Does anyone have a cooking clue what this means and how to sort it out?
It happens when I debug the app from Xcode on the device.
warning: Unable to read symbols for
/Users//Library/Developer/Xcode/iOS DeviceSupport/5.0.1
(9A405)/Symbols/System/Library/TextInput/Riven.bundle/Riven (file not
found). warning: No copy of Riven.bundle/Riven found locally, reading
from memory on remote device. This may slow down the debug session.
It’s harmless, and there’s nothing you can (easily) do to fix it — it’s a glitch in the iOS SDK, or iOS itself, or some combination of the two. Don’t worry about it.
