Object won't highlight in the 3d viewport This was working fine until I exited blender without saving my file.  When I restarted blender 2.8 and opened my file when I click on an object it highlights in the Scene Collection but not in the 3d Viewport. I am able to manipulate them but I need to see what I have selected.

Maybe you deactivated the Outline in the Viewport Overlay? In Object Mode, click the arrow next to the Overlay button (top right) and make sure the box is checked.
