How to resize an NSImageView in an NSStackView?

Question

I'm working on a project where I want the following in an NSTableViewCell:

• Image

• Text

• Subtitle text

The NSTableView is in a window which the user can expand or contract. When the window expands and contracts, the text wraps as needed.

That much is working.

When it comes to the image view, I can't get the thing to resize at all. I don't understand how the text automatically wraps, but images don't automatically scale. I've been working on iOS so long that I might have missed something in how stack views differ between iOS and macOS, but I never had this problem in iOS.

I don't have much code because the text wraps properly without any code at all, so instead I posted a minimal project showing the problem on Github:

NSImageTableViewTest

Some things I tried:

I have to set the width/height of the image view, or the text won't wrap. It seems to me that the reason why is that if I keep the image view unbound, the table view starts at the width of the image.

I tried setting the leading and bottom constraints of the image view to no avail.

I tried setting the constraints of the NSStackView, but that doesn't help constrain the frame of the image view.

Question: do I have to change the frame of the image view in code? I did try that, to no avail.

At this point, I'm stumped and I'm sure the fix is something easy that I overlooked.

Thanks.

The image view doesn't shrink because the default Content Compression Resistance Priority is too high. Set the Content Compression Resistance Priority to (a bit lower than) "Low (250)".
