>+        Add a hack just for Evernote linked before iOS 13 that dynamically adds a placeholder -[WKContentView keyCommands]
>+        method (it just calls super). Evernote swizzles the IPI -[WKContentView keyCommands], but this
>+        method may not always be present in the WebKit binary following r240514. So, Evernote may end
>+        up swizzling -[UIResponder keyCommands], but their implementation doesn't account for this
>+        scenario and they end up crashing because they call an unrecognized selector.
>+
>+        * UIProcess/Cocoa/VersionChecks.h: Add version check.
>+        * UIProcess/ios/WKContentView.mm:
>+        (keyCommandsPlaceholderHackForEvernote): Added.
>+        (-[WKContentView _commonInitializationWithProcessPool:configuration:]): Install the hack.
