AppAuth Example Project using Swift

The example doesn't work out of the box, you need to configure it your own client ID.

To configure the sample with a Google OAuth client, visit https://console.developers.google.com/apis/credentials?project=_ and create a new project. Then tap "Create credentials" and select "OAuth client ID". Follow the instructions to configure the consent screen (just the Product Name is needed).

Then, complete the OAuth client creation by selecting "iOS" as the Application type. Enter the Bundle ID of the project (net.openid.appauth.Example by default, but you may want to change this in the project and use your own Bundle ID).

Copy the client ID to the clipboard.

In AppAuthSwiftSampleViewController.swift update kClientID with your new client id.

In the same file, update kRedirectURI with the reverse DNS notation form of the client ID. For example, if the client ID is YOUR_CLIENT.apps.googleusercontent.com, the reverse DNS notation would be com.googleusercontent.apps.YOUR_CLIENT. A path component is added resulting in com.googleusercontent.apps.YOUR_CLIENT:/oauthredirect.

Finally, open Info.plist and fully expand "URL types" (a.k.a. "CFBundleURLTypes") and replace com.googleusercontent.apps.YOUR_CLIENT with the reverse DNS notation form of your client id (not including the :/oauthredirect path component).

Once you have made those three changes, the sample should be ready to try with your new OAuth client.
