It's not easy, though. Most of my day job is spent trying to get html interactives on an e-learning platform to work reliably with iOS's ridiculous nonstandard interaction rules around when media is allowed to play. It's worse than working with the 20 year old jsp+servlet system that serves the interactives and business logic. no other browser behaves like iOS safari and to debug and develop against it you need an ios and macos device sitting on your desk. Firefox and Firefox on Android are a breeze but a rounding-error in our usage metrics, even accounting for our development. Apple desparately hobbles the web platform to collect IAP taxes.
