Question

Answer 1

A segfault is unlikely to be a build error. To reproduce this problem, try clearing out any saved information on the iPhone simulator before running the project; it is possible that you are assuming the existence of certain entries in NSUserDefaults that are present on your own iPhone, but which would not be available on a default installation. If that doesn't reproduce the problem, then you should create unit tests for each of your components, ruling out each component at a time as the cause of failure. Eventually, you will have ruled out every cause of failure except for the true cause of failure.
