A read-only array of term pairs, each in a lexicon entry object, for use by a custom keyboard.
- iOS 8.0+
- Mac Catalyst 13.0+Beta
To obtain the lexicon, call the
request method of the
UIInput class. This method can be called only from a custom keyboard app extension. A lexicon contains words from various sources, including:
Unpaired first names and last names from the user’s Address Book database
Text shortcuts defined in the Settings > General > Keyboard > Shortcuts list
A common words dictionary
Apple intends for you to consider the words in a lexicon object as supplementary to an autocorrection/suggestion lexicon of your own design. For information on custom keyboards, see Custom Keyboard in App Extension Programming Guide.
