# NSFontFamilyClass

Constants that classify certain stylistic qualities of the font.

```
typealias NSFontFamilyClass = UInt32
```

## Discussion

These values correspond closely to the font class values in the OpenType OS/2 table. The class values are bundled in the upper four bits of [`NSFontSymbolicTraits`](/documentation/AppKit/NSFontSymbolicTraits) and can be accessed via [`NSFontFamilyClassMask`](/documentation/AppKit/NSFontFamilyClassMask). For more information about the specific meaning of each identifier, refer to the OpenType specification.
