Just hours after releasing iOS 6.0.1 to the public, Apple has released iOS 6.1 to developers. The new version, which is available through the company’s developer site, is the first such beta to arrive for all developers for iOS 6. This beta is for iPhones, iPads, and iPod touches. A beta version of the upcoming Xcode 4.6 is also available.

As 9to5Mac first uncovered, iOS 6.1 beta includes some changes to the Map Kit searching in Maps for developers:

The Map Kit framework now lets you programmatically search for map-based addresses and points of interest. The MKLocalSearch class initiates a search for map-based content using a natural language string. In other words, you can enter placename information or portions of an address and have Map Kit return search results that match the information you provide. For example, searching for the string “coffee” would return the location of local coffee bars along with information about each one.

We’re still digging and will let you know what else we find about iOS 6.1 as warranted.
