What are the disadvantages of using a swap file/partition on an SSD, even when swappiness is set to 0

I'm particularly interested in the /proc/sys/vm/swappiness=0 case. How much writes are still done, in practice, to that swap file, and does it have a negative impact to the SSD or any other disadvantage? Or would it nearly compare to not having a swap file?

I am pretty aware of what swappiness=0 means, just not of what it amounts to in practice.

My question stems from a problem I am experiencing without a swap: http://stackoverflow.com/questions/4567972/error-executing-aapt-all-of-the-sudden. There are similar questions regarding SSD and swap but they don't go in-depth into the swappiness=0: Disadvantages of not having a swap partition, Should I keep my swap file on an SSD drive?
