Returns an array of CFNumbers representing the architectures a given URL provides.


func CFBundleCopyExecutableArchitecturesForURL(_ url: CFURL!) -> CFArray!



The URL to examine.

Return Value

For a directory URL, if the bundle's executable exists and is a Mach-O file, returns an array of CFNumbers whose values are integers representing the architectures the URL provides. For a plain file URL representing an unbundled executable, returns the architectures it provides if it is a Mach-O file. Possible values are listed in Architecture Types. If there is no bundle executable or if the executable is not a Mach-O file, returns NULL. Ownership follows the The Create Rule.


For a directory URL, this is equivalent to calling CFBundleCopyExecutableArchitectures(_:) on the corresponding bundle.
