Objective-C/C++

Last modified: 11 January 2023

CLion enables you to work with Objective-C/C++ files as comprehensively and productively as with code written in C or C++.

tip

CLion doesn't provide application support for Objective-C/C++. To build and run XCode/Objective-C projects, we encourage you to switch to AppCode

You can open, create and add Objective-C/C++ files with .m and .mm extensions into your CMake or compilation database project, and use all of the features for code inspection, assistance and refactoring that CLion provides. Live and code templates are also available for Objective-C/C++ code. For more details, see CLion Features in Different Languages.

To configure Objective-C/C++ specific settings, use the following pages of the Settings dialog Ctrl+Alt+S:

  • Editor | Inspections | Objective-C

  • Editor | File and Code Templates (and select the Code tab)

  • Editor | Live Templates

Enable code style and color scheme settings for Objective-C/C++

  1. Press Ctrl+Shift+A or choose Help | Find Action from the main menu. In the popup that opens, start typing Registry, select the corresponding item and press Enter.

  2. In the Registry dialog, start typing clion.enable.objc.settings and select the checkbox next to the corresponding key:

  3. As a result, Color Schemes and Code Styles pages of the Settings dialog now cover Objective-C/C++:
