Why does a phantom horizontal line appear in a macOS SwiftUI NavigationView with a ScrollView?

I have a SwiftUI view on macOS where using a ScrollView inside a NavigationLink within a NavigationView creates an unwanted horizontal line. I've tried different configurations including NavigationView, NavigationStack, and NavigationSplitView, and the issue persists unless I resize the window, which only briefly removes the line.
Here's the code snippet demonstrating the problem:
SWIFTNavigationView { NavigationLink(destination: ScrollView{}, label: { Text("Thing") }) }
I don’t want to hide the toolbar, as my app depends on it. Has anyone encountered this SwiftUI bug and found an effective workaround to remove the divider without sacrificing toolbar functionality?

This isn’t an issue with your code so much as an unexpected artifact in SwiftUI’s implementation on macOS. Many developers have run into a “phantom” horizontal divider (or line) in NavigationView/NavigationLink setups that appears—as you noted—when not resizing the window, and it disappears briefly when a resize forces a redraw.
At the moment there isn’t a public API or officially documented modifier that lets you “turn off” that divider without removing or hiding the toolbar. Workarounds that have been attempted include tweaking the background of the ScrollView (for example, using the new .scrollContentBackground(.hidden) modifier) or wrapping the destination view in extra container views to force a different layout, but results have been inconsistent.
In short, this is a known SwiftUI bug/quirk on macOS. Your best options are to try one of the following:
• Experiment with hiding the scroll view’s background (if the divider is coming from that layer):
SWIFTScrollView { // your scroll content } .scrollContentBackground(.hidden)
• Wrap your destination in another container (such as a ZStack) to see if that forces a different layout that hides the divider.
Unfortunately, if you need the toolbar, there isn’t a “clean” fix at this time. Consider filing feedback with Apple if you haven’t already, as this is a behavior many developers have encountered and it may be resolved in a future update.
Keep in mind that until then you may need to live with or work around the issue using such hacks.
