You are right. Thank you for pointing out
this trap.

I agree with you that the compiler should warn
about this. I thought that 'unowned' is like
bare pointers; if you use them, you take care of
memory, not the compiler. But this default
unowned means that the compiler must be
responsible, not the programmer.


Nice day
