Build failure when I run iOS production build

Ionic Framework ionic-v3
1

I ran
ionic cordova build ios --prod

my build failed I can’t seem to figure out if I didn’t run the correct directory or if xcode is my issue. I am new to all this.

Can you try the same with a new, blank project? Create one with ionic start blank blank. Report back if this worked or if you also get this error.
