missing package product

Thanks a lot for your detailed explanation of the relevant concepts @DTS Engineer. It's very helpful and I really appreciate your time and support here. I am using Content Filter Extension to capture/log some basic details. As you've mentioned, it's the simplest one. I wanted to have a working network extension app for MacOS to begin with. However, my intention is to capture real network traffic with HTTP/HTTPS logs, actual urls, and actual endpoints along with DNS Record details by using all the relevant extensions together. Right now, My app is working with Content Filter extension. As you suggested, I am building with two Xcode targets, one with Main app and other with the System Extension(which contains multiple network extensions). To start with, I am only focusing on HTTP logs capture using NETransparentProxyProvider for now(Capturing/logging HTTPS requires more work dealing with TLS and Certificates, will look into this later). I am able to build, and run this binary with these added new files for AppP

First off, here: Here's my current personality dictionary. With this dictionary, the driver crashes, presumably in its init. One thing I strongly recommend during early bring-up is that your driver should do as LITTLE as possible. Basically, you can log data... and nothing else. I might not even call super. The problem here is that until you've got a foundation that works in the most BASIC sense (doesn't crash), you'll end up wasting time looking at what you THINK is the problem without actually knowing what's wrong. In any case, this is wrong: IOClass IOSCSIPeripheralDeviceType00 And should be: IOClass IOUserSCSIPeripheralDeviceType00 IOSCSIPeripheralDeviceType00 is the base class driver for mass storage devices. What you want is IOUserSCSIPeripheralDeviceType00, which is the DEXT support driver for SCSIPeripheralDriverKit. In more concrete terms, in the kernel IOUserSCSIPeripheralDeviceType00 is a subclass of IOSCSIPeripheralDeviceType00 which includes a bunch of additional callout hooks which call out to y

We are the VPN developer, and this issue has been reported by one of our customers using our VPN product. It is reproducible only on iOS 26.

I have a similiar network issue but it is with real devices and simulator, after safari 18+ In my case it related to connection lost due to keep alive and the reuse of a dead connections. See: https://developer.apple.com/forums/thread/796906?login=true

While digging into how things are implemented is fun, it’s not the path to long-term binary compatibility. Do not use the code you posted in a product. Rather, follow the advice that I posted earlier, that is, look at how Xcode builds the extension and do what it does. If you do that you’ll see that the build transcript for the link step includes this: …/XcodeDefault.xctoolchain/usr/bin/clang … -e _NSExtensionMain … The causes the linker to set the main entry point to _NSExtensionMain, which is actually a symbol imported from Foundation: % nm -m Packet.appex/Contents/MacOS/Packet … (undefined) external _NSExtensionMain (from Foundation) … This techniques ensures that your extension bootstrap code is revlocked to the system, so it’ll always do the right thing. If you embed the bootstrap in your product, it might fail on future systems. IMPORTANT This is the link step for a packet tunnel provider app extension whose deployment target is macOS 15.5. You might see different commands if you bui
