Homebrew supports and recommends the latest Xcode and/or Command Line Tools available for your platform (see OS::Mac::Xcode.latest_version
and OS::Mac::CLT.latest_clang_version
in Library/Homebrew/os/mac/xcode.rb
).
When a new Xcode release is made, the following things need to be updated:
Library/Homebrew/os/mac/xcode.rb
OS::Mac::Xcode.latest_version
OS::Mac::CLT.latest_clang_version
OS::Mac::Xcode.detect_version_from_clang_version
