Wonder Workshop no longer provides updates to the Swift Playground interface. However, you may be able to still interact with the app by performing the following steps. 

1. Launch Swift Playgrounds

2. There's a bar on the bottom that says "More Playgrounds", with a "See All" link on the right side of the bar, tap on "See All"

3. Scroll down, you should see a section called "Wonder Workshop", with a playground called "Dash", tap on the "GET" button to get this particular playground.

Backup in case the "Wonder Workshop" section is missing:

3b. At step 3, scroll down all the way to the bottom of the page, find a link that says "Enter a Subscription URL", tap on it.

4. In the modal that pops up, enter the URL "swiftplaygrounds.makewonder.com/locales.json", then tap "Subscribe"

5. You should get a confirmation modal asking if you trust us.  Tap on "Subscribe".

6. Swift Playgrounds should now download the Dash and Dash Template, and they should be available under the "More Playgrounds" section of the app.
