Rick, referring to the coincidence with your other post yesterday, it seems like you’re working on the same app I was working on earlier last year :) From my experience, I would say: Don’t push too hard on Auto Layout with NSSplitView. I would remove that >= 200 constraint and set the split fraction in your storyboard, or programatically. Although it’s solving a slightly different problem than yours (actually, kind of the opposite sidebar behavior), you might want to have a look at this demo project. https://github.com/jerrykrinock/SplitViewSidebar It shows how to set and "constrain” split view sizes, and contains some useful comments and tips regarding NSSplitView and Auto Layout. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
