New APIs in iOS 7
For the longest time, this boringly essential function [Base64] was completely MIA, leaving thousands of developers to copy-paste random code snippets from forum threads. It was an omission as conspicuous and annoying as JSON pre-iOS 5.
Lots of great stuff, including Base64, NSURLComponents (sorely needed), blink and smile detection, barcode scanning, and access to Safari’s Reading List. I’ll be interested to see whether NSProgress takes off.
