Yes, the Interactive Physics Editor works great in Blender 2.8. You'll find it has a new home in the right-side tool panel in the 3D viewport!
NOTE: Blender 2.8 is still in Beta, and every day a new build is released which could introduce compatibility issues with the Interactive Physics Editor. If you run into an issue, first make sure you are using the latest 2.8 build from blender.org. If the issue persists, be sure to report the issue in an email to firstname.lastname@example.org and we will address it right away.
