How to unset NSFetchRequest's fetchLimit?

Question

The documentation for Cocoa's NSFetchRequest fetchLimit property says:

The fetch limit specifies the maximum number of objects that a request should return when executed.

If you set a fetch limit, the framework makes a best effort to improve efficiency, but does not guarantee it.

However, it doesn't tell you how to unlimit the maximum number of objects that a request should return if the fetch limit has already been set.

How can I return an unlimited number of matching objects after the previously limiting the number of objects with fetchLimit on my NSFetchRequest?

Answer 1

From some quick testing, the default value for fetchLimit when an NSFetchRequest is instantiated is 0, and setting the value to something other than 0 and then back to 0 will not limit the results returned.

So, as of Swift 4, set fetchLimit to 0 to return unlimited results.
