cordova run ios has stopped working

Question

Suddenly (since yesterday - when I upgraded to OSX 10.12.5) I cannot run cordova run ios from the command line on either the simulator or a physical device.

Any help or hints would be appreciated - I am totally blocked.

I get

I have a DeviceSupport directory...

I have tried to create a completely new project with

$ cordova create MyApp
$ cd MyApp
$ cordova platform add ios
$ cordova run ios

Thanks
