The CTFont opaque type represents a Core Text font object. Font objects represent fonts to an application, providing access to characteristics of the font, such as point size, transform matrix, and other attributes. Fonts provide assistance in laying out glyphs relative to one another and are used to establish the current font when drawing in a graphics context.

Name specifier constants provide access to the different names associated with a font.
These constants provide keys to font variation axis dictionary values.

enum CTFontThese constants represent the specific user-interface purpose to specify for font creation.
typealias CTFontFont table tags provide access to font table data.
struct CTFontThese constants describe font table options.
struct CTFontThese constants describe options for font creation and descriptor matching. They are used by the functions CTFont and CTFont.
The CTFontCollection opaque type represents a font collection, that is, a group of font descriptors taken together as a single object.
The CTFontDescriptor opaque type represents a font descriptor, that is, a dictionary of attributes (such as name, point size, and variation) that can completely specify a font.

The CTFramesetter opaque type is used to generate text frames. That is, CTFramesetter is an object factory for CTFrame objects.
The CTGlyphInfo opaque type enables you to override a font's specified mapping from Unicode to the glyph ID.
The CTLine opaque type represents a line of text.

The CTRun opaque type represents a glyph run, which is a set of consecutive glyphs sharing the same attributes and direction.
The CTRun opaque type represents a run delegate, which is assigned to a run (attribute range) to control typographic traits such glyph ascent, glyph descent, and glyph width.
The CTTextTab opaque type represents a tab in a paragraph style, storing an alignment type and location.
