'-[UIDevice uniqueGlobalDeviceIdentifier]: unrecognized selector sent to instance 0x68170c0

It looks like UIDevice+IdentifierAddition.m is not being compiled. To check / add it: Click on the project in the navigator on the left in Xcode. Select the app target. Select the 'Build Phases' tab. Open up 'Compile Sources'. Check that UIDevice+IdentifierAddition.m is in there. If not, then click the '+', select it and click add. The exception points to this as the fix because it's saying that there is no method on UIDevice called uniqueGlobalDeviceIdentifier, which is added by the category.
