From Dieter Bohn at The Verge:
Something keeps coming up at the Epic v. Apple trial as a potential alternative for getting Fortnite on the iPhone: web apps. It’s an intriguing idea, as web apps are able to do surprisingly complex things: just look at a Chromebook or even game streaming services on the iPhone. But potential is far from reality, because the ability for web apps to look, feel, and perform as well as native apps on iOS is severely limited.
Another good breakdown of the issues Apple is trying to have both ways. They’re keeping a tight grip on their App Store and saying that Web Apps are a path forward if you don’t like it, but then they’re making it difficult for folks to actually ship web apps that are truly compelling. In the “best case” scenario for customers and developers, I think a ruling that includes forces Apple to change some of their rules to allow 3rd party browsers could change things greatly. Add to that some of the suggestions I made a while back, and I think a lot of this would go away. A “worst case” scenario is a confusing hellscape of competing app stores, browser ballots and even possibly no default apps on first load. Lets hope cooler heads prevail.
