What is the bundle id structure of your System Extension? Does your System Extension contain the container app's bundle id with a unique suffix at the end? For example:

# Container App
com.example.apple-samplecode.TransparentProxyTestBed

# Network System Extension
com.example.apple-samplecode.TransparentProxyTestBed.TransparentProxy

Yes, an ID similar to yours

Okay, thank you for confirming.

Regarding:

perhaps App is not validly structured

Can you provide any more information on why you think the app is not structured correctly?

  • This is an error message from the system when calling [OSSystemExtensionRequest activationRequestForExtension: queue:]: Error Domain=OSSystemExtensionErrorDomain Code=4 "Extension not found in App bundle: perhaps App is not validly structured" UserInfo={NSLocalizedDescription=Extension not found in App bundle: perhaps App is not validly structured}

    I am also facing the same error, any help is appreciated. I also have the similar ID.

  • The result of this error is almost always a configuration issue in your project. Checkout the bundle id structure as I noted above. Checkout that these ids are correctly being referenced in your project. Checkout that you have the com.apple.developer.system-extension.install entitlement set on your container app.

Double check that the String in [OSSystemExtensionRequest activationRequestForExtension:@"HERE"... exactly fits the Bundle Identifier of your System Extension. If you are trying to build an Apple Sample (like "SampleEndpointApp") this is not the case by default as Xcode uses a variable in the Bundle ID ${SAMPLE_CODE_DISAMBIGUATOR}), while the one in code is hardcoded.

In my case I had a whitespace in the Network Extension's product name in the build settings. Removing it solved the issue.
