apple shim

[!TIP] shim A.K.A. stub / trampoline
shim is A tiny Mach-O executable that, at runtime, uses libxcselect.dylib to locate the real tool inside the active developer directory (Xcode or the Command Line Tools) and then execs it

how it works

/usr/bin/git   (shim shared by 78 hard links)
  └─ libxcselect resolves the active developer directory:
       1. env var DEVELOPER_DIR, else
       2. xcode-select -p   (/var/db/xcode_select_link)
  └─ locates the real git under that directory -> exec, forwarding argv unchanged
       1. pointing at CLT → exec /Library/Developer/CommandLineTools/usr/bin/git          # sudo xcode-select --switch /Library/Developer/CommandLineTools
       2. pointing at Xcode → exec /Applications/Xcode.app/Contents/Developer/usr/bin/git # sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer

troubleshooting

xcode-select: error: tool 'xcodebuild' requires Xcode

$ sudo xcode-select -s /Library/Developer/CommandLineTools
$ xcodebuild -version
xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance

$ sudo xcode-select -s /Applications/Xcode.app/Contents/Developer
$ xcodebuild -version
Xcode 15.2

Symbol not found: _XPCTypeBool

[!NOTE] _XPCTypeBool issue is due to CoreDevice (XcodeSystemResources.pkg) wasn't been registered. To fix can execute:

$ sudo installer -pkg /Applications/Xcode.app/Contents/Resources/Packages/XcodeSystemResources.pkg -target /
