SocialLogins

Enable iOS app Sign in with Apple, Twitter, Facebook, Google and LinkedIn with ease. It will really saves you a lot of hours.

The origin is a reference to the struct AppleUserModel, GoogleUserModel, FacebookUserModel , TwitterUserModel and LinkedInUserModel. For Google it has the property user that reference to GIDGoogleUser which you could use for any other Google APIs. While for Twitter, it has an OAuthToken to be use on other Twitter APIs.

Installation

You just need to drag and drop respective social login folder to your project.

Open your AppDelegate.swift file, and add these codes

func application(_ application: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey: Any] = [:]) -> Bool  {
    if url.absoluteString.contains("google") {
        return GoogleSignInHelper.openURL(url)
    } else if url.absoluteString.contains("fb") {
        return FacebookSignInHelper.openURL(app: application, url: url, options: options)
    } else if url.absoluteString.contains("twitterkit-") {
        return TwitterSignInHelper.openURL(url)
    } else if url.absoluteString.contains("linkedin") {
        return  LinkedInSignInHelper.openURL(url)
    }
    return  true
}

Usage

Implementing Google Sign In

Get the Google Client ID and Scheme Path URL from Google API Console. You may follow the tutorial at Google Sign In to get those. Put your Scheme Path URL to the URL Scheme configuration on Xcode.

And on your Google Sign In button action, specify with the code:

GoogleSignInHelper.shared.login(with: SocialCredentials.Google.clientId, from: self) { (error, user) in
    if let user = user {
        print(user)
    } else {
        print(error ?? "Unknown Error")
    }
}

Implementing Facebook Sign In

Setup an app on Facebook Developer Portal, and get the Facebook App ID. Put your App ID on the Info.plist file:

<key>FacebookAppID</key>
<string>13434434</string>

Put fb-your-fb-app-id- on URL Scheme. If your App ID is 13434434, then fb13434434 need to be on your URL Scheme. Put the fbauth2 on your URL Scheme as well.

And on your Facebook Sign In button action, specify with the code:

FacebookSignInHelper.shared.login(from: self) { (error, user) in
    if let user = user {
        print(user)
    } else {
        print(error ?? "Unknown Error")
    }
}

Implementing Twitter Sign In

Go to Twitter Developer Portal and get Twitter App Key and Twitter App Secret. Put the twitterkit-your-appkey- to URL Scheme. If your app key is 1212 the put twitterkit-1212.

And on your Twitter Sign In button action, specify with the code:

TwitterSignInHelper.shared.login(with: SocialCredentials.Twitter.kAPIKey, and: SocialCredentials.Twitter.kAPISecret) { (error, user) in
    if let user = user {
        print(user)
    } else {
        print(error ?? "Unknown Error")
    }
}

Implementing Apple Sign In

On XCode, go to Signing & Capabilities tab. Enable Sign In with Apple there.

And on your Apple Sign In button action, specify with the code:

if  #available(iOS 13, *) {
    AppleSignInHelper.shared.login(from: self) { (error, user) in
        if let user = user {
            print(user)
        } else {
            print(error ?? "Unknown Error")
        }
    }
} else {
    // Fallback on earlier versions
    print("Sign in with Apple require iOS 13 and later")
}

Implementing LinkedIn Sign In

You need to add supported library for it as follow:

• Podfile

platform :ios, '10.0'
use_frameworks!

pod 'OAuthSwift', '~> 2.0.0'

Setting URL Schemes

In info tab of your target Replace oauth-swift by your application name

LinkedIn is not supporting custom URL Scheme as callback url. it is only allowing protocol http or https. So you need to make one callback URL on server which redirects to your URL Scheme i.e oauth-swift.

You can find sample php file named callback.php in LinkedInSignInHelper directory.

And on your LinkedIn Sign In button action, specify with the code:

LinkedInSignInHelper.shared.login(with: SocialCredentials.LinkedIn.clientId, and: SocialCredentials.LinkedIn.clientSecret, redirectUrl: "http://localhost:8080/callback.php", viewController: self) { (error, user) in
    if let user = user {
        print(user)
        print(user.profilePictureUrls)
    } else {
        print(error ?? "Unknown Error")
    }
}
