Push Notifications Console: Apple’s Sport-Altering New Software

At WWDC ’23, Apple introduced the Push Notifications Console, a much-needed new software to simplify creating and testing your push notifications.

For years, builders have struggled with push notifications. Every developer needed to write customized scripts to not solely generate the suitable payload, but additionally deal with the authentication to APNs. In later years, Apple simplified the method by permitting the simulator to set off a notification by dropping in a JSON payload.

Due to the Push Notifications Console, now you can say goodbye to these clunky, outdated strategies. However first, you’ll check out how push notifications have labored thus far.

Sending Push Notifications — the Outdated Method

Till now, once you wanted push notifications, you’ve in all probability written a script with code like this:

operate generateAuthenticationHeader()
{
  $header = base64_encode(json_encode(['alg' => 'ES256', 'kid' => AUTH_KEY_ID]));
  $claims = base64_encode(json_encode(['iss' => TEAM_ID, 'iat' => time()]));

  $pkey = openssl_pkey_get_private('file://' . AUTH_KEY_PATH);
  openssl_sign("$header.$claims", $signature, $pkey, 'sha256');

  $signed = base64_encode($signature);

  return "$header.$claims.$signed";
}

operate sendNotifications($token, $debug) {
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_2_0);
  curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($GLOBALS['payload']));
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($ch, CURLOPT_HTTPHEADER, [
      'apns-topic: ' . BUNDLE_ID,
      'authorization: bearer ' . generateAuthenticationHeader(),
      'apns-push-type: alert'
  ]);

  $server = $debug ? 'api.growth' : 'api';
  $url = "https://$server.push.apple.com/3/system/$token";
  curl_setopt($ch, CURLOPT_URL, "{$url}");

  $response = curl_exec($ch);
  if ($response === false) {
    echo("curl_exec failed: " . curl_error($ch));
    proceed;
  }

  $code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
  if ($code === 400 || $code === 410) {
    $json = @json_decode($response);
    if ($json->motive === 'BadDeviceToken') {
        // Do one thing right here.
    }
  }

  curl_close($ch);
}

Whereas that works, it isn’t fairly.

Numerous apps from the Mac App Retailer additionally promise to make push notifications simpler, however they steadily don’t sustain with modifications to the APN’s packet format and headers it’s possible you’ll want to use.

Now, you’ll check out the Push Notifications Console and the way it improves push notification testing.

The New Push Notifications Console

To attempt Apple’s new software, level Safari to the CloudKit Console and click on the brand new Push Notifications merchandise:

In case your app isn’t configured to obtain push notifications, you’ll have the choice to allow them:

In case you have multiple app configured within the developer portal, choose the suitable one from the drop-down on the top-left of the web page.

Clicking Create New Notification will current you with a display permitting you to simply configure the notification you want to ship:

The brand new console makes it easy to supply all of the required configuration settings. It additionally clearly reveals the 4 objects that should be despatched as HTTP headers, versus a part of the payload.

Configuring the Payload

Apple gives a pleasant set of defaults for the payload configuration, enabling you to enter easy messages quickly. In case you have already ready a customized JSON payload, you may simply toggle the JSON View swap, then paste in your payload instantly:

Not solely does the console validate that you just’ve supplied correct JSON, nevertheless it additionally notifies you if the payload doesn’t appear to adapt to the apns-push-type you chose.

You possibly can toggle the JSON View on and off to change between codecs. An excellent technique is to make use of the default view to enter a lot of the information, then swap to the JSON view when getting into an array of things to scale back the quantity of mouse-clicking it is advisable to do.

Debugging With the Supply Log

One other nice characteristic now out there to builders is the supply log. After sending your notification, this characteristic will instantly current you with a web page displaying the small print of the despatched notification in addition to the log:

The logs will show you how to determine not solely whether or not or not the push notification was profitable, but additionally why it wasn’t delivered on failure.

By no means earlier than have builders had such a easy methodology of debugging push notification points!
