The to-do list went to React, for the web, and to Swift, for the iPhone. We signed in, added a task, closed one with a note and restarted the app. At each step all three versions showed the same lists and saved the same changes.
The quiz game went to React. We made a new set of questions, renamed one, edited one and deleted one, then reloaded the page. The exported game kept exactly what the original keeps.
What’s left
A few parts don’t come across yet. In the to-do list, the dark colour theme and drag to reorder are two of them. Before it writes any code, the export lists every part it leaves out.
The Swift app has run in Apple’s iPhone simulator. Running it on a real phone and publishing it to the App Store are still to come.
