Xcode problems *** nano328 board is unknown. Stop.

I installed

Xcode Version 9.1 (9B55)
arduino ide 1.8.5 1.8.5 (IDE)
arduino avr 1.6.20 1.6.20 (internal)

I create a new project in Xcode with the lates EmbedXcode 8.2.7 try to compile it and I get the error:

$(error $(BOARD_TAG) board is unknown) <=== *** nano328 board is unknown. Stop. >:(

What I doing wrong here? In previous version of Xcode and EmbedXcode it worked fine.

Does somebody experience the same problems with this combination or knows a solution for it?

Thanks on-forehand.
