Just now, having looked Apple's documentation (which I've missed previously):
developer.apple.com
I stand corrected....
Other rendering engines, other than WebKit is coming to iOS 17.4.
Which is excellent news, since iOS users will finally have real options for web browsers.
Current iOS browsers are very much the same, all using WebKit engine, which limits their ability to do a lot of functions.
Here's a great example.
Current AdGuard for iOS (from Apple Store) can only perform both basic and cosmetic filtering.
It cannot do HTML filtering. HTML filtering is where AdGuard will be able to alter HTML code of the page, before it's loaded. This is a more advanced version that allows for complex filtering rules that's currently not possible with current WebKit rendering engine.
So the next questions becomes....Which applications or extensions support HTML filtering using AdGuard products?
In this article, we explain how to write custom filtering rules for use in AdGuard products. To test your rules, you can download the AdGuard app
adguard.com
Currently supported on:
1. adguard for windows (of course, since the desktop OS can do anything)
2. adguard for mac (of course, since the desktop OS can do anything)
3. adguard for android (this is the advantage of android over the ios)
4. adguard browser extension for firefox (this is an advantage that firefox has over other browsers)
The other program that does HTML filtering is uBlock Origin.
The fact that your iPhone will be able to use another rendering engine, allows for adguard (or ublock origin for example), to develop an app for these 3rd party browsers (that will be able to be side-loaded).
That's a huge win for anyone using an iPhone, since this technology is currently not available for iOS (only for Android).
This increases the security and privacy of your web browser for iOS, which is a win for everyone.
