Port WMFAppViewController.m over to Swift, but do not change the method ordering or refactor to Coordinators. You may delete dead code but otherwise, maintain the same methods and ordering. This is so that it is easily review-able in a PR.
Main TestFlight 8.2.0 (latest)
Regression test launching app, article restoration, and deep linking.
Testing on 8.2.0 (6054)
I repeatedly encountered this error on all my test devices when tapping a lead image in an article. Tested in German and English on multiple articles. It is happening roughly 2/5 attempts. I have not identified any specific articles where it occurs 5/5 times. In most cases, the image will open as expected when retesting.
I think error above is an unrelated regression caused by server-side image URL changes, but noting the client-side PR fix for that issue here in case that clears things up for easier regression testing on this one.
