I’ve mentioned before that I don’t enable notifications on my phone. Text messages are the only exception. I don’t want to get notified if a new email arrives (I avoid email on my phone completely) and I certainly don’t want some social media app telling me somebody liked or faved something.

But the number one feature I’d like to see in Safari on iOS is web notifications.

It’s not for me personally, see. It’s because it’s the number one reason why people are choosing not to go all in progressive web apps.

Safari on iOS is the last holdout. But that equates to enough marketshare that many companies feel they can’t treat notifications as a progressive enhancement. While I may not agree with that decision myself, I get it.

When I’m evangelising the benefits of building on the open web instead of making separate iOS and Android apps, I inevitably get asked about notifications. As long as mobile Safari doesn’t support them—even though desktop Safari does—I’m somewhat stumped. There’s no polyfill for this feature other than building an entire native app, which is a bit extreme as polyfills go.

And of course, unlike on your Mac, you don’t have the option of using a different browser on your iPhone. As long as mobile Safari doesn’t support web notifications, nothing on iOS can support web notifications.

I’ve got progressive web apps on the home screen of my phone that match their native equivalents feature-for-feature. Twitter. Instagram. They’re really good. In some ways they’re superior to the native apps; the Twitter website is much calmer, and the Instagram website has no advertising. But if I wanted to get notifications from any of those sites, I’d have to keep the native apps installed just for that one feature.

So in the spirit of complaining about web browsers in a productive way, I just want to throw this plea out there: Apple, please support web notifications in mobile Safari!

The good news is that web notifications on iOS might be on their way. Huzzah!

Alas, we’re reliant on Maximiliano’s detective work to even get a glimpse of a future feature like this. Apple has no public roadmap for Safari. There’s this status page on the Webkit blog but it’s incomplete—web notifications don’t appear at all. In any case, WebKit and Safari aren’t the same thing. The only way of knowing if a feature might be implemented in Safari is if it shows up in Safari Technology Preview, at which point it’s already pretty far along.

So while my number one feature request for mobile Safari is web notifications, a close second would be a public roadmap.

It only seems fair. If Apple devrels are asking us developers what features we’d like to see implemented—as they should!—then shouldn’t those same developers also be treated with enough respect to share a roadmap with them? There’s not much point in us asking for features if, unbeknownst to us, that feature is already being worked on.

But, like I said, my number one request remains: web notifications on iOS …please!

Dave recently wrote some good advice about what to do—and what not to do—when it comes to complaining about web browsers. I wrote something on this topic a little while back:

If there’s something about a web browser that you’re not happy with (or, indeed, if there’s something you’re really happy with), take the time to write it down and publish it

To summarise Dave’s advice, avoid conspiracy theories and snark; stick to specifics instead.

It’s very good advice that I should heed (especially the bit about avoiding snark). In that spirit, I’d like to document what I think is a bug on iOS.

I don’t need to name the specific browser, because there is basically only one browser allowed on iOS. That’s not snark; that’s a statement of fact.

This bug involves navigating from a progressive web app that has been installed on your home screen to an external web view.

To illustrate the bug, I’ll use the example of The Session. If you want to recreate the bug, you’ll need to have an account on The Session. Let me know if you want to set up a temporary account—I can take care of deleting it afterwards.

Here are the steps:

1. Navigate to thesession.org in Safari on an iOS device.
2. Add the site to your home screen.
3. Open the installed site from your home screen—it will launch in standalone mode.
4. Log in with your username and password.
5. Using the site menu, navigate to the links section of the site.
6. Click on any external link.
7. After the external link opens in a web view, tap on “Done” to close the web view.

Expected behaviour: you are returned to the page you were on with no change of state.

Actual behaviour: you are returned to the page you were on but you are logged out.

So the act of visiting an external link in a web view while in a progressive web app in standalone mode seems to cause a loss of cookie-based authentication.

This isn’t permanent. Clicking on any internal link restores the logged-in state.

It is surprising though. My mental model for opening an external link in a web view is that it sits “above” the progressive web app, which remains in stasis “behind” it. But the page must actually be reloading, either when the web view is opened or when the web view is closed. And that reload is behaving like a fetch event without credentials.

Anyway, that’s my bug report. It may already be listed somewhere on the WebKit Bugzilla but I lack the deductive skills to find it. I’m not even sure if that’s the right place for this kind of bug. It might be specific to the operating system rather than the rendering engine.

This isn’t a high priority bug, but it is one of those cumulatively annoying software paper cuts.

Hope this helps!

I was moaning about Safari recently. Specifically I was moaning about the ridiculous way that browser updates are tied to operating system updates.

But I felt bad bashing Safari. It felt like a pile-on. That’s because a lot of people have been venting their frustrations with Safari recently:

• Jorge Arango wrote Back to the Bad Old Days of the Web,
• Dave Rupert wrote One-offs and low-expectations with Safari,
• Perry Sun wrote For developers, Apple’s Safari is crap and outdated, and
• Tim Perry wrote Safari isn’t protecting the web, it’s killing it.

I think it’s good that people share their frustrations with browsers openly, although I agree with Baldur Bjarnason that’s good to avoid Kremlinology and the motivational fallacy when blogging about Apple.

It’s also not helpful to make claims like “Safari is the new Internet Explorer!” Unless, that is, you can back up the claim.

