# CTFontManagerCreateFontDescriptorFromData(_:)

Creates a font descriptor representing the font in the supplied data.

```
func CTFontManagerCreateFontDescriptorFromData(_ data: CFData) -> CTFontDescriptor?
```

## Parameters

`data`

The font data.

## Return Value

A font descriptor created from the data or `NULL` if it is not a valid font.

## Discussion

If the data contains a font collection (TTC or OTC), only the first font in the collection will be returned. Use [`CTFontManagerCreateFontDescriptorsFromData(_:)`](/documentation/CoreText/CTFontManagerCreateFontDescriptorsFromData(_:)) in that case.

> Note:
> The font descriptor returned by this function is not available through font descriptor matching. As a result, you can’t directly look for the font by name with functions like ``doc://com.apple.coretext/documentation/CoreText/CTFontCreateWithName(_:_:_:)``. If you wish to make the font available for name matching, use ``doc://com.apple.coretext/documentation/CoreText/CTFontManagerRegisterFontURLs(_:_:_:_:)`` instead.

## See Also

[`CTFontManagerCreateFontDescriptorsFromData`](/documentation/CoreText/CTFontManagerCreateFontDescriptorsFromData(_:))

Creates an array of font descriptors for the fonts in the supplied data.

[`CTFontManagerRegisterFontURLs`](/documentation/CoreText/CTFontManagerRegisterFontURLs(_:_:_:_:))

Registers fonts from the specified font URLs with the font manager.
