Quick Documentation Lookup helps you get quick information for any symbol or just method signature information, provided that this symbol has been supplied with documentation comments in the applicable format.
Type inference support in Quick Documentation
AppCode handles the Quick Documentation for the inferred types of symbols for all the supported languages. The IDE infers the type of the expression based on the provided values and renders that information in the Quick Documentation Window.
Documentation comments
AppCode handles the Quick Documentation for a symbol from the line comments that start with the three slashes.
Documentation comments can be applied to the following symbols: class, structure, enum, protocol, interface, variable, property, parameter, method, etc.
