so could someone tell me what WWDC means for developers?
So, you want to know what the conference itself means to developers? I think you'll get as many answers as there are developers, but here's my take on it: WWDC, for those attending, is an opportunity to attend sessions on specific topics of one's interest, talk with Apple engineers and fellow developers, and find out much more on what is "the latest and greatest". For those not attending, information from the conference will trickle down to us, some of it perhaps quickly, some more slowly. It also means an updated Mountain Lion developer preview and the release of iOS 6 beta.
In terms of the release of iOS 6, to me, it means a whole new set of functionality and APIs that I should evaluate and determine how it affects my existing apps as well as apps in development. Perhaps there are some methods that are now deprecated; I should find alternatives if I wish to have warning-free code. I, at least, should look at all the documentation that Apple has provided alongside the release of iOS 6 and Xcode 4.5 and read through
all of it. Also, I will keep an eye out for articles from other developers talking about what's new with iOS 6. For example, this one:
iOS 6 features you might have missed. In the "Other features" section, it talks about "pull-to-refresh on Table views" and "rich text on label fields and text views". I am interested in learning more about these, along with many other things.
