I'm using Xcode 8.2. I created a custom NSView that I will be adding to various NSViews. However, when I run the app, one of the buttons doesn't honor the trailing space when the window grows. Why not?
Custom subview uses the recently re-introduced springs and struts. Action button should maintain a constant trailing space:
The view that includes the custom subview also uses the spring and strut mechanism. It is set to expand with the window:
When the app runs, the custom view frame grows as it should, but the action button is not in the proper place. This is what Xcode shows for the frames:
I also tried using normal constraints and I got the same results.
