[Caniuse](https://caniuse.com/mdn-api_intersectionobserver) shows that IntersectionObserver API was added to iOS 12.2 in March 2019.

If those were tested on iOS too, then it also proves it should work - all browsers on iOS use WebKit under the hood.

@MarcP, have you, by any chance, disabled IntersectionObserver in `Settings > Safari > Advanced > Experimental Features`? It should be enabled by default. (see [Safari Technology Preview Release 71 notes](https://developer.apple.com/safari/technology-preview/release-notes/#r71))
