A 'Hello World' for iOS Network Extension content filters?
I've just started looking at Network Extensions for iOS. Specifically, content filters. Is there any current example code for how to constuct a *very* basic Network Extension content filter? Something very simple, like a content filter which denies all network connections when it's active.The previous reference code at ( SimpleTunnel: Customized Networking Using the NetworkExtension Framework ) is in Swift 3 and no longer builds in Xcode 11.1. The documention at ( NetworkExtension | Apple Developer Documentation ) describes what is in the related classes, but doesn't have much about how to use the framework.Some example or reference code around Network Extension content filters would be very helpful. It looks like there are many moving parts and settings around Network Extensions. Some working examples would go a long way to helping developers new to the framework understand how to use it.Thanks!
