Before Xcode 6, I used to just drag app that corona generates on the device view xcode organizer. Now the organizer has only the apps you build via xcode. I found that you can double click an IPA to open it with iTunes and install in on a device when you synch it with iTunes but that is just a lot of things to do to test a build.
So my question is, how are you installing corona apps on the test devices?
