A lthough Apple’s use of skeuomorphism — making computer things look like real things — peaked in the 2000s, it was there from the first GUIs. The trash can is skeuomorphic, as are folders and Stickies. But where macOS flirted with skeuomorphism, the iPhone was up the skeuomorphic tree k-i-s-s-i-n-g.
There was a good reason for that. Steve Jobs wanted the iPhone to be friendly and familiar. A button would quite obviously be a button; a switch would quite obviously be a switch.
