This is the signature of s7_integer:

 s7_int s7_integer(s7_pointer p);

so both the xcode warning and auto-fix seems correct. The problem must
be elsewhere.
Perhaps the signature of s7_obj_to_max_atom should really be

 t_max_err s7_obj_to_max_atom(s7_scheme *s7, s7_pointer s7_obj, t_atom *atom);

?
