From what I heard Lightning didn't have the bandwidth to properly support USB3 so they had to do some kind of hacky workaround with the pins. They tried it one year on the iPad Pro then ditched it for USB-C on the next one and never brought it to the iPhone.Right. Same for the Lightning-port iPad Pros, which also supported USB3 (even though nobody talks about it when trying to justify the "need" to switch to USB-C).
