December's CocoaHeads features two great speakers covering two great topics.
"iBeacon Applications" from Andy Craze
Andy says " We'll do a quick overview of
what iBeacons are, look at some of the ways iBeacons can be used for
localization as well as identification, and walk through the sample
applications provided (and perhaps a custom one as well.)"
"Collections: For All Your Stuff" from Joshua Smith
Joshua writes "Sure, you've used NSArray and NSDictionary. But this talk is about
the some of the less popular members of the Collections Classes. I'll
be talking about NSCountedSet, NSEnumerator, NSIndexPath, and
NSIndexSet. This is a talk for those who may be new to
Foundation and will provide a better understanding for some of
the excellent classes available in the Collections Classes."
Also if you have an app you'd like to demo, let me know.
