Apple broke web apps in iOS 17 beta and hasn't fixed them
(www.theregister.com)
This is a most excellent place for technology news and articles.
Would it work if the underlying OS doesn't support web apps?
I believe web apps are essentially just a full screen safari window. If “web content in a native app” isn’t working, a very large number of apps would be dead in the water and I doubt it would be released, even as a beta.
But I could of course be wrong.
But as far as I can tell, that is exactly what the article implies. And AFAIK, Voyager is the only web app I use currently.
No, a web app, otherwise known as a Progressive Web App or PWA, are just shortcuts on your home screen that open a fullscreen instance of Safari to the originally provided URL. The article explicitly talks about apps that don’t follow Apple guidelines, which means they wouldn’t be able to get a TestFlight, nor into the App Store.
