I tried to download and compile https://developer.apple.com/library/content/samplecode/SourceView/Introduction/Intro.html

I have:

Xcode Version 8.0 (8A218a)
macOS Sierra 10.12 Beta (16A313a)

I get the following error:

/Users/test/Downloads/SourceViewUsingNSOutlineViewwithNSTreeController/SourceView/Base.lproj/Main.storyboard: Exception while running ibtool: [<__NSCFConstantString 0x10db4cca0> valueForUndefinedKey:]: this class is not key value coding-compliant for the key nodeTitle.

Does anyone has a clue on how to fix this?

Thanks

It's some kind of bug compiling storyboards in older formats. The only workaround I found (in a different project) was to set the file format to 10.12 (in the File panel of the Utility inspector) instead of the deployment target version. (FWIW the 10.12 format worked OK on 10.11, too, perhaps only by luck.)

My bug report was #28037221, closed as a duplicate of still-open #19669391, if you want to add your vote. 😉

Thank you!

I guess it's a fine workaround when working with sample code but not ideal in other cases 🙂

And… yes it works!
