I'm probably late to the party, but one of my favorite iOS 27 features that people don't seem to be talking about is the ability to ask Siri to perform an action on the current page. Saying things like "enter my email address in the text field", or "draft a reply to this message with availability based on my Calendar" have been saving me a lot more time than I thought they would. It's also great for inaccessible applications when Voiceover can't find or won't click buttons.
