Description gchatz 2015-12-08 19:02:57 PST 
Summary:
When navigating to web sites, the didFinishNavigation callback from WKNavigationDelegate can be called before the main frame load completes, which is not allowed according to the documentation. I have seen this happen with sites like nytimes.com, techmeme.com, and gmail.com.

Steps to Reproduce:
1. Put a breakpoint on the didFinishNavigation method.
2. Run app using WKWebView.
3. Navigate to nytimes.com.

Expected Results:
Breakpoint is hit, and the nytimes.com main frame is fully loaded.

Actual Results:
Breakpoint is hit, but the nytimes.com main frame is not fully loaded. 

Version:
iOS 9.1

Is there a suggested workaround?

This happens on iPad and iPhone, most dramatically on iPad.
