Hi Brad, Unfortunately no :( Our companion app got rejected last time from AppStore and we are currently fixing the issues. They are not related to NativeScript, but it will take some time for the app to get published on the App Store with the latest NativeScript runtime enabled.
That said you can still deploy on your device, but not by using the companion app. With the latest update of AppBuilder we enabled cloud builds for the applications, so you can instruct AppBuilder to use your iOS provisioning profiles and create an IPA file which you can then ad-hoc deploy to your devices. Here is how to set your provision profile - http://docs.telerik.com/platform/appbuilder/code-signing-your-app/configuring-code-signing-for-ios-apps/create-ad-hoc-provisioning-profile

We have a release 0.4 scheduled for next week and hopefully by then we will have the companion app updated and you will not need to do this, but for the moment this is the only option for you.
Please let me know if you have any questions!
