file abc.d:

module my.abc;

class Abc
{
     private int x;
     this() { this.x = 1; }
}

and xyz.d:
==
module my.xyz;
import my.abc;
class Xyz: Abc
{
     this() { super(); this.x = 2; }
}

Compilation fails with "Deprecation: my.abc.Abc.x is not visible 
from module xyz"

As I understand, the reason is

But how can I use private fields from descedant class?

You don't, the whole point of private is that they aren't used 
from outside the module.

Try `protected` instead, it is similar to private, but still 
allows use from a subclass.
