Even the the example at svader.vercel.app/hello-world/webgl/? Testing on the Safari browsers is currently a TODO, and the library is in general still experimental when it comes to wider browser support, but I would have expected at least the standard WebGL examples to work. Does it at least display the "WebGL not supported" message?

WebGL works very well on iOS.

If in doubt try https://luduxia.com/whichwayround/ ;P

Just a white page.

Strange. I'll have to look into this.

Thanks for letting me know!

If you don’t have access to Apple devices, I find Epiphany/GNOME Web to be a pretty good proxy—it uses WebKit, unlike most things these days that use Blink. Most times, Safari issues appear in Epiphany as well. This seems to hit a TypeError in https://svader.vercel.app/_app/immutable/chunks/entry.B0k4a9... line 1, column 9932 (Xe(ht,e)), and I have no time to investigate further.

How good are the developer tools in Epiphany browser?

(I would try but I killed my laptop recently!)

They're identical to Safari, macOS theme and all.

Same here. All examples are white or black pages. All are empty except the slider, which has a non-interactive text that says ”Slide me”. iPhone 15 Pro, iOS 18.1.1.

I strangely can’t get any of the examples to work on iOS - even on chrome.

Chrome on iOS also uses WebKit as backend, as iOS restrictions don’t allow other engines. Same goes for Firefox, Brave, etc…

Edit: Actually not fully true anymore, as of iOS 17.4, you _could_ bring your own engine (https://developer.apple.com/support/alternative-browser-engi...) - with restrictions, of course.
