@saschwarz are you referring to multi-touch interactions as supported on a Macintosh laptops and/or Magic Trackpad? I don't believe that those use the same APIs for the touchscreen touch that that sample is showcasing. I'm investigating both touchscreen touch and Apple trackpad touch gestures in our app too. The same might be true of your comment @eyaler, it sounds like you're talking about a trackpad as well.
I found this helpful article that explains that those events are generally mapped to
mouseWheelevents in browsers, and that there hasn't been a great consensus formed with how to handle them, but the crux is they don't emittouch*events that are used in these examples.pepelsbey commentedon Jan 16, 2026
Both demos work for me in Safari on iOS 26.2
It needs a deeper investigation and cross-browser/platform testing.
