XCode showing Error Provisioning profile "Mac Team Provisioning Profile: com.ciphercloud.macapp.CipherCloud" doesn't match the entitlements file's value for the com.apple.developer.networking.networkextension entitlement.
To sort this out, try and take a look at what entitlements are contained in your provisioning profile for your Container app and your Network System Extension:
$ security cms -D -i yourProfile.provisionprofile
Then cross reference these entitlements from your profile against the entitlements declared in your entitlements file for both your Container app and your Network System Extension. Make sure that the group of entitlements that are declared in your entitlements file for each of your Xcode targets are at least contained in each of your provisioning profiles.
