Does having swap memory damage SSDs too much, what do you think about it?

I did calculate it once on an older samsung drive. If you write multiple terabytes every day, you will cross samsungs estimated lifetime in 3 years.

I have no idea how much data a swap partition move per day but it can't be near that much?

But the swap partition is only used when you run out of ram right? If I have enough ram I should not worry about that.

No, it's used much more often. How often is determined by a value called swapiness.

100% this. An aggressive memory manager could preemptively write everything from memory to swap even though it's still in memory, in case it has to evict it quickly.
