Following the steps at Building for Smart Watches, I went through a couple of issues listed below:

• I couldn't find the fields WKCompanionAppBundleIdentifier and WKAppBundleIdentifier but I assumed them to be the Bundle identifier field.
• When I ran ns run ios, I got the Multiple commands produce error and I'm stuck there. I tried many suggested solutions but nothing worked so far. Could you please tell me what could be causing the error and if my assumption for the point is correct?
