# The following behavior is regarding the `OS_OBJECT_USE_OBJC` flag. When
# set to `0`, it will allow code to use `dispatch_release()` on >= iOS 6.0
# and OS X 10.8.
#
# * New libraries that do *not* require ARC don’t need to care about this
# issue at all.
#
# * New libraries that *do* require ARC _and_ have a deployment target of
# >= iOS 6.0 or OS X 10.8:
#
# These no longer use `dispatch_release()` and should *not* have the
# `OS_OBJECT_USE_OBJC` flag set to `0`.
#
# **Note:** this means that these libraries *have* to specify the
# deployment target in order to function well.
#
# * New libraries that *do* require ARC, but have a deployment target of
# < iOS 6.0 or OS X 10.8:
#
# These contain `dispatch_release()` calls and as such need the
# `OS_OBJECT_USE_OBJC` flag set to `1`.
#
# **Note:** libraries that do *not* specify a platform version are
# assumed to have a deployment target of < iOS 6.0 or OS X 10.8.
