There used to be a way to do it for iOS8 but I am not sure if now that we have TestFlight or that iOS 8.3 filesystem restriction, apple is not letting us do this anymore:

I am trying to do it on 10.11 beta (15A216g) but I could not do it on Yosemite either.
PS. The app on that post works well enough on iOS9 beta. I am trying to sign a beta app which the UDID of my phone was not included :-/
