WireGuard is broken on iOS 15 beta

[Andrej Mihajlov]

My approach worked too. However it relies on the private interfaces of NetworkExtension framework, which we’d probably want to avoid.

In short it can be expressed in one line as:

let fd = packetFlow.perform(Selector("interface")).toOpaque().advanced(by: 0x128).assumingMemoryBound(to: Int32.self).pointee

But I bet that walking over fds is much safer.

Cheers,
Andrej
