I feel for BaseCamp, I do. But give up on the native app path. Make sure your existing web interface is a good progressive web app and you can end-run around Apple.

Apple’s attack on service workers
Apple aren’t the best at developer relations. But, bad as their communications can be, I’m willing to cut them some slack. After all, they’re not used to talking with the developer community.
John Wilander wrote a blog post that starts with some excellent news: Full Third-Party Cookie Blocking and More. Safari is catching up to Firefox and disabling third-party cookies by default. Wonderful! I’ve had third-party cookies disabled for a few years now, and while something occassionally breaks, it’s honestly a pretty great experience all around. Denying companies the ability to track users across sites is A Good Thing.
In the same blog post, John said that client-side cookies will be capped to a seven-day lifespan, as previously announced. Just to be clear, this only applies to client-side cookies. If you’re setting a cookie on the server, using PHP or some other server-side language, it won’t be affected. So persistent logins are still doable.
Then, in an audacious example of burying the lede, towards the end of the blog post, John announces that a whole bunch of other client-side storage technologies will also be capped to seven days. Most of the technologies are APIs that, like cookies, can be used to store data: Indexed DB, Local Storage, and Session Storage (though there’s no mention of the Cache API). At the bottom of the list is this:
Service Worker registrations
Okay, let’s clear up a few things here (because they have been so poorly communicated in the blog post)…
The seven day timer refers to seven days of Safari usage, not seven calendar days (although, given how often most people use their phones, the two are probably interchangable). So if someone returns to your site within a seven day period of using Safari, the timer resets to zero, and your service worker gets a stay of execution. Lucky you.
This only applies to Safari. So if your site has been added to the home screen and your web app manifest has a value for the “display” property like “standalone” or “full screen”, the seven day timer doesn’t apply.
That piece of information was missing from the initial blog post. Since the blog post was updated to include this clarification, some people have taken this to mean that progressive web apps aren’t affected by the upcoming change. Not true. Only progressive web apps that have been added to the home screen (and that have an appropriate “display” value) will be spared. That’s a vanishingly small percentage of progressive web apps, especially on iOS. To add a site to the home screen on iOS, you need to dig and scroll through the share menu to find the right option. And you need to do this unprompted. There is no ambient badging in Safari to indicate that a site is installable. Chrome’s install banner isn’t perfect, but it’s better than nothing.
Just a reminder: a progressive web app is a website that
- runs on HTTPS,
- has a service worker,
- and a web manifest.
Adding to the home screen is something you can do with a progressive web app (or any other website). It is not what defines progressive web apps.
In any case, this move to delete service workers after seven days of using Safari is very odd, and I’m struggling to find the connection to the rest of the blog post, which is about technologies that can store data.
As I understand it, with the crackdown on setting third-party cookies, trackers are moving to first-party technologies. So whereas in the past, a tracking company could tell its customers “Add this
script element to your pages”, now they have to say “Add this
The best explanation I can come up with for this move by Apple is that it feels like the neatest solution. That’s neat as in tidy, not as in nifty. It is definitely not a nifty solution.
If some technologies set by a specific domain are being purged after seven days, then the tidy thing to do is purge all technologies from that domain. Service workers are getting included in that dragnet.
Now, to be fair, browsers and operating systems are free to clean up storage space as they see fit. Caches, Local Storage, Indexed DB—all of those are subject to eventually getting cleaned up.
So I was curious. Wanting to give Apple the benefit of the doubt, I set about trying to find out how long service worker registrations currently last before getting deleted. Maybe this announcement of a seven day time limit would turn out to be not such a big change from current behaviour. Maybe currently service workers last for 90 days, or 60, or just 30.
There was no time limit previously.
This is not a minor change. This is a crippling attack on service workers, a technology specifically designed to improve the user experience for return visits, whether it’s through improved performance or offline access.
I wouldn’t be so stunned had this announcement come with an accompanying feature that would allow Safari users to know when a website is a progressive web app that can be added to the home screen. But Safari continues to ignore the existence of progressive web apps. And now it will actively discourage people from using service workers.
If you’d like to give feedback on this ludicrous development, you can file a bug (down in the cellar in the bottom of a locked filing cabinet stuck in a disused lavatory with a sign on the door saying “Beware of the Leopard”).
No doubt there will still be plenty of Apple apologists telling us why it’s good that Safari has wished service workers into the cornfield. But make no mistake. This is a terrible move by Apple.
I will say this though: given The Situation we’re all living in right now, some good ol’ fashioned Hot Drama by a browser vendor behaving badly feels almost comforting.

