iPhone Dev 101: Creating Xcode projects, brief Xcode UI overview


In our last iPhone Dev 101, a continuing series on iPhone development, we talked about resources that you can use while you are coding with Cocoa. In this dev post, I'm going to walk you through Xcode and creating your first project.

First we need to open Xcode, so once you have the SDK installed, you'll need to open /Developer/Applications/ and look for Xcode.app. This is Apple's IDE (Integrated Development Environment) that allows you to code, debug, test, and build all of your iPhone and Mac applications. When you open this application, nothing specially really happens, although you might see the welcome center -- if you see this, you can choose to disable it at startup by using the check box at the bottom.

To create a new project, select File > New Project. In the resulting window select iPhone OS Application > View-based Application, and click "Choose." You will then need to specify a save name and location for the resulting files that will combine to create your application. In the resulting Xcode window, you should note that most of the work is already done for you!

At this point you have a fully functional application. Try it out: click the "build and go" button at the top of the window and wait while the app is compiled and opens in the iPhone Simulator. The app definitely doesn't do much, but still, it's a running application you made without writing any code.

Video of a MacBook Pro stomping a PowerMac G5 compiling Java

What's a big news day without a little bit of a hardware smack down? Call me crazy, but I just found this Gear Live site through diggdot.us, and these guys posted a video podcast in a variety of formats of a MacBook Pro with a (comparatively) measly 1 GB RAM making mince meat out of a Dual 2.0 GHz PowerMac G5 with 4 GB RAM in a Java compile test.

While it isn't a comprehensive rundown of a variety of tasks and apps these two systems can run, it's still pretty impressive to see how well this next generation hardware can perform.
