Sign in with Apple Auth Provider

[dplewis]

Closes: #5632

Should work out of the box for linking users.

{
  "apple-signin": {
    "id_token": "jwt token for user", // required, used for validation
    "access_token": "an authorized access token for the user", // optional, currently does nothing but maybe in the future
  }
}

There is an optional client_id that you can pass in to Server Auth Configuration for extra validation.

{
  auth: {
   apple-signin: {
     client_id: "", // optional, use the Service ID from apple.
  }
}

There is a guide and code for setting getting your id_token https://developer.okta.com/blog/2019/06/04/what-the-heck-is-sign-in-with-apple

Apple's documentation is incomplete and incorrect in places

Shoutout to @Techofficer for doing most of the heaving lifting.

@dplewis Thanks a lot for taking the lead on this, I’ve spent the past couple hours setting it up in my app so I’m looking forward to testing this out!

[dplewis]

@TomWFox I post links above for configuration. Let me know if it works

[leapingcoyote]

We are getting this message, any idea what are we missing? Do you have some step by step setup and usage instructions. I feel we are missing a step. @TomWFox did it work for you?

{
    "message": "This authentication method is unsupported.",
    "code": 252
}

We have setup and api request from a server using this

    const user = new parse.User();
    return user._linkWith("apple-signin",
        {
            authData: authData
        }
    );

On our parse server config we are using this:

auth: {
    "apple-signin": {
      "client_id": "com.ourclient"
    }
  },

[dplewis]

@leapingcoyote This isn’t released yet, are you using the master branch to test?

[leapingcoyote]

@dplewis yes we are using the master branch to test

[dplewis]

Thanks for reporting. I’ll look into it

[dplewis]

@leapingcoyote I published a fix for this #5755

[tealshift]

@dplewis Hi, I'd like to ask about this update you added here. Is this update necessary for Apple Sign-In to work for an iOS client and save authData to MongoDB, or will we be okay using an older version of Parse Server?

[dplewis]

@tealshift You have to update to the latest version. If you don’t want to update. You can copy this and create your own module.
