Progress so far

• Opened a draft PR with a test implementation of the "recommend comment" feature on ios-live as an example
  • interaction with Bridget/DCAR webview is working
• Next steps: Create modules to interact with Discussion API in exactly the way we want. The existing implementation is tightly coupled. It uses native views and handles errors using native UI.
  • We want to pass errors from DAPI to the webview in Bridget's completion callback
  • Useful example modules are from the Personalisation team's MyGuardian implementation. These follow more modern Swift patterns: TagService, ContributorFollower.follow, MyGuardianPreferences

Working on this locally

• Check out gb/bridget-discussion on ios-live
• Check out gb/dcar-discussion-beta on MAPI, and run mobile fronts
• Check out gb/test-recommend-ios on DCR and run the dev server
• Set debug settings in iOS simulator to use CODE Okta, CODE Identity, Local AR, Local MAPI fronts. Make sure you're not using the new Blueprint fronts! These don't work with beta articles

Open questions

• Decide the "sign in" behaviour should work
• What should the failure mode be if the user goes offline?
