A new function in Xcode 7 is that I can test my apps on iOS devices without a paid developer account.
It works fine on my iPad air, but when I tries with my iPhone 5s I always get some kind error message.
I have tried with multiple Apple-ID's, and i have restored my iPhone (from a backup)
I have tried with one of my friends iPad, and it worked fine.
I hope some of you can help me.
The message xcode gives when trying to install an app on iPhone.
