prefix attribute must be followed by an interface or protocol (solved)

I had this error while building darling

The fix was to remove from .mm files:

__attribute__((objc_nonlazy_class))

with, from within darling/src/external/objc4/runtime:

sed -i.bak '/__attribute__((objc_nonlazy_class))/d' *.mm

See #964; you're probably using an old version of Clang
