Microsoft Authentication Library B2C Sample for Apple iOS in Swift

Getting Started	Library	Docs	Support

The MSAL library for iOS and macOS gives your app the ability to begin using the Microsoft identity platform by supporting Azure B2C using industry standard OAuth2 and OpenID Connect. This sample demonstrates all the normal lifecycles your application should experience, including:

How to get a token
How to refresh a token
How to call your backend REST API service
How to clear your user from your application

Example

do {
	// Create an instance of MSALPublicClientApplication with proper config
	let authority = try MSALB2CAuthority(url: URL(string: "<your-authority-here>")!)
	let pcaConfig = MSALPublicClientApplicationConfig(clientId: "<your-client-id-here>", redirectUri: nil, authority: authority)
	let application = try MSALPublicClientApplication(configuration: pcaConfig)
            
	let viewController = self /*replace with your main presentation controller here */
	let webViewParameters = MSALWebviewParameters(authPresentationViewController: viewController)
	let interactiveParameters = MSALInteractiveTokenParameters(scopes: ["<enter-your-scope-here>"], webviewParameters: webViewParameters)
            
	application.acquireToken(with: interactiveParameters) { (result, error) in
                
		guard let result = result else {
			print(error!) /* MSAL token acquisition failed, check error information */
			return
                }
                
                let accessToken = result.accessToken
                let account = result.account
                /* MSAL token acquisition succeeded, use access token or check account */
                
	}
}
catch {
	print(error) /* MSALPublicClientApplication creation failed, check error information */
}

App Registration

You will need to have a B2C client application registered with Microsoft. Follow the instructions here. Make sure you make note of your client ID, and the name of the policies you create. Once done, you will need add the redirect URI of msal<your-client-id-here>://auth.

Installation

Load the podfile using cocoapods. This will create a new XCode Workspace you will load.

From terminal navigate to the directory where the podfile is located

$ pod install
...
$ open MSALiOSB2C.xcworkspace

⚠️ Note: If using an ARM-based Mac (M1/M2) then pod install needs to be run in a Rosetta terminal window. For more information follow the instructions here.

Configure your application

Add your application's redirect URI scheme to added in the portal to your info.plist file. It will be in the format of msal<client-id>

    <key>CFBundleURLTypes</key>
    <array>
        <dict>
            <key>CFBundleTypeRole</key>
            <string>Editor</string>
            <key>CFBundleURLName</key>
            <string>$(PRODUCT_BUNDLE_IDENTIFIER)</string>
            <key>CFBundleURLSchemes</key>
            <array>
                <string>msalyour-client-id-here</string>
            </array>
        </dict>
    </array>

Configure your application defaults

In the ViewControler.swift file, update the variables at the top of this file with the information for your tenant.

    let kTenantName = "fabrikamb2c.onmicrosoft.com" // Your tenant name
    let kAuthorityHostName = "fabrikamb2c.b2clogin.com" // Your authority host name
    let kClientID = "Enter_the_Application_Id_Here" // Your client ID from the portal when you created your application
    let kSignupOrSigninPolicy = "b2c_1_susi" // Your signup and sign-in policy you created in the portal
    let kEditProfilePolicy = "b2c_1_edit_profile" // Your edit policy you created in the portal
    let kResetPasswordPolicy = "b2c_1_reset" // Your reset password policy you created in the portal
    let kGraphURI = "https://fabrikamb2chello.azurewebsites.net/hello" // This is your backend API that you've configured to accept your app's tokens
    let kScopes: [String] = ["https://fabrikamb2c.onmicrosoft.com/helloapi/demo.read"] // This is a scope that you've configured your backend API to look for.

Security Library

This library controls how users sign-in and access services. We recommend you always take the latest version of our library in your app when possible. We use semantic versioning so you can control the risk associated with updating your app. As an example, always downloading the latest minor version number (e.g. x.y.x) ensures you get the latest security and feature enhanements but our API surface remains the same. You can always see the latest version and release notes under the Releases tab of GitHub.
