[SwiftUI Bug] TabView image does not show up on MacOS. - liweiyap/text-popover-macOS GitHub Wiki

Apparently, there's a bug with TabView images not showing up at all on MacOS. God knows when the bug will be fixed.

One possible workaround is here. However, I need to consider whether images are truly necessary, for in the Settings Window, they don't add any value besides in terms of aesthetics. Would it be worth the hassle and storage space to download and build a whole new helper repository just for this? In addition, it should be noted that the toolbarItemIcon is of data-type NSImage rather than String; hence, we might be required to amend the source code ourselves.
