Can not simulate ios app in El Capitan

[endymion00]

I'm experiencing some issues trying to build the app for ios simulator.
First it is needed to create a "www" folder inside project root folder (see: ionic-team/ionic-cli#935)
Also ios-deploy version and ios-sim version must be installed.

But the following command does not work: ionic cordova prepare ios
Error message is "cordova is not a valid task".

How can I build the app?

ionic version: 2.2.1

ionic info result:

You're using an old version of Ionic 2.2.1. The latest version is 3.20.0.

Hi, you were. I updated to ionic 3.
However another error occurs when executing ionic cordova run ios --emulator

You’re not using latest XCode 9. always install latest XCode, the moment it’s released.

I see. I hoped to avoid that because currently i can't upgrade my OS due to other development requirements.
Thank you very much. I'm looking forward to test this amazing project as soon as possible :)
