What behavior are you expecting?

Probably an error message that I can't build iOS project on Windows.

Steps to reproduce:

1. Install v3.0.0-beta8 CLI
2. Go to project directory
3. Run ionic cordova build ios

Post the output of ionic info below please

npm (global):

    @ionic/cli-utils : 0.0.12
    ionic            : 3.0.0-beta8

System:

    Node       : v6.10.2
    OS         : Windows 10
    Xcode      : not installed
    ios-deploy : not installed
    ios-sim    : not installed

Problem persists after running npm i @ionic/cli-utils@beta as we talked about on Slack. Probably more a logic error.

Did you update your plugins, as well?

[janpio]

Those were up to date at the time of writing:

    "@ionic/cli-plugin-cordova": "0.0.13",
    "@ionic/cli-plugin-ionic-angular": "0.0.7",

Ugh, I finally figured this one out. A much better error message will now be displayed for you
