# CTFontManagerCreateFontDescriptorFromData(_:)

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

## Declaration

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

## Parameters

- `data`: The font data.

## Return Value

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

## Discussion

Discussion If the data contains a font collection (TTC or OTC), only the first font in the collection will be returned. Use 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 CTFontCreateWithName(_:_:_:). If you wish to make the font available for name matching, use CTFontManagerRegisterFontURLs(_:_:_:_:) instead.
