In support of today's release of iOS 4.3.2, Apple has also pushed out Xcode 4.0.2 for developers, offering updated tools for iOS and Mac OS X application development.
Xcode 4.0.2 is available free of charge to members of Apple's paid developer programs, and non-members can purchase the application for $4.99 in the Mac App Store, although the Mac App Store is currently still showing the older Xcode 4.0.1 version.
