I have a working kivy app and it works properly when running from within XCode, I've commented KIVY_NO_CONSOLE=1 btw.
Now when I run it outside of XCode, by tapping the app icon, the following happens (log in the Organizer):
Dec 23 14:20:47 SanderPad btp[822] <Warning>: Initializing python

Could it be a signing issue?
