After watching the WWDC 2023 “What’s new in web apps” session, I am unclear on current best practice for custom icons and custom splash screens in iOS PWAs (progressive web apps). Should we now use manifest.json entries, or the old link/meta tags way still?
Is there any Apple sample code for a PWA that, when added to the Home Screen on iOS, shows an app with custom icon and a custom splash screen compatible with all devices? The Configuring Web Applications documentation is marked as Archived. Is there a newer version?
Specifically, do we still have to provide a splash screen PNG for every possible device resolution? This is a serious burden and likely to break whenever a new device is released. It would be ideal if a splash screen could be synthesized by centering an icon on a background of a given color. I can’t get that to work.
