Talking with apple support was extremely disappointing.
Look at this statement on this link:
https://support.apple.com/guide/mac-help/wi-fi-syncing-mchlada1d602/mac
Before disconnecting your device from your Mac, click the Eject button in the Finder sidebar. The device icon disappears, but Wi-Fi syncing remains turned on. The icon reappears automatically the next time your Mac and device are connected to the same WI-Fi network.
The second sentence says I should see my iPhone on the Mac Finder automatically when both devices are on the same Wi-Fi. AND WITHOUT ANY USB CABLE.....
I also have had this experience one month ago that I could sync my iPhone with my Mac Book wirelessly and transfer some files to my iPhone without any cable and just through Wi-Fi. I do not know what is wrong at the moment but after "2 hours talking with 4 people from apple support the problem is still going on and they couldn't solve it! It's pity and very disappointing.
I showed all of them this sentence on the above-mentioned link. To me, it was like they even don't know this!!!
It's a serious problem and I recommend apple company to think about the support team to put some experts to avoid wasting customers' time!!
Enough funny that one of them told me it's not necessary to see the iPhone's icon on the Mac when the USB cable is not connected. COME ON! If all the time iPhone needs to be connected to Mac by a USB cable what's the point of synchronizing wirelessly?!!!!! GUYS, IT SHOULD BE A CONNECTION BY WI-FI WITHOUT CABLE.... :))))))
