You're adding a nil to an array (as the message says)

By a process of deduction, I see that you are adding objects to an array at this line

[tempPeoples addObject:name];

So it is likely that, for this snippet of code, this is where the error happens.

Probably, Not all of the Contacts have a first name, which is likely to be the case for contacts that are businesses rather than people.

You could put a breakpoint in the code and run it through a debugger to see what conditions cause this.
