<p>The problem is that I need a way to refer to a function with a specific name. Plus the connection type has to have a specific API, like having a DispatchQueue and know the router object if there is any (sounds like a protocol right?!). The function reference should also keep the connection object alive with a strong reference. </p>
<p><code>associatedtype</code> does not solve that problem for me.</p>
<p>I clearly see that generic protocols overlap with <code>associatedtype</code> but couldn’t we find a compromise here? For instance like Chris Lattner introduced generic type aliases without the ability of constants.</p>

Not really:
<div class="">Take a look at (for example) AnyIterator… this whole
layer of indirection could be removed with the requested
change.</div>
<div class="">You can declare a protocol that generates Ints,
Strings or whatever you like — just not in a generic way, and
that's a pity.</div>
