Even 20GB+ swap every day will not significantly decrease the lifespan of the SSD. You will typically want a new computer in about 5 years, and these SSDs usually have 600+ terabytes written as a specification. That is 330GB+ written to the drive every single day - including weekends and it still lasts 5 years. Get more SSD space if you are that concerned about swap. Higher SSDs have higher TBW.
Even if you lose 20 GB in 5 years, you just go on to use then next 20 GB. They are starting out at 256 GB, not 128 like my wife's Mini.
