I hiked with a group of 10 back on Friday 6/17. As of that time things were melting very fast. If you are planning to hike going forward I doubt you will run into tough spots to the degree that we did late last week. As others have mentioned there were only two spots on the switchbacks that were of any concern. One was around the top of the cables where we had to cross to the outside while hanging onto the cables them jump across and onto a very ice covered spot. We actually chopped up most of the ice there for later hikers that morning to make it a bit easier/safer. At the top of the switchbacks there was that remaining snow covered area that some kind of foot traction would have made easier. The chute has melted to the degree that it has become less viable as a way up/down. I saw people hiking without any extra traction even at that time although I would certainly not have recommended it at the time. By now however, you should be fine.
