Customize Sidebar Default Width

[wigging]

I labeled this as a bug for now. Hopefully there will be a SwiftUI update that fixes the problem. I'll keep this open so I don't forget to about it.

I added a sidebar-width example. It uses minWidth to define the initial width and maxWidth to define the max width of the sidebar. Does that demonstrate what you're trying to accomplish?

Thanks! In the example I'd like to show the window with the sidebar initially set to something like 225 pt or 250 pt and still allow it to be resizable down to 200 pt and up to 300 pt.

Apps like Notes or Finder generally have the same behavior... the window shows with the sidebar width greater than the minimum and less than the maximum. I haven't figured out how to accomplish that in SwiftUI.

I understand what you're saying but I don't think it is currently possible in SwiftUI. One thing I tried was to remove .listStyle(SidebarListStyle()) from the example. This prevents the sidebar from collapsing but the nice styling effect is gone.

It's a bummer it doesn't seem to be supported in SwiftUI but thank you for taking a look! I really appreciate it!

As of macOS 13, this can be accomplished in SwiftUI with the navigationSplitViewColumnWidth function. See the article I posted at https://gavinw.me/swift-macos/swiftui/twocol-navsplit.html for more details.
