NSIndexSet under ARC Xcode 4.2

[mikeT]

I am trying to work with the three new lookup methods at the end of the chapter but with the lookupAll method I get the following error:
Implicit conversion of 'NSUInteger' (aka 'unsigned long') to 'NSIndexSet *' is disallowed with ARC.
How should this method be written now?
Thanks

Look at the errata.  There were a couple of typos in those examples.

Cheers,
