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.
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?
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.
