|In the wake of the public launch of iOS 6.0.1, Apple has also released the first betas of iOS 6.1 and Xcode 4.6 to developers. While the Xcode release is likely meant to support iOS 6.1, it's not clear what most of the changes in the latter include.
One known improvement involves the Map Kit. "The Map Kit framework now lets you programmatically search for map-based addresses and points of interest," Apple writes. "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."