Cargo cultism is not a strategy:
Apple and Google get it wrong just as often as the rest of us.

The web is far from perfect, but I think we underrate how resilient it can be.
If you thought maintaining a web project was hard, just wait till you try keeping an app in the app store…
Just before the 2019 holidays, I received an email from Apple notifying me that the app “does not follow one or more of the App Store Review Guidelines.” I signed in to Apple’s Resource Center, where it elaborated that the app had gone too long without an update. There were no greater specifics, no broken rules or deprecated dependencies, they just wanted some sort of update to prove that it was still being maintained or they’d pull the app from the store in December.
Here’s what it took to keep that project up and running…

From Xerox PARC to the World Wide Web:
The internet did not use a visual spatial metaphor. Despite being accessed through and often encompassed by the desktop environment, the internet felt well and truly placeless (or perhaps everywhere). Hyperlinks were wormholes through the spatial metaphor, allowing a user to skip laterally across directories stored on disparate servers, as well as horizontally, deep into a file system without having to access the intermediate steps. Multiple windows could be open to the same website at once, shattering the illusion of a “single file” that functioned as a piece of paper that only one person could hold. The icons that a user could arrange on the desktop didn’t have a parallel in online space at all.

A good overview of the unfair playing field of web browsers, dominated by the monopolistic practices by Google and Apple.
Mozilla is no longer fighting for market share of its browser: it is fighting for the future of the web.

Frank yearns for just-in-time computing:
With each year that goes by, it feels like less and less is happening on the device itself. And the longer our work maintains its current form (writing documents, updating spreadsheets, using web apps, responding to emails, monitoring chat, drawing rectangles), the more unnecessary high-end computing seems. Who needs multiple computers when I only need half of one?

The ellipsis is the new hamburger.
It’s disappointing that Apple, supposedly a leader in interface design, has resorted to such uninspiring, and I’ll dare say, lazy design in its icons. I don’t claim to be a usability expert, but it seems to me that icons should represent a clear intention, followed by a consistent action.

Aaron knows what he’s talking about when it comes to authentication, and Apple’s latest move with sign-in for native apps gets the thumbs up.
Sign In with Apple is a good thing for users! This means apps will no longer be able to force you to log in with your Facebook account to use them.
This does not mean that Apple is requiring every app to use Sign in with Apple.

I also discussed this accessibility events feature with my friend who is a screen reader user herself. She said it feels like it’s a first step towards a well-meant digital apartheid.

Some advice from Andy on creating a dark theme for your website. It’s not just about the colours—there are typography implications too.

This is a terrific spot-on piece by Rachel. I firmly believe that healthy competition and diversity in the browser market is vital for the health of the web (which is why I’m always saddened and frustrated to hear web developers wish for a single monocultural rendering engine).

If you don’t fancy watching this video, Eric Runyon has written down the salient points about what it means for developers now that websites can be viewed on the Apple Watch. Basically, as long as you’re writing good, meaningful markup and you’ve got a sensible font stack, you’re all set.
Or, as Tim puts it:
When we build our sites in a way that allows people using less-capable devices, slower networks and other less than ideal circumstances, we end up better prepared for whatever crazy device or technology comes along next.

The Internet is a place for the people, like parks, libraries, museums, historic places. It’s okay if corporations want to exploit the net, like DisneyLand or cruise lines, but not at the expense of the natural features of the net.
