An SCNText object is a geometry that creates its contents from a string of text, rendered in 2D and optionally extruded to create a three-dimensional object.

An SCNText object is a geometry that creates its contents from a string of text, rendered in 2D and optionally extruded to create a three-dimensional object.

You provide text for the geometry using an NSString or NSAttributedString object. In the former case, the properties of the SCNText object determine the style and formatting of the entire body of text. When you create a text geometry from an attributed string, SceneKit styles the text according to the attributes in the string, and the properties of the SCNText object determine the default style for portions of the string that have no style attributes. SceneKit can create text geometry using any font and style supported by the Core Text framework, with the exception of bitmap fonts (such as those that define color emoji characters).
