A library written in Swift for authenticating with LinkedIn using OAuth2.

The LinkedIn iOS SDK is broken by default because it forces the user to have the LinkedIn app installed on their device. This library abstracts the authentication flow using LinkedIn's OAuth2 API in an embeded WKWebView within the app.

Add the following line to your Cartfile:

github "gabrielvincent/LinkedInAuth-Swift"

A sample app is available at https://github.com/gabrielvincent/LinkedInAuth-SampleApp

Make sure you have an app created in you LinkedIn developer account (https://www.linkedin.com/developers/apps). There you'll be able to get your client id, client secret and set the redirect URI.

First, create a configuration object:

let liAuthConfiguration = LinkedInAuthConfiguration(WithClientID: "YOUR_LINKEDIN_CLIENT_ID",
                                                    clientSecret: "YOUR_LINKEDIN_CLIENT_SECRET",
                                                    redirectURI: "https://your_redirect_uri.com",
                                                    scope: [.BasicProfile, .EmailAddress],
                                                    state: nil)

Then, use those configurations to begin the authentication flow:

LinkedInAuth.manager.authenticate(WithConfiguration: liAuthConfiguration, success: { (accessToken) in
            
    print("Did get access token: \(accessToken)")
    
    // Now you can use this access token to make API calls.
    
}) { (error) in
    
    print("Didn't get access token: \(error.localizedDescription)")
}

A UIViewController will be presented modally containing the WKWebView that will handle the authentication flow:

This library doesn't require a working URI endpoint in order to get the authorization code returned after the user authorizes your app. The authorization code is captured by the WKWebView instance presenting the authentication dialog. Still, a valid URI is required by LinkedIn.
