Recent testing stats [0] 've seen are that consumer-grade SSDs are
good for at least 500TB of writes, and many survive well past 2PB.  So
they're unlikely to be significantly degraded even by using them for a
swap drive.  Unless you've got so little swap you're continuously
paging in and out, which case you should spend the money on RAM
instead.
