No CSS in iOS after upgrading to rc0

After upgrading my app to the new v1.0.0-rc.0 release css/style is broken on iOS - it looks like the stylesheets are completely missing.
With “ionic serve” everything looks good but “ionic emulate ios” or testing the app directly on an iPhone breaks the stylesheet. I’ve already removed and re-added the whole ios project via “ionic platfomr remove/add ios” - no success.

Any ideas? :-/

Can you check in your www/lib/ionic folder? Make sure you have the right css/scss files.

Thanks for your answer.
css/scss looked ok… even with “ionic serve” css was applied correctly.
However, yesterday I’ve done a complete re-setup of the affected app with rc1 and everything looks good now.
