What is your output for cordova platform?

$ cordova platform Installed platforms: ios 3.9.2 Available platforms: amazon-fireos, android, blackberry10, browser, firefoxos, osx, webos

With ios 4.0.0 I had the same error. I changed the platform version and it worked.

$cordova platform remove ios $cordova platform add ios@3.9.2
