Earlier this month I ran into this article on Twitter, which details inconsistencies and bugs in mobile Safari's version of service workers.
I’m sorry to confirm that most problems are the same that I stated 18 months ago...
This article also talks about Apple's decision to remove service workers after "a period of a few weeks". This is inconsistent with every other browser on the market.
For those that are not web developers, let's dive into what service workers are, and why this is relevant. Service workers are background processes that can be "installed" by websites. They're really neat, and can do many things including:
- Offloading of processing
- Pre-fetching of resources
- Operate your website while you're offline
- Background updates
Service workers are a key component of what Google labels Progressive Web Applications (PWAs). Progressive Web Apps enable you to install the website (or web application) onto your home screen. Once it's installed, service workers can enable it to be run when your phone is offline. When your phone is back online, it can then synchronize and reconcile any data input or updates — unless the service worker has been removed by Apple.
It sounds like a native app. But the difference is 1) It doesn't require you to download it from an App Store, and 2) It's built off of web technologies.
These two reasons means that 1) Apple doesn't get its standard 30% 15% cut of any revenue, and 2) Apple doesn't get to keep control of what does or does not get available to install.
In 2017 alone, Apple made 11 Billion dollars off of the App Store!
But I'll just use another browser.
But doesn't Google have the same incentive?
Google is an interesting case, because yes it has incentive to keep apps in its Google Play store. But the difference is that Google draws the majority of its revenue from its advertising sales: AdSense and AdWords (Over $96B). And advertising sales is more profitable when there are more things to advertise (for example web applications).
This is the main reason why Google makes Chrome. Its using Chromium to help drive web technologies forward (and it's working). Google needs the web to remain open in order for its primary revenue stream to remain profitable.
Apple wants a walled garden
Apple wants you in a walled garden. It wants you to use its App Store to find applications (and tack on an extra 15% fee). It then wants you to use these apps to download news (see Apple instant articles).
It wants the web to remain unstable, slow, and not as useful as native apps. And to do this it only allows you to use one defacto browser that remains extremely buggy.
Hey you! Leave a comment!
Seriously... I really like it when people let me know their thoughts and that they've read this.
