I added a Content Filter to my app, and when running it in Xcode (Debug/Release), I get the expected permission prompt: "Would like to filter network content (Allow / Don't Allow)".

However, when I install the app via TestFlight, this prompt doesn’t appear at all, and the feature doesn’t work.

Is there a special configuration required for TestFlight? Has anyone encountered this issue before?

Thanks!

What platform is this for?

I suspect you’re targeting iOS, in which case you’re probably hitting the deployment limit for content filters on that platform. TN3134 Network Extension provider deployment discusses that.

OK. But you have the code for the PIRProcessDatabase tool, right? So how about you step through it to see where it throws this error?

Keep in mind that PIR Service Example isn’t a set of tools, like Xcode, where you’re limited to just running the tool and that’s that. Rather, it’s sample code for you to explore, and then use the results to inform the development of the server-side of your system.

Yes, I was following the document and run this on my mac https://github.com/apple/swift-homomorphic-encryption/tree/main/Sources/PIRProcessDatabase

I checked it and can't find exactly where it throws this error.

For the PIR Service Example, yes I understand that. I tried to follow the https://swiftpackageindex.com/apple/pir-service-example/main/documentation/pirservice/testinginstructionsneurlfilter

And expect that it will at least give me a sense of how all of this works. Are you saying that it won't work if we just follow this guide? I want to test if the function is properly working first using the guide. So I can change the configuration later based on my needs.

No, I believe that your saying that (-:

I’m saying that this is open source, which gives you the opportunity to debug these problems yourself, engage with the developers directly, and even submit pull requests with fixes.
