Integrating Sign in with Apple in an Ionic 3+ mobile app

Apple has instituted a new policy whereby if your app uses any method of “social login”, it is mandatory to also support “Sign in with Apple”.

There are great resources available from Apple themselves if you’re creating a web platform or a mobile app. However, if you are creating a hybrid app, then it might be a little trickier than initially meets the eye.

The web version “applesigninjs” redirects the user away from your app and you can’t get back to your app once the “Sign in with Apple” has run its course. This means it isn’t a viable option for a hybrid app.

If you are struggling to incorporate this and have an urgent app update to push up, don’t worry. Let me take you through how I implemented this.

There are a few Cordova plugins out there, but they aren’t all currently maintained and a few of them have unresolved Git issues – which makes the prospect of using one a bit daunting.

Thankfully, after trying a few of the existing Cordova plugins, I managed to come right with this one: https://github.com/nrikiji/cordova-signin-with-apple-plugin#readme

As per usual, you can add this to your project with a simple: 


cordova plugin add cordova-signin-with-apple-plugin


After installing the plugin and building your project, you might find the following error:


window.signinWithApple is not defined


Don’t worry, to resolve this, simply add the following declaration to the top of your file:

declare var window: any;


After that, everything should work as per the documentation. Essentially, you can include the something like the following:


window.signinWithApple.auth({
        scopes: “fullName, email”
      }, function(result) {
       
      }, function(err) {
       
      });


Just a few things to keep in mind:

    1. This only works for iOS13+
    2. Sign in with Apple allows the user to hide their e-mail address, which means Apple will return a proxy e-mail address. You will need to consider how you handle this architecturally.

 


Happy coding!
