How to connect iPad/iPhone to Macbook without cable?

Question

iPhone

When googling, it gives out some kind of nonsense, where you still need to use a USB cable.
If apples are aiming for a wireless existence, why isn't there a simple, intuitive way, such as via BT

Answer 1

Connect the device once with a cable, then in iTunes go to the device and check the box "Sync over WiFi"

Answer 2

AirDrop
Handoff
iCloud
in such a bundle is quite convenient, of course, depending on what you specifically want

Answer 3

There is an easy way - WiFi, but iTunes itself is far from an intuitive application;)
