On my phone so I haven't ran any test code; first thoughts are below. I might see other issues when sitting at a large screen.

Assuming that inputArray is in fact an NSMutableArray (not just cast as such) this should work.

You should use fast enumeration if possible, e.g.:
for (NSString *fileName in files) {}

It strikes me that here is where you are explicitly calling [NSArray objectAtIndex:], which I am pretty sure internally uses the corresponding core foundation call that errors out on you. Are you sure you don't have a typo and are referencing inputArray instead of files? (This is why my comment at the beginning was important.)

This is a lot of supposition. Do you have a backtrace you can inspect ("bt" in gdb)?
