 About Xcode and iPhone SDK iPhone SDK and Xcode 3.1.2 developer tools for iPhone OS 2.2 Contents Introduction Compatibility with Mac OS X Versions What's New Installation Deprecation Notice Introduction iPhone SDK for iPhone OS 2.2 is an update and bug fix release to the iPhone OS developer tools. This release includes new, optional GCC and LLVM compilers, updated project assistant, a simplified toolbar, and additional security enhancements. The iPhone SDK includes the complete Xcode 3.1.2 developer tools for Mac OS X development as well as the SDK components for iPhone OS development. We encourage developers to apply to the iPhone Developer Program for access to additional support resources, as well as provisioning resources to enable development directly on an iPhone or iPod touch. For more information visit: http://developer.apple.com/iphone/program/ Compatibility with Mac OS X Versions iPhone SDK requires an Intel-based Mac running Mac OS X Leopard version 10.5.4 or later. Xcode 3.1.2 is also available separately for Mac-only development and is compatible with Intel and PowerPC Macs running Mac OS X Leopard 10.5 and later. What's New • SDK support for targeting non-Mac OS X platforms, including iPhone OS SDK. • GCC 4.2 & LLVM GCC 4.2 optional compilers for use with Mac OS X 10.5 SDK • Updated assistants to create new projects, targets, and source files • Toolbar uses a single popup to choose platform, target, and debug/release • Integrated SCM support now works with Subversion 1.5 About SDKs Xcode 3.1 extended the concept of an SDK (software development kit) to enable Xcode to build, debug, and deploy applications for platforms completely different from that of the host computer.

Within Xcode you can choose specific Mac OS X SDKs to create applications that run on particular versions of Mac OS X, or use the iPhone SDK to build applications for the iPhone Simulator, the iPhone, or iPod touch. The tools included with the SDK will upload your application to a device, and debug directly from the IDE. Xcode for Mac development is included as part of the iPhone SDK installer, and is also available separately with only the Mac OS X SDKs for Mac-only developers. New in Xcode IDE • The assistant interface has been completely revamped, making it easier to create "New Project", "New Target", and "New File" resources. This release of Xcode also adds new assistant templates for both Mac OS X and iPhone OS applications. • A new Overview toolbar item lets you see and set the project's active Target, Configuration, Executable, Architecture, and SDK with a single control. • It is now possible to set a global "override" SDK as the Active SDK, making it easy to test the build of your entire project against a…
