I finally got my watch application build successfully but I'm getting this error message when I try to debug on the device.
The WatchKit app's Info.plist contains a key that is not in the whitelist of allowed keys for a WatchKit app.
Here is my plist
<key>CFBundleDevelopmentRegion</key>
<string>$(DEVELOPMENT_LANGUAGE)</string>
<key>CFBundleDisplayName</key>
<string>AIM WatchKit App</string>
<key>CFBundleExecutable</key>
<string>$(EXECUTABLE_NAME)</string>
<key>CFBundleIdentifier</key>
<string>$(PRODUCT_BUNDLE_IDENTIFIER)</string>
<key>CFBundleInfoDictionaryVersion</key>
<string>6.0</string>
<key>CFBundleName</key>
<string>$(PRODUCT_NAME)</string>
<key>CFBundlePackageType</key>
<string>APPL</string>
<key>CFBundleShortVersionString</key>

<key>CFBundleVersion</key>

<true/>
Comparing to a WatchOS plist in one of my open source apps - https://github.com/bravelocation/yeltzland-ios/blob/master/watchkitapp/Info.plist - I don’t have a NSExtension key.
That would be the first key I’d delete to see if it was the culprit.
