why is xcode 7 not running an app on ios 9?

Question

Lately installed Xcode 7 beta 4. My app will not run on an iOS 9.0 device, although it will run on an iOS 9.0 simulator, and an iOS 8.4 device (using Xcode 7b4).

Xcode shows "Running %app_name on %device_name", the icon shows up on the device, but does not run, and that's how it stays.

Debug console shows nothing (checked the preferences, also, when using an iOS 8.4 device it shows output log as expected).

Another app that I created runs fine, it's just this app, on iOS9 device (Sim works smoothly).

No exception is thrown, no compilation error... nothing to go on.

Trying to start the app from the phone itself results in a request to send notifications (ok behaviour) and crashes...

Any ideas ?

EDIT:

In the device console output, I these two messages (not always):

Aug 4 11:39:53 iOS-9-test-device syslog_relay(liblockdown.dylib)[117] : The connection is now invalid. Aug 4 11:39:53 iOS-9-test-device lockbot[79] : got an unknown event

And this is a crash report from the device itself :