On a recent episode of the HTTP 203 podcast, Jake and Surma set out to test the claim that Safari is the new IE. They did it by examining Safari according to a number of different measurements and comparing it to the olden days of Internet Explorer. The result is a really fascinating trip down memory lane along with a very nuanced and even-handed critique of Safari.

And the verdict? Well, you’ll just to have to listen to the podcast episode.

If you’d rather read the transcript, tough luck. That’s a real shame because, like I said, it’s an excellent and measured assessment. I’d love to add it to the links section of my site, but I can’t do that in good conscience while it’s inaccessible to the Deaf community.

When I started the Clearleft podcast, it was a no-brainer to have transcripts of every episode. Not only does it make the content more widely available, but it also makes it easier for people to copy and paste choice quotes.

Still, I get it. A small plucky little operation like Google isn’t going to have the deep pockets of a massive corporation like Clearleft. But if Jake and Surma were to open up a tip jar, I’d throw some money in to get HTTP 203 transcribed (I recommend getting Tina Pham to do it—she’s great!).

I apologise for my note of sarcasm there. But I share because I care. It really is an excellent discussion; one that everyone should be able to access.

Update: the bug with that episode of the HTTP 203 podcast has been fixed. Here’s the transcript! And all future episodes will have transcripts too:

Some folks called us out for lacking transcripts for our podcasts. Fair point! So, here we go (and all future episodes will have transcripts)https://t.co/HmfwBvAicA

Safari has been subjected to a lot of ire recently. Most of that ire has been aimed at the proposed changes to the navigation bar in Safari on iOS—moving it from a fixed top position to a floaty bottom position right over the content you’re trying to interact with.

Courage.

It remains to be seen whether this change will actually ship. That’s why it’s in beta—to gather all the web’s hot takes first.

But while this very visible change is dominating the discussion, invisible changes can be even more important. Or in the case of Safari, the lack of changes.

Compared to other browsers, Safari lags far behind when it comes to shipping features. I’m not necessarily talking about cutting-edge features either. These are often standards that have been out for years. This creates a gap—albeit an invisible one—between Safari and other browsers.

Jorge Arango has noticed this gap:

I use Safari as my primary browser on all my devices. I like how Safari integrates with the rest of the OS, its speed, and privacy features. But, alas, I increasingly have issues rendering websites and applications on Safari.

That’s the perspective of an end-user. Developers who have to deal with the gap in features are more, um, strident in their opinions. Perry Sun wrote For developers, Apple’s Safari is crap and outdated:

Don’t get me wrong, Safari is very good web browser, delivering fast performance and solid privacy features.

But at the same time, the lack of support for key web technologies and APIs has been both perplexing and annoying at the same time.

Alas, that post also indulges in speculation about Apple’s motives which always feels a bit too much like a conspiracy theory to me. Baldur Bjarnason has more to say on that topic in his post Kremlinology and the motivational fallacy when blogging about Apple. He also points to a good example of critiquing Safari without speculating about motives: Dave’s post One-offs and low-expectations with Safari, which documents all the annoying paper cuts inflicted by Safari’s “quirks.”

Another deep dive that avoids speculating about motives comes from Tim Perry: Safari isn’t protecting the web, it’s killing it. I don’t agree with everything in it. I think that Apple—and Mozilla’s—objections to some device APIs are informed by a real concern about privacy and security. But I agree with his point that it’s not enough to just object; you’ve got to offer an alternative vision too.

That same post has a litany of uncontroversial features that shipped in Safari looong after they shipped in other browsers:

Again: these are not contentious features shipping by only Chrome, they’re features with wide support and no clear objections, but Safari is still not shipping them until years later. They’re also not shiny irrelevant features that “bloat the web” in any sense: each example I’ve included above primarily improving core webpage UX and performance. Safari is slowing that down progress here.

But perhaps most damning of all is how Safari deals with bugs.

A recent release of Safari shipped with a really bad Local Storage bug. The bug was fixed within a day. Yay! But the fix won’t ship until …who knows?

This is because browser updates are tied to operating system updates. Yes, this is just like the 90s when Microsoft claimed that Internet Explorer was intrinsically linked to Windows (a tactic that didn’t work out too well for them in the subsequent court case).

I don’t get it. I’m pretty sure that other Apple products ship updates and fixes independentally of OS releases. I’m sure I’ve received software updates for Keynote, Garage Band, and other pieces of software made by Apple.

And yet, of all the applications that need a speedy update cycle—a user agent for the World Wide Web—Apple’s version is needlessly delayed by the release cycle of the entire operating system.

I don’t want to speculate on why this might be. I don’t know the technical details. But I suspect that the root cause might not be technical in nature. Apple have always tied their browser updates to OS releases. If Google’s cardinal sin is avoiding anything “Not Invented Here”, Apple’s downfall is “We’ve always done it this way.”

Evergreen browsers update in the background, usually at regular intervals. Firefox is an evergreen browser. Chrome is an evergreen browser. Edge is an evergreen browser.

Safari is not an evergreen browser.

That’s frustrating when it comes to new features. It’s unforgivable when it comes to bugs.

At least on Apple’s desktop computers, users have the choice to switch to a different browser. But on Apple’s mobile devices, users have no choice but to use Safari’s rendering engine, bugs and all.

As I wrote when I had to deal with one of Safari’s bugs:

I wish that Apple would allow other rendering engines to be installed on iOS devices. But if that’s a hell-freezing-over prospect, I wish that Safari updates weren’t tied to operating system updates.
