Notice Google+ API is shutting down on March 7th, 2019.

Demonstration of how to use a bridging header for Google+ Sign-In (iOS and Swift).

There are two projects: one showing just Google+ Sign-in and the other showing how to use Google Play Games Services from Swift. The main difference between the two is that Google Play Games Services has additional callbacks and uses GPGManager wheras Google+ uses GPPSignin.

Note that the samples require the Google+ and Google Play Games SDK is uncompressed into the appropriate folder. Get them from the Google Play Games downloads page.

1. Get a client ID from https://console.deveopers.google.com for Google+ or from https://play.google.com/apps/publish for Google Play Games.
2. For the bundle ID, set it to com.gclassy.swiftsignin.
3. Copy the client ID into the Swift app in the ViewController.
4. Run the app.

1. Modify the bundle identifier in the project to something more appropriate for your domain / apps. Note You will need this value later.
2. Update the Scheme defined in the URL handlers in info.plist to match your bundle identifier. Note Don't skip this step.
3. Register your application with your bundle identifier on https://console.developers.google.com for Google+ or https://play.google.com/apps/publish for Google Play Games.
4. Copy the client ID into the Swift app in the ViewController.
5. Run the app and sign-in.

• If your application is failing after sign-in, you most likely have misconfigured your URL schemes in info.plist.
• If you are seeing an issue with the client not being configured, make sure you have set the bundle identifier correctly in the API console and that you have set the client ID correctly in your app.
• If you are getting a crash after the user signs in, you might need to add the account you are signin in as to the Plat Games console.
