ApplicationServices framework is not available on iOS?

[st235]

It appears that the ApplicationServices framework is linked across the entire Apple ecosystem in the CMakeLists.txt. When building for iOS both IOS and APPLE flags are defined, therefore ApplicationServices is linked to the target.

However, I believe it is not available on iOS, as generating an Xcode project with SDL3_image linked for iOS results in a build failure.

I am wondering whether I am doing anything wrong or this is really a bug in the build script?

This is my CMakeLists.txt build script if of any use (some details are lifted for the sake of simplicity):

FetchContent_Declare(
    SDL_IMAGE
    GIT_REPOSITORY https://github.com/libsdl-org/SDL_image.git
    GIT_TAG main
    GIT_SHALLOW TRUE
    GIT_PROGRESS TRUE
)

FetchContent_MakeAvailable(SDL_IMAGE)

add_library(core INTERFACE)
target_sources(core INTERFACE
  src/app.h
  src/app.cpp
)
target_include_directories(core INTERFACE ${CMAKE_CURRENT_LIST_DIR}/include)
target_link_libraries(core INTERFACE SDL3::SDL3 SDL3_image::SDL3_image)

And this is the build command I use

cmake -B out/ios -GXcode -DCMAKE_SYSTEM_NAME=iOS -DCMAKE_OSX_ARCHITECTURES="arm64;i386;x86_64"

P.S.: the declaration of SDLIMAGE_BACKEND_IMAGEIO slightly hints that this is only related to Mac OS X.

cmake_dependent_option(SDLIMAGE_BACKEND_IMAGEIO "Use native Mac OS X frameworks for loading images" ON APPLE OFF)

P.P.S.: this stack overflow thread also suggests that ApplicationServices are not available in iOS.

P.P.P.S.: there is also an old unresolved SDL community thread with the similar issue
