I "discovered" that if power state of lightbulb is 0 you can not read or write brightness level.
To get over this issue I read power state and if it was 0 I changed it to 1 first then change brightness level.
When reading brightness level just to show on screen if power state was 0
I just made it 0 in my indication system.
It is a shame that I could not read this in documentation.
I found the reason.Some of the nodes did not have geometry because they should not be seen.When .runAction executed for a node without geometry it takes a bit of memory and they add up.I've just get rid of nodes without geometry.

First copy your projects to an other folder or to an external drive or both to be extra safe. Then erase everything about Xcode. Then install new one. That is what I did and worked very good.
