Apple Updates Xcode to 3.1.3
Apple has released an update to its Xcode application development framework. Xcode 3.1.3 has specific support for iPhone 3.0 development and a small number of bug fixes over Xcode 3.1.2. Problem where Xcode would change your default Keychain has been fixed. Xcode 3.1.3 replaces Xcode 3.1.2 and earlier, or can be installed alongside other versions of Xcode Tools in it’s own Developer folder. You can install Xcode 3.1.3 from the standalone Xcode Tools installer or as part of the final IPhone OS 3.0 SDK installation package. Xcode is now a cross-development system. You can build within it applications for other platforms than the Mac. Currently only the iPhone SDK allows building for the iPhone platform in Xcode, but the SDK format is open and documented, so whoever wants, can supply a Platform SDK that will allow Xcode running on a Mac to build and debug applications for Windows machines, Linux, Embedded systems etc. To achieve this, the Xcode SDK infrastructure was leveraged by inclusion of low-level compilers and tools within the SDK in addition to platform frameworks.
