I m trying to create an xcode project with cpp-swift interoperability(introduced in xcode15) using cmake xcode generator. I m able to invoke cpp code in swift and vice-versa but when opening the project in xcode, the build setting for 'C++ and Objective-C Interoperability' is still set to 'C/Objective C' like in image below. I want to set it to 'C++/Objective-C++'.
I m using the below cmake for this:
. .
add_library(cxx-support ./Sources/CxxSupport/Student1.cpp ./Sources/CxxSupport/Teacher.swift )
#include the directory to access modulemap content target_include_directories(cxx-support PUBLIC ${CMAKE_SOURCE_DIR}/Sources/CxxSupport)
target_compile_options(cxx-support PUBLIC "$<$<COMPILE_LANGUAGE:Swift>:-cxx-interoperability-mode=default>" ) . .
I Have also tried the below in cmake, but it didn't work.
#set(SWIFT_OBJC_INTEROP_MODE "objcxx" CACHE STRING "")
#target_compile_options(cxx-support PUBLIC #"SWIFT_OBJC_INTEROP_MODE=objcxx") Any help on how this can be achieved?
