Could not connect to debugger on iPhone

Hello!

My MonoDevelop-Unity can't attach to my game running on an iPhone. I've searched around and tried various things, but to no help. I'll give as much information about this as possible:

• I'm running Unity 5.2.2f1

• The application runs well on Windows, Osx and Android

• I build the application in Run in Xcode as Debug, with development build and script debuggning enabled.

• I compile the project in Xcode and launch it directly from Xcode on an iPhone 4s.

• I can attach the profiler without a problem

• I get console output in Xcode

• The mac and the iPhone are connected to the same WiFi network

• I can see the iphone in the "attach to device list", but after choosing it i get the "Could not..." message after a second or so. If there's any other information that you think could help, please ask and i'll provide it.

• the iphone is running on iOS 7.1.2
