WKProcessPool

Overview

A WKProcessPool object represents a single process that WebKit uses to manage web content. To provide a more secure and stable experience, WebKit renders the content of web views in separate processes, rather than in your app’s process space. By default, WebKit gives each web view its own process space until it reaches an implementation-defined process limit. After that, web views with the same WKProcessPool object share the same web content process. 

If your app creates multiple web views, assign the same WKProcessPool object to web views that may safely share a process space. Instantiate an instance of this class and assign it to the processPool property of each web view’s WKWebViewConfiguration object.
