Expand description

Return the path of the Swift root.

If the path to libswiftCore is /usr/local/swift/lib/libswiftCore.dylib, this function would return /usr/local/swift.

The path returned here can be overridden by setting the environment variable SWIFT_ROOT.

\return A string containing the full path to the Swift root directory, based either on the location of the Swift runtime, or on the SWIFT_ROOT environment variable if set. The string is owned by the runtime and should not be freed.
