Apple Confirms iOS 17.4 Removes Home Screen Web Apps In the EU (9to5mac.com) 136

Apple has now offered an explanation for why iOS 17.4 removes support for Home Screen web apps in the European Union. Spoiler: it's because of the Digital Markets Act that went into effect last August. 9to5Mac reports: Last week, iPhone users in the European Union noticed that they were no longer able to install and run web apps on their iPhone's Home Screen in iOS 17.4. Apple has added a number of features over the years to improve support for progressive web apps on iPhone. For example, iOS 16.4 allowed PWAs to deliver push notifications with icon badges. One change in iOS 17.4 is that the iPhone now supports alternative browser engines in the EU. This allows companies to build browsers that don't use Apple's WebKit engine for the first time. Apple says that this change, required by the Digital Markets Act, is why it has been forced to remove Home Screen web apps support in the European Union.

Apple explains that it would have to build an "entirely new integration architecture that does not currently exist in iOS" to address the "complex security and privacy concerns associated with web apps using alternative browser engines." This work "was not practical to undertake given the other demands of the DMA and the very low user adoption of Home Screen web apps," Apple explains. "And so, to comply with the DMA's requirements, we had to remove the Home Screen web apps feature in the EU." "EU users will be able to continue accessing websites directly from their Home Screen through a bookmark with minimal impact to their functionality," Apple continues.

It's understandable that Apple wouldn't offer support for Home Screen web apps for third-party browsers. But why did it also remove support for Home Screen web apps for Safari? Unfortunately, that's another side effect of the Digital Markets Act. The DMA requires that all browsers have equality, meaning that Apple can't favor Safari and WebKit over third-party browser engines. Therefore, because it can't offer Home Screen web apps support for third-party browsers, it also can't offer support via Safari. [...] iOS 17.4 is currently available to developers and public beta testers, and is slated for a release in early March.
The full explanation was published on Apple's developer website today.

      Home screen apps are not like web pages. They're a full-screen experience with no window chrome. Yes, this change breaks things quite badly. And Apple knows this. They also know that once third-party browsers get a foothold, people will want to have web apps running in other browsers, because Safari just isn't nearly good enough, and they aren't willing to spend the money to build a better browser that can actually compete in a free market. So instead, they're taking away features from EU users so that other browser vendors won't be able to compete as visibly.

      And no, it does not make sense. This was a simple problem that had a simple solution — creating APIs to allow apps to register a home screen item that calls openURL with a specific app-defined URL scheme to launch that app. It would have taken all of one hour for an engineer to implement this, max. But instead of implementing that solution, Apple decided to abuse European users for daring to demand the right to run the browser of their choice by taking away functionality that some of them depend on, and using the DMA as a pathetic excuse.

      They're hiding behind "security", throwing shade at other browsers, and making ludicrous claims about one web app stealing data from another web app that are not based on anything other than hypothetical designs of hypothetical browsers that do not even exist yet. In reality, absolutely nothing prevents any other browser vendor from creating an entirely isolated cookie and data storage environment for each web app, and whether or not they do so has no bearing whatsoever on whether Apple should allow those apps to create full-screen web apps. After all, the security of third-party apps is not Apple's problem.

      No, this is just one more bullshit abuse by Apple, attempting to control what users do on devices that they own, and their decision flies flagrantly in the face of the rules that the EU is imposing on them.

      This is inexcusably childish behavior by Apple, and it is in the best interests of everyone, whether in the EU or not, for the EU to bury Apple under a mountain of sanctions so big that their stock price drops ten bucks on the first day. It's the only thing companies like that understand.

        EU officials have already signalled that this illegal behavior will not be tolerated. Apple is subject to the law, just like any other enterprise. I predict this will get very expensive for them. EU rules can result in a fine of up to 5% of annual turnover. A prohibition to sell the affected devices can then be the next step.

      You can still launch a web page from a home page. That's what the summary is talking about with 'bookmarks.'

      What you can't do is launch a special webapp that looks like a regular app, i.e. full screen with no browser stuff around it. I expect Apple doesn't even use Safari proper for that, but rather has a little app that just consists of a full screen webkit component. But that is arguably "a browser" and it certainly is treated differently than any random browser you might install.

          No. That's the newspaper article summary. The issue is webkit.

          Safari itself is an app with a webkit view and a few ancillary controls like an address bar and back/forward buttons. You have long been welcome to make your own browser on iOS, provided it was likewise a webkit view. In fact, millions of people have the Google Chrome app installed.

          You couldn't use something other than webkit though. Even Google has to use Apple's webkit, not their own.

      Seems to me like that all makes sense.

      Except of course, it's obvious bullshit. The reason for disabling web apps is because the Safari engine goes out of its way to cripple the usefulness of web apps. If you could switch to Chrome or potentially another engine, that engine could easily make native OS features available to web apps, making web apps as powerful as native ones. A user could then install a web app icon on the home screen, and you'd have a system as easy to use as the App Store, but completely outside of it.

        Indeed not worth the money or how they put it : Addressing the complex security and privacy concerns associated with web apps using alternative browser engines would require building an entirely new integration

    • The full explanation given by Apple below, missing from the article's summary. In short: The system that today guarantees isolated security and privacy for each web application is built into WebKit, not the core of iOS, and alternative browsers could theoretically implement a not-good-enough replacement that would lead to security issues.. Apple cannot or will not verify this in other browsers, and does not want to build an entirely new security architecture in iOS. However, it still wants to ensure the security and confidentiality of all apps. That's why it's removing this feature.

      Perfect!

      Logical, and exactly what I have been saying for years as to why third-party Rendering Engines are disallowed on Apple OSes other than the admittedly somewhat less-secure (but not at all restrictive) macOS.

  • What is the practical impact on regular browser users, if anything? I don't use armor care about PWAs. Does this mean I have to move to Europe to avoid all those stupid "ADD THIS PAGE TO YOUR HOME SCREEN!!!!!11111oneoneelecencos(0)" banners half the sites I visit?
  • Apple are doing this to try to get users up in arms so that they protest the EU Commission/Parliament and get the laws changed. However what they fail to realise is that the EU is not the USA. Unlike the USA where a large number of the citizens could tell you who their senator was most people in the EU whilst they could tell you who their local, regional and national politicians are couldn't tell you who their MEP is. In the EU people don't have the mistrust of government like they do in the USA. Therefore

To stay youthful, stay useful.
