...
For the Authentication API client
Auth0
    .authentication(clientId: "YOUR_AUTH0_CLIENT_ID", domain: "YOUR_AUTH0_DOMAIN")
    // ...
For the Management API client (Users)
Auth0
    .users(token: credentials.accessToken, domain: "YOUR_AUTH0_DOMAIN")
    // ...

Configure Web Auth (iOS / macOS)

Configure callback and logout URLs

The callback and logout URLs are the URLs that Auth0 invokes to redirect back to your app. Auth0 invokes the callback URL after authenticating the user, and the logout URL after removing the session cookie.

Since callback and logout URLs can be manipulated, you will need to add your URLs to the Allowed Callback URLs and Allowed Logout URLs fields in the settings page of your Auth0 application. This will enable Auth0 to recognize these URLs as valid. If the callback and logout URLs are not set, users will be unable to log in and out of the app and will get an error.

Go to the settings page of your Auth0 application and add the corresponding URL to Allowed Callback URLs and Allowed Logout URLs, according to the platform of your app. If you are using a custom domain, replace YOUR_AUTH0_DOMAIN with the value of your custom domain instead of the value from the settings page.

iOS
YOUR_BUNDLE_IDENTIFIER://YOUR_AUTH0_DOMAIN/ios/YOUR_BUNDLE_IDENTIFIER/callback
macOS
YOUR_BUNDLE_IDENTIFIER://YOUR_AUTH0_DOMAIN/macos/YOUR_BUNDLE_IDENTIFIER/callback

For example, if your iOS bundle identifier was com.example.MyApp and your Auth0 Domain was example.us.auth0.com, then this value would be:

com.example.MyApp://example.us.auth0.com/ios/com.example.MyApp/callback

Note Make sure that the Token Endpoint Authentication Method setting is set to None.

Configure custom URL scheme

Back in Xcode, go to the Info tab of your app target settings. In the URL Types section, click the button to add a new entry. There, enter auth0 into the Identifier field and $(PRODUCT_BUNDLE_IDENTIFIER) into the URL Schemes field.

url-scheme

This registers your bundle identifier as a custom URL scheme, so the callback and logout URLs can reach your app.

Web Auth login (iOS / macOS)

Import the Auth0 module in the file where you want to present the login page.

import Auth0

Then, present the Universal Login page in the action of your Login button.

Auth0
    .webAuth()
    .start { result in
        switch result {
        case .success(let credentials):
            print("Obtained credentials: \(credentials)")
        case .failure(let error):
            print("Failed with: \(error)")
        }
    }
Using async/await
do {
    let credentials = try await Auth0.webAuth().start()
    print("Obtained credentials: \(credentials)")
} catch {
    print("Failed with: \(error)")
}
Using Combine
Auth0
    .webAuth()
    .start()
    .sink(receiveCompletion: { completion in
        if case .failure(let error) = completion {
            print("Failed with: \(error)")
        }
    }, receiveValue: { credentials in
        print("Obtained credentials: \(credentials)")
    })
    .store(in: &cancellables)

Web Auth logout (iOS / macOS)

Logging the user out involves clearing the Universal Login session cookie and then deleting the user's credentials from your app.

Call the clearSession() method in the action of your Logout button. Once the session cookie has been cleared, delete the user's credentials.

Auth0
    .webAuth()
    .clearSession { result in
        switch result {
        case .success:
            print("Session cookie cleared")
            // Delete credentials
        case .failure(let error):
            print("Failed with: \(error)")
        }
    }
Using async/await
do {
    try await Auth0.webAuth().clearSession()
    print("Session cookie cleared")
    // Delete credentials
} catch {
    print("Failed with: \(error)")
}
Using Combine
Auth0
    .webAuth()
    .clearSession()
    .sink(receiveCompletion: { completion in
        switch completion {
        case .finished:
            print("Session cookie cleared")
            // Delete credentials
        case .failure(let error):
            print("Failed with: \(error)")
        }
    }, receiveValue: {})
    .store(in: &cancellables)

SSO alert box (iOS / macOS)

sso-alert

Check the FAQ for more information about the alert box that pops up by default when using Web Auth.

Support Policy

This Policy defines the extent of the support for Xcode, Swift, and platform (iOS, macOS, tvOS, and watchOS) versions in Auth0.swift.

Xcode

The only supported versions of Xcode are those that can be currently used to submit apps to the App Store. Once a Xcode version becomes unsupported, dropping it from Auth0.swift will not be considered a breaking change, and will be done in a minor release.

Swift

The minimum supported Swift minor version is the one released with the oldest-supported Xcode version. Once a Swift minor becomes unsupported, dropping it from Auth0.swift will not be considered a breaking change, and will be done in a minor release.

Platforms

Only the last 4 major platform versions are supported, starting from:

  • iOS 12
  • macOS 10.15
  • macCatalyst 13
  • tvOS 12
  • watchOS 6.2

Once a platform version becomes unsupported, dropping it from Auth0.swift will not be considered a breaking change, and will be done in a minor release. For example, iOS 13 will cease to be supported when iOS 17 gets released, and Auth0.swift will be able to drop it in a minor release.

In the case of macOS, the yearly named releases are considered a major platform version for the purposes of this Policy, regardless of the actual version numbers.
