Write a Combine pipeline that sends two different network requests (user profile, account list) at the same time and emits a result once, only when both have completed. Would you use zip or combineLatest, and why?
Use zip to pair two one-shot requests. zip matches the nth value from each upstream and emits once, only when both have arrived, while combineLatest re-emits the latest combination whenever either side changes after both have emitted once, so the meaning differs. Zip the profile and accounts publishers, map them into a dashboard model, receive on main, and sink.
