iOS and Safari is riddled with WebRTC bugs like this. Sounds similar to my experience. Everything consistently works great in Chrome and Firefox and then only kinda works Safari. worst browser on the planet
I've jokingly referred to Safari as SafarIE for the last 5 years. It does tick all these boxes:
1. Backed by an OS manufacturer that doesn't care about the web
2. Spends more time working on features that suit itself than meeting standards agreed upon by a body of which they're a part.
3. The only sanctioned/allowed browser on their platform (MS didn't even achieve this holy grail)
4. Lagging behind most other popular browsers by years in some cases
But due to it being the ONLY browser that'll run on iOS, I have no choice but to dumb down user experience for it. This year's lovely issue has been MediaRecorder - but supposedly that's made it into the most recent release.
I use firefox on iOS, it’s even set as my default browser. Curious what you mean by “safari is the only browser that works in iOS”? For in browser video chat? Genuinely curious, what are the limitations?
Ah I see, thanks I had no idea (I assume most average users are in the same situation). I assume IpadOS is the same, and only MacOS allows a true non safari browser.
iOS binaries that are not signed by apple are not permitted to mark memory pages as executable if they have previously been writable.
This restriction makes exploiting buffer overruns very difficult on iOS - particularly important as objective-c doesn't give you much help avoiding them.
However, you can't write a runtime compiler unless you can generate bytecode (write) and then execute it, and nobody has found a way to write a performant javascript or CSS engine without some form of runtime compilation.
So, Apple does allow you to write your own browser backends, but they won't give their signature, which would permit you to use riskier techniques to gain performance.
In practice, that means any browser not using the safari engines would be unacceptably slow on the modern web.
