Xcodebuild: error: SDK "/Applications/Xcode.app/Contents/Developer/Platforms/atform/Developer/SDKs/MacOSX12.3.sdk" cannot be located. The error I was seeing relating to the git binary was: 16:33:18.828 xcodebuild Writing error result bundle to /var/folders/mc/tm26v4sd0pv1hncprqdff72h0000gn/T/ResultBundle_16-33-0018.xcresult

Which copies the older "MacOSX12" SDK into the Xcode 14 folders and seems to make everyone happy. Tl dr the solution is to run sudo cp -R /Library/Developer/CommandLineTools/SDKs/MacOSX12* /Applications/Xcode.app/Contents/Developer/Platforms/atform/Developer/SDKs/

I had this same problem, but none of the solutions above worked for me. Keep in mind that the Xcode tools when opening Xcode after further updates will need to be updated, but in my experience this should NOT affect the CLI tools. It seems the issue is not related to the architecture of the mac (M1 or Intel) or the Xcode version! Keep in mind, tools for the platforms you chose will be downloaded in the background, which might take a bit.

This issue happened on my MacBook Air M1 machine after update macOS Monterey 12.6 released recently and installing Xcode CLI tools version 14.0.
