Deployment to iOS fails in 4.8.2

Deploying to my iPhone is not working. I am getting error messages about a PublicStaging directory not existing, and a failure to create it, and then a failure to start an AFC service.

I was able to deploy under 4.6 a few months ago, as well as with Unity about the same time. This is the first time I have tried since then, now on 4.8.2.

Here is the DeploymentServer log file

Help!

I figured it out! I just had to delete the existing copy of my app from the phone, then it worked.
