Perhaps it is plain dm-crypt, not LUKS.  (I am not familiar with the 
internals of either, so my understanding is that of a parrot or blind man.)


In the Debian Installer for Stretch:

1.  For "Partitioning method", choose "Manual".

2.  Create partitions, including a partition for swap.

3.  Move the highlight to the swap partition and press Enter to invoke 
the "Partition settings" pop-up dialog, and configure as follows (note 
"Encryption key" => "Random key" setting):

        Partition settings:
            Use as                      physical volume for encryption
            Encryption method           Device-mapper (dm-crypt)
            Encryption                  aes
            Key size                    256
            IV algorithm                xts-plain64
            Encryption key              Random key
            Erase data                  yes
