NSSplitVIew - auto saving divider positions doesn't work with auto layout enabled

Question

With auto layout enabled, auto saving divider positions by setting an autosave name for the NSSplitView in interface builder results in each divider being completely collapsed on an app restart. Disabling auto layout allows auto save works perfectly.

I have tried this in a new Xcode project as well, same result. Is this a bug, or a known incompatibility?

How could I work around this (or is there a fix to this, if it is a bug)?

Answer 1

I found that setting Identifier and Autosave within a Storyboard with autolayout enabled doesn't work. However it did work for me once I set the autosaveName programatically.

class MySplitViewController: NSSplitViewController {

    override func viewDidLoad() {
        super.viewDidLoad()            
        splitView.autosaveName = "Please Save Me!"
    }
}

        

Answer 2

I ran into this problem as well, and I found that I need to set both the identifier and the autosaveName values for the NSSplitView, and that they need to be set to different values.
