###### CONSISTENCY BETWEEN MACOS AND IOS #####
#
# In order to use the same PodFile with MacOS, we need to unlink the libraries that do not support Catalyst, filter
# files in native targets build phases, filter dependencies and make sure the unsupported frameworks along with their
# their bundle resources are not included in the final archive. For that, we use `platform_filter` to specify 'ios' and
# 'OTHER_LDFLAGS[sdk=iphone*]' to link those libraries for iPhone and iPad. Besides, we modify "*frameworks.sh" and 
# "*resrouces.sh" to skip installation for architecture x86_64.
#
# *Notice*: 'sdk=iphone*' excludes macOS, even though Catalyst is compiled with iOS SDK.
