iOS build failed using Legacy build paramater Ionic 3

Ionic Framework ionic-v3
1

First time trying to build Ionic app on apple in probably a year.
Was using the command line to use the Legacy Build flag(?). Getting an error that it wants to start some emulator. I just want it to build code.

here is the error.

[10:01:54]  build dev finished in 14.96 s 
> cordova build ios --buildFlag=-UseModernBuildSystem=0

I opened up Xcode and change it to Legacy in there, no difference.
