Solution

  • Your Xcode version is probably a version not supported by your Cordova iOS platform. If you downgrade your cordova-ios platform version it should work. Nevertheless I strongly suggest updating your Xcode if possible.

    The change was introduced in version 6.1.0. Check the commit here: https://github.com/apache/cordova-ios/commit/440fc0fe01dabbccfd703ac7854fd24b0b88e1b5

    This means using version 6.0.0 of the ios platform probably works. To install:

    cordova platform rm ios
cordova platform install ios@6.0.0

    But this version has other issues addressed in later patch versions of cordova-ios.
