Do NOT create your own "myKernel.cl.h"; do NOT add this file to Xcode.
If you did violate this rule (as I did), rename the file (and maybe change the name of the kernel as well) and start again.
Also I also removed the underscores in the kernel definition. Not sure whether this is necessary.
Maybe this might help someone.
