I'm using Apple Clang to build a C++ project from the terminal. The following lines are printed when building the project: -- The C compiler identification is AppleClang 15.0.0.15000100 -- The CXX compiler identification is AppleClang 15.0.0.15000100 "clang --version" and "gcc --version" commands show me the following: Apple clang version 15.0.0 (clang-1500.1.0.2.5) Target: arm64-apple-darwin23.3.0 Thread model: posix The next function, while valid with other compilers, displays an error for Apple Clang: std::vector<char> read_file() { return {}; } error: non-aggregate type 'std::vector<char>' cannot be initialized with an initializer list return {}; My questions: Am I on the latest Apple Clang version? If not, how can I upgrade to it? So far, I've tried: "xcode-select --install" command, the result: xcode-select: note: Command line tools are already installed. Use "Software Update" in System Settings or the softwareupdate command line interface to install updates "softwareupdate -l" command, the result: Software Update Tool Finding available software No new software available. The installed XCode version on my MacBook is 15.2
