iPhone (iOS): copying files from main bundle to documents folder causes crash

Question

I am trying to set up my application so that on first launch, a series of files located in the \"Populator\" folder in the main bundle are copied into the documents director

As a general programming practice, it's always best to initialize your variables with a default value:

NSError *error = nil;

In Objective-C, it is valid to send a message to nil. So, in your case, error variable would not cause a crash if it was initialized to nil.
