xcrun:tldr:02b42

The command "xcrun --toolchain ${name}" is used in the macOS Terminal to switch between different toolchains (sets of tools and compilers) in Xcode.

Here's how it breaks down:

• "xcrun" is a command-line utility in macOS that allows you to locate and run various developer tools provided by Xcode.
• "--toolchain" is an argument that is used with "xcrun" to specify the toolchain to use.
• "${name}" is a placeholder that represents the name of the desired toolchain. You need to replace "${name}" with the actual name of the toolchain you want to use.

By using this command and providing the correct toolchain name, you can change the default set of tools and compilers used in Xcode, allowing you to work with specific versions or variations of toolchains for development purposes.
