Xcode ----- Generate Xcode project files. .. versionchanged:: 3.15 This generator supports Xcode 5.0 and above. .. _`Xcode Build System Selection`: Toolset and Build System Selection ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ By default Xcode is allowed to select its own default toolchain. The :variable:`CMAKE_GENERATOR_TOOLSET` option may be set, perhaps via the :option:`cmake -T` option, to specify another toolset. .. versionadded:: 3.19 This generator supports toolset specification using one of these forms: * ``toolset`` * ``toolset[,key=value]*`` * ``key=value[,key=value]*`` The ``toolset`` specifies the toolset name. The selected toolset name is provided in the :variable:`CMAKE_XCODE_PLATFORM_TOOLSET` variable. The ``key=value`` pairs form a comma-separated list of options to specify generator-specific details of the toolset selection. Supported pairs are: ``buildsystem=`` Specify the buildsystem variant to use. See the :variable:`CMAKE_XCODE_BUILD_SYSTEM` variable for allowed values. For example, to select the original build system under Xcode 12, run :manual:`cmake(1)` with the option :option:`-T buildsystem=1 `. Swift Support ^^^^^^^^^^^^^ .. versionadded:: 3.4 When using the ``Xcode`` generator with Xcode 6.1 or higher, one may enable the ``Swift`` language with the :command:`enable_language` command or the :command:`project`. Limitations ^^^^^^^^^^^ The Xcode generator does not support per-configuration sources. Code like the following will result in a generation error: .. code-block:: cmake add_executable(MyApp mymain-$.cpp)
