objc-runtime/include/os/lock_private.h:481:2: Use of undeclared identifier 'os_unfair_lock_assert_owner'
obj-runtime 750 have compile error， but obj-runtim 723 doesn't have.
Objective C runtime is version sensitive, some internal implementations should fit to the specific os. Due to this, runtime may be not compatible with old macOS.
feel free to reopen this issue if you have any questions.
