Is there a way to fetch the current reference count for an NSObject (i.e. NSString)?

You can always check the reference count of a variable by using the CFGetRetainCount function. Note: Reference counting is done only to manage memory for reference types (e.g., classes and closures).
You will need to click on the info descriptor (the 'i' next to Allocation in the left pane) and click on "Record Reference Counts". You can then profile your app and do a search for the specific class you're looking to inspect.
Swift uses Automatic Reference Counting (ARC) to track and manage your app's memory usage. In most cases, this means that memory management “just works” in Swift, and you don't need to think about memory management yourself.

But you should consider using CFGetRetainCount instead
