Xcode 12 Unable to use Interface Builder to add subview to scrollview

Question

Using Xcode 12 interface builder, I am unable to drag a view into a scrollview. This seems to be a very simple task that was working fine for a few years. I'm not sure what I am missing. Dragging views into other views is working perfectly though.

Answer 1

I have the same issue on Xcode 12.0.1. As a workaround you can start by setting up the root view of your scroll view content, select it and use the Editor / Embed in / Scroll View command (or alternatively, the last bottom right icon in the canvas). Then you can add to the root content view normally by drag & dropping.

Answer 2

I've wasted more time than I'd like to admit on this one. You should drag directly into the drawing canvas, not into the view hierarchy inspector.
