An application which worked on previous versions of MacOS fails on High Sierra with the following message:
dyld: Symbol not found: _OBJC_IVAR_$_NSScroller._action Referenced from: Expected in: /System/Library/Frameworks/AppKit.framework/Versions/C/AppKit
What change might lead to this issue? (I am not expert in MacOS development) I suspect otool command might help identify changes related to this problem but haven't worked out the right parameters for it yet.
Checking AppKit documentation https://developer.apple.com/documentation/appkit/deprecated_symbols it says NSDrawer is deprecated, is this related?
NSDrawer [deprecated] A user interface element that contains and displays text, scroll, and browser views, in addition to other view subclasses.
