No. writeToFile: writes a property list representation of the dictionary and 
from the above you can see that NSDictionary must have String keys to be a 
property list.

You could turn it into NSData and write it like that perhaps.

Thanks for your reply.
I don't see why it have to be strings, just because it will be an XML file, but if it's not possible than that's OK for me. I just hoped that using NSNumber would make it faster (to look up), since it requires less conversions.
