<p>A manager for a socket.io connection.</p>
<p>A <code>SocketManagerSpec</code> is responsible for multiplexing multiple namespaces through a single <code><a href="Protocols/SocketEngineSpec.html">SocketEngineSpec</a></code>.</p>
<p>Example with <code><a href="Classes/SocketManager.html">SocketManager</a></code>:</p>
<pre class="highlight swift"><code><span class="k">let</span> <span class="nv">manager</span> <span class="o">=</span> <span class="kt">SocketManager</span><span class="p">(</span><span class="nv">socketURL</span><span class="p">:</span> <span class="kt">URL</span><span class="p">(</span><span class="nv">string</span><span class="p">:</span><span class="s">"http://localhost:8080/"</span><span class="p">)</span><span class="o">!</span><span class="p">)</span>
<span class="k">let</span> <span class="nv">defaultNamespaceSocket</span> <span class="o">=</span> <span class="n">manager</span><span class="o">.</span><span class="n">defaultSocket</span>
<span class="k">let</span> <span class="nv">swiftSocket</span> <span class="o">=</span> <span class="n">manager</span><span class="o">.</span><span class="nf">socket</span><span class="p">(</span><span class="nv">forNamespace</span><span class="p">:</span> <span class="s">"/swift"</span><span class="p">)</span>
<span class="c1">// defaultNamespaceSocket and swiftSocket both share a single connection to the server</span>
</code></pre>
<p>Sockets created through the manager are retained by the manager. So at the very least, a single strong reference
to the manager must be maintained to keep sockets alive.</p>
<p>To disconnect a socket and remove it from the manager, either call <code><a href="Classes/SocketIOClient.html#/s:8SocketIO0A8IOClientC10disconnectyyF">SocketIOClient.disconnect()</a></code> on the socket,
or call one of the <code>disconnectSocket</code> methods on this class.</p>
