WKWebView vs SFSafariViewController

Question

We have WKWebView in iOS 8 and SFSafariViewController in iOS 9. I know that WKWebView subclasses from UIView, and that SFSafariViewController subclasses from UIViewController.
They are essentially different.

My question is about memory management between these two components.

WKWebView — that actually performs most of its work in a separate process, which means that most web-view-related memory usage would not be attributed to our process.

This helps a lot in preventing our app from being killed because our process consumes a large amount of memory.

Does SFSafariViewController handle web-view-related memory in a separate process like WKWebView?

Answer 1

Yes, Safari View Controller runs in a separate process from your application. Here's a link to WWDC session.
