If your home has a device that supports AirPlay, such as Apple TV or an AirPlay-compatible TV, you will find it very easy to use "AirPlay" to screen the iPhone. However, the iPhone cannot directly cast the screen to the Mac screen through airplay. Although there are many wired screen projection solutions, they are not as convenient as wireless.
However, we can make Mac "support" aircasting by installing Mac software.
AirServer for Mac (Mobile phone projection Mac artifact)
AirServer
AirServer is the one with the best support here. After installing and opening it on a Mac, open the control center of the iPhone or iPad and select "Screen Mirroring" to see the "AirPlay" device named by the Mac. Tap it to display the iPhone or iPad screen on the Mac screen. Screen projection resolution and delay can meet general presentation scenarios.
AirServer also supports simultaneous projection and display of multiple iOS devices. I tried to cast two iPhones and one iPad Pro to the Mac at the same time.
Mukai
ScreenShare is a domestic free Mac screen projection software that not only supports iPhone and iPad screen projection to computers, but also screen sharing between computers.
Muxiang also has a graffiti marking function that the first two do not have, which is very suitable for conference presentations. Mianxiang also has a TV version, which allows TVs that are not compatible with AirPlay to use AirPlay.
But the screen sharing screen resolution will be worse than the former. And when I use it, there are still some bugs when opening photos/videos on the iPhone. Fortunately, the software is free, so I recommend it.
