Along with a slew of software updates for OS X and iOS, updates for supporting applications on both platforms and firmware updates for the latest models of MacBook, Apple has also taken Xcode 4.5 out of beta. The integrated development environment (IDE) for OS X Lion and Mountain Lion (10.7.x and 10.8.x) is free to registered Apple Developer Connection (ADC) members, and despite running on Intel Macs only can create programs that are both PowerPC and Intel compatible. The new version offers Auto Layout for both OS X and iOS, an OpenGL debugger and more.
