Chapter 1: Introducing Xcode 4

NOTE

Xcode doesn’t include network deployment features. But it does create application binaries that can be handed to net-

work deployment tools.

Earlier versions of Xcode supported universal binary development, which was backward-

compatible with PowerPC hardware. Although OS X 10.6 Snow Leopard was the first Intel-only

version of OS X, Xcode supports universal binaries for Mac development and can still be used to

develop applications for PowerPC targets. It continues to support AltiVec hardware accelera-

tion. The commercial market for PowerPC applications is tiny, but PowerPC applications remain

interesting in specialized media and scientific computing.

Create a very simple OS X application using a template as a starting point and adding a text label in IB.

The application runs in its own window and replaces the OS X menu bar (not shown here). Although it

appears to run independently, it is in fact controlled by Xcode and can be debugged while it’s running.
