How to link with Apple Frameworks

It is common in MacOS that your Conan package needs to link with a complete Apple framework, and, of course, you want to propagate this information to all projects/libraries that use your package.

With regular libraries, use self.cpp_info.libs object to append to it all the libraries:

def package_info(self):

    self.cpp_info.libs = ["SDL2"]
    self.cpp_info.libs.append("OpenGL32")

With frameworks we need to use self.cpp_info.frameworks in a similar manner:

def package_info(self):

    self.cpp_info.libs = ["SDL2"]

    self.cpp_info.frameworks.extend(["Carbon", "CoreAudio", "Security", "IOKit"])

How to package Apple Frameworks

To package a MyFramework Apple framework, copy/create a folder MyFramework.framework to your package folder, where you should put all the subdirectories (Headers, Modules, etc).

def package(self):
    # If you have the framework folder built in your build_folder:
    self.copy("MyFramework.framework/*", symlinks=True)
    # Or build the destination folder:
    tools.mkdir("MyFramework.framework/Headers")
    self.copy("*.h", dst="MyFramework.framework/Headers")
    # ...

Declare the framework in the cpp_info object, the directory of the framework folder (self.package_folder) into the cpp_info.frameworkdirs and the framework name into the cpp_info.frameworks.

def package_info(self):
    ...
    self.cpp_info.frameworkdirs.append(self.package_folder)
    self.cpp_info.frameworks.append("MyFramework")
