Version:
https://developer.apple.com/library/content/samplecode/SourceView/Introduction/Intro.html

Notes:
Issue appears related to the binding of the 'MyOutlineViewController/View/.../Items/Table Cell View' Title and Image views, which are bound to objectValue.nodeTitle and objectValue.nodeIcon, respectively.

As a workaround, I unchecked the "Raises for Not Applicable Keys" binding option for both, which let the application compile and start. 

Configuration:
Attempted on Xcode 8.0 (8A218a) and Xcode 8.1 beta (8T29o), both of which failed
