Apple has published a PWA😎
Wait What?😱
There is a new bug report app, built with create-react-app. Apple, as many other React devs, kept the default manifest unchanged. So it's a PWA with no iOS icon (React icon on other platforms) and React title 🤦♂️

👿Evil Apple is back, and it's killing PWAs on iOS for EU users🇪🇺
"To comply with the DMA’s requirements, we had to remove the Home Screen web apps feature in the EU.

－"Minimal impact to their functionality"

When you request for push notification permission when the page loads,

We can confirm that PWAs on iOS 17.4 are turned off for EU users on b3, while Apple keeps silent about it as if it's not happening.
At this point, it’s a feature disabled on purpose, and they want to keep it that way for the stable version to ship in a few weeks to all users.
iOS 17.4 beta 3 is out, release notes don't mention anything regarding web apps in EU, and also Safari release notes are still not updated.
Looking forward for EU users testing if PWA support is back or still gone.

We've asked Apple to implement Web Push in iOS for too many years. The answer was always the same: null, sarcastic, or accuser.
We are all happy that you finally changed your mind and did it (partially) but don't sell it as if you always supported it or as if it was your idea.

The classic lazy way from Apple.
They are breaking the web because they don't want to. "Too much engineering work" says the trillion-dollar company.
Under the DMA, Apple's not allowed to retain the home screen web app feature, powered by WebKit, unless it did the engineering work to enable other browser engines to do the same ... so instead nobody can do it!

⛔️ Important Information for iOS Users Regarding PWA support removal in the EU.
Below are some ideas and potential problems we might face if these changes make their way into the final version. 👇
I updated my iPhone to iOS 17.4 beta 2 and PWAs now only open as a web page.
That means push notifications are gone but at least the service worker still seems intact as the PWA still works offline.

If you have a web app and customers from EU, consider completing this survey to help in the Apple decision to remove PWA support on iOS👇
We need immediate support from web developers and businesses that operate online in the EU. The European Commission needs to hear from YOU to understand the devastating impact Apple’s new ban will have on your livelihoods, businesses and customers.
