I have tried to test an iOS application I have been busy creating over the last few weeks on my iPhone. I used Xcode 7 and iOS 8.4 beta for this, since Apple advertised testing without a developer membership subscription on the information site about Xcode 7.
As stated there, I downloaded Xcode 7 and simply logged in in the Xcode Preferences.
Now, when I connect my iPhone it shows up in the devices list, but with "(unavailable)" behind its name, and when I try to start the app it tells me, the Developer Disk Image could not be found.
I would really love to be able to try my app in real before subscribing, please help! 🙂
