How to build app with CLI 3.3.x?

I just updated CLI to 3.3.3 and I can’t anymore build my app. Please see the screenshot below. How may I build my app now ? Do I need to upgrade to paid account ??

How did you build before?

I don’t want to see a screenshot. I want to read an error message.

I just did ‘ionic build ios’, but this command is no longer supported

And what does it tell you when you execute the old command?

Just use ionic cordova build ios.
