How to implement Equatable protocol for a protocol based on the identity of two instances that implement this protocol?

it fixes the issue There are two problems here. The first is that you can't use ObjectIdentifier on value types. So you must declare this protocol to require reference (class) types:
code :
protocol NetworkSubscriber : class, Equatable {
    func onMessage(_ packet: NetworkPacket)
func ==<T: NetworkSubscriber>(lhs: T, rhs: T) -> Bool {
    return ObjectIdentifier(lhs) == ObjectIdentifier(rhs)

How to make protocol associated type require protocol inheritance and not protocol adoption

This might help you This is pretty interesting. It appears that once you constrain the type of an associatedtype in a given protocol, you need to provide a concrete type in the implementation of that protocol (instead of another protocol type) – which is why your second example worked.
If you remove the A constraint on the associated type, your first example will work (minus the error about not being able to use weak on a non-class type, but that doesn’t seem to be related).

I think the issue was by ths following , The better solution for these kinds of problems is to use composition rather than inheritance. Rather than conform to SlideDismissor, delegate to one.
(I haven't tested this code or even made sure it compiles, but this is the basic approach I would explore.)

What is difference between OUCH protocol and FIX protocol. Message for both protocol looks quite similar

I wish this helpful for you The main difference is that OUCH is a protocol that is specific to the NASDAQ stock exchanges. The FIX protocol is a standard that is supported by most exchanges.
The OUCH protocol is a faster protocol as it is designed as a low level native (binary) protocol, but as it is specific to NASDAQ exchanges you will have to have another module based on FIX to connect and trade on other exchanges.
