NSSourceList text not visible

I got everything working for my hierarchical view, using NSOutlineView and bindings.

Then, I thought I would try out NSSourceList (which is an NSOutlineView with the appearance set to sourceView) and, even with everything apparently configured the same, apart from the appearance, the arrows on the "group" nodes are visible but not the text on any of the nodes.

Any ideas?

This question seem to be about macOS development with AppKit, and not about Swift per se. Although you probably use Swift to develop this, it isn’t really Swift related.

I recommend the Apple Developer Forums over at Apple’s website.

You're right. I've done just that. Thanks.
