Hi,
I'm trying to do a really simple thing in theory: load some content programmatically into a scroll view, and then be able to scroll through said content. A screenshot of my storyboard set up can be found here: https://drive.google.com/file/d/1-0P_5jx85H-RpVJM7JFxYCACn8h3mQpm/view?usp=sharing
I dragged an NSScrollView into the main view, and renamed it Scroll View Container. It automatically created those subclasses. The one labeled Scroll View is an NSView. In my Swift code, I add some WKWebView objects and text labels to the Scroll View (NSView) programmatically by doing self.scrollView.addSubview(<new element>). However when I run it and the web views are added, the view still isn't scrollable (see image: https://drive.google.com/file/d/1-bJDxP7UM-r-4rJ6f1MXfMOzd71JnRj_/view?usp=sharing).
I've scoured the internet and tried every possible option I could find: changing the frame height of the NSView programmatically, changing the frame height of the NSScrollView's documentView and contentView, adding a height constraint and updating that in the code, messing with the constraints in the storyboard builder, etc.
I think it might have something to do with the fact that in the first image above you can see the NSView has a handle at the top to change its height by dragging up (which then makes some scroll bars appear in the storyboard view) but no handle at the bottom to change the height by dragging down. And when I add my web views and stuff programmatically, I use their bottom and top constraints to add each element below the previous one. I saw some posts online about an isFlipped property, but I don't know how to change it and am not sure whether that's what I need anyway. Please help!! Thank you!
