This is from the log: Command CoreMLModelCodegen failed with a nonzero exit code

I narrowed it down. It turns out the problem was in the trainingsdata (especially the title row): it contained some umlauts. While create ML was fine with that, Xcode was not. Removing them solved the problem. The model is now recognized in Xcode.

Hi, Thanks for sharing your code and info! so, you did find a work around? Could you you explain how you " changed allItems to a computed var" ? Thanks! Rob
