Would suggest to @Mathew potentially might be a good idea to rethink the bottom bar for options
Doesn’t work very well on iOS 15 due to the new positioning of the menu and how it comes up and there’s a lot of auto adjustment of the bar there that feels very clunky
Would you be able to post a screenshot of what this looks like please?
One of my own personal web projects involved a lot of experimental approaches to navigation designed around the mobile’s Goldilocks zone for thumbs. Illustrated here by Lux Optics as the reachable plains.
From your description, it’s possible the safari changes will interfere with the approach I went with. Will need to test it when I get the previews, but annoying if the new interface obstructs objects now rather than pushing them out of the way.
That could just be a bug. I imagine this should come across as nothing more than a UI update to the perspective of the web developer. the way the browser functions should remain the same, so web apps should continue to respond accordingly once bugs are ironed out. So no changes should be necessary for your web app to continue to function correctly.
If you’re using fixed elements, I suspect the safari transitions will result in some janky changes to your page layout, but nothing major. You can correct for those things though, so the adjustments are fluid transitions.
