PWAs traditionally have had hardware access not available to web pages within the browser. This makes a PWA more of a security risk than a web page, but also means you can have a PWA compass, or a PWA wifi troubleshooting app, or a PWA government ID app that can use the camera and microphone to validate the user outside Apple’s own APIs. It’s more than just extra cookie storage and expanded localstorage.
So if a PWA was deployed via Chrome, Apple would also have to give the Chrome PWA instance those permissions, without Apple being able to have intimate knowledge of the consequences on the back end, since Chrome isn’t WebKit. And Apple doesn’t have the same level of security vetting for third party software (like Chrome) that they do for OS internals (like WebKit).
If this doesn’t represent what you had in mind, could you quote specific comments?
I would disagree with the premise. A website and an application aren’t the same thing just because they are written in the same language (javascript).
This isn’t what I claimed. You are correct that using the same programming language doesn’t mean two things are in the same category, but that’s not my point. They are using the same:
Programming language
Runtime environment
Layout engine
Style & formatting engine
Markup language
Style language
Browser APIs
The only difference is that a few additional APIs are available and some browser restrictions have different value. That’s because Progressive Web Apps are literally meant to be websites that provide functionality and have progressive enhancements (i.e. feature detection, you use what you can without breaking because of what you can’t). This means we’re talking about the PWA being the same website, displayed in the same application, served from the same server.
Many, if not most, PWAs are websites that provide the same actual functionality with or without being installed, maybe without a couple niceties (e.g. bigger offline storage). Many don’t use features beyond what they offer as a normal website. This means all there is to distinguish PWAs and websites is how the user opened them on their phone.
I would disagree with the premise. A website and an application aren’t the same thing just because they are written in the same language (javascript). PWAs are apps in every sense of the word. Websites are not. I think the comments section on this Ars techinca article cover it pretty well, rather than re-hashing the same. https://arstechnica.com/gadgets/2024/03/apple-changes-course-will-keep-iphone-eu-web-apps-how-they-are-in-ios-17-4/?comments=1&comments-page=2
