title: cordova build ios does not create ipa file
body: <p>I am building cordova project for iOS, build log seems fine however I can't find any ipa file generated:</p>
  
  <pre><code>$ npm run cordova platform add ios
  $ cat Build.json
  {
      "ios": {
          "debug": {
              "codeSignIdentity": "iPhone Developer",
              "developmentTeam": "**************",
              "packageType": "development",
              "automaticProvisioning": true,
              "buildFlag": [
                  "EMBEDDED_CONTENT_CONTAINS_SWIFT = YES",
                  "ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES=NO"
              ]
          },
          "release": {
              "codeSignIdentity": "iPhone Developer",
