column

Having a traditional 'NavigationSplitView' setup, I am looking for a way to animate it the same as the sidebarView, where there is a button to toggle and it animates by sliding out from the right side of the view, however the closest I have gotten was manipulating the 'navigationSplitViewColumnWidth' but that always results in the view instantly appearing / disappearing. I am using SwiftUI for a MacOS specific app. Here is just a general idea of what I am currently doing, it is by no means a reflection of my real code but serves the purpose of this example. struct ContentView: View { @State private var columnWidth: CGFloat = 300 var body: some View { NavigationSplitView { List { NavigationLink(destination: DetailView(item: Item 1)) { Text(Item 1) } NavigationLink(destination: DetailView(item: Item 2)) { Text(Item 2) } NavigationLink(destination: DetailView(item: Item 3)) { Text(Item 3) } } .navigationTitle(Items) } detail: { VStack { DetailView(item: Select an item) Button(action: toggleColumnWidth) { Text(co

is it really impossible to do this?I tried changing it form the xib designer view and it just reverted back to System font size 11so I tried overriding the header cell, and put my custom font directly to theclass MyTableHeaderCell: NSTableHeaderCell { let customFont: NSFont = NSFont.systemFont(ofSize: 13) // setting the custom font to use on the header cell override func drawInterior(withFrame cellFrame: NSRect, in controlView: NSView) { var mutable = NSMutableAttributedString(attributedString: attributedStringValue) mutable.removeAttribute(.font, range: NSRange(location: 0, length: mutable.length)) mutable.addAttribute(.font, value: customFont, range: NSRange(location: 0, length: mutable.length)) attributedStringValue = mutable super.drawInterior(withFrame: cellFrame, in: controlView) }}this would work most of the time, but sometimes when I move/resize the columns around I would get a crash due to the font's _sharedFontInstanceInfo being nil. _sharedFontInstanceInfo is a private property of NSFontI
