# CFBundleCopyExecutableArchitecturesForURL(_:)

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

## Declaration

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

## Parameters

- `url`: The URL to examine.

## Return Value

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.

## Discussion

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