View code hierarchy

Last modified: 01 August 2022

With AppCode, you can examine the hierarchy of types, method calls, and imports and explore the structure of the source files.

Build hierarchies

When built, a hierarchy can be immediately viewed and examined in the Hierarchy tool window. By default, every new built hierarchy overwrites the contents of the current tab. You can retain the current tab and have the next hierarchy built in a new one.

Build a type hierarchy

  1. In the editor, position the caret at the desired class.

  2. From the main menu, select Navigate | Type Hierarchy or just press ⌃ H.

Different colors of elements stand for different scopes to which these files belong. For example, green by default is used for tests. For more information, refer to Associate scopes with colors.

Build a call hierarchy

Call hierarchies show callers or callees of a method or function.

  1. Open a file in the editor and place the caret at the declaration or usage of the desired method.

  2. From the main menu, select Navigate | Call Hierarchy or press ⌃ ⌥ H.

Build a hierarchy of imports

Imports hierarchies show where the current file is included and track all files included in the current file.

note

This hierarchy is available for Objective-C only.

  1. Open the file in the editor or select it in the Project tool window.

  2. From the main menu, select Navigate | Imports Hierarchy.
