> Apple famously doesn't do any of this with your iPhone You're arguing in favor of a product tour. iOS usability is garbage. There are no affordances. Nothing is discoverable. There are a million inputs (mostly gestures) that no one ever finds out about unless someone tells them or they Google it, and they're not consistent across apps, even first-party apps. Sometimes "swipe the row left" means "remove," sometimes…
>> iOS usability is garbage Yes, that must be why my technologically illiterate 90-year-old grandpa was able to figure out how to use an iPhone after being shown a single swipe gesture.
Please try to keep in mind there is a wide breadth of technical prowess, thought patterns, and comprehension out there. What works great for some people doesn't for others. Also something to keep it mind being able to "figure something out" or "use it" doesn't necessarily make it a good experience, or an ideal one.
