I receive this error when compiling C file in Matlab:
Building with 'Xcode with Clang'.
Error using mex
xcodebuild: error: SDK "macosx10.15.4" cannot be located.
xcrun: error: sh -c '/Applications/
-sdk macosx10.15.4 -find clang 2> /dev/null' failed with exit code 16384: (null)
(errno=No such file or directory)
xcrun: error: unable to find utility "clang", not a developer tool or in PATH

Hi Nisha,
It seems like you do not have Xcode Command Line Tools installed which is necessary to have clang, macOS SDK and other toolchain related commands to be used. Please follow the official Apple Documentation or the link provided by Walter to install them. Later you can use the below link, if you have issues with 64bit API
Hope this helps!
