Hey stansdad, sorry to be late on the reply . If you aren’t using STweenableWidget (and if you’re not a coder, you’re probably not using Slate, so you probably aren’t using STweenableWidget) you can just open up XCode and do a cmd+F to find all of the references to STweenableWidget and delete any lines that contain that, but only those lines. You may then need to compile the plugin again, which is a matter of switching your project over to code then opening the project solution in XCode and clicking on build. If you have any more errors let me know.
