In an effort to increase its online Intel resources for developers, Apple has launched The Developer Transition Resource Center. Apple bills the site as “your one-stop shop for the information and guidance you need to create universal binaries for both PowerPC and Intel-based Macs.”
Documentation and QuickTime videos on the site are categorized in four ways: Universal Binaries; Xcode 2; Porting from CodeWarrior; and Optimization.
Articles available to read include Adopting Universal Binaries on Mac OS X, Working with Xcode: Building Applications for the Future, IA-32 Intel Architecture Optimization Reference Manual (PDF), and Porting CodeWarrior Projects to Xcode, among many others.
