I just installed XCode 3.2.1. When I open the Developer Documentation and click any link on the startup screen, XCode crashes. Has anyone run into this problem?

I'm in the process of porting a large'ish (~1M LOC) project from a Window/Visual Studio environment to other platforms, the first of which happens to be Mac OS X. Originally the project was configured as Visual Studio solutions and projects, but now I'm using (the excellent) Premake (http://industriousone.com/premake) to generate proje...
In XCode, there doesn't seem to be an obvious way to do this. Visual Studio's debugger provides a keyboard shortcut which sets a temporary breakpoint on the line selected in the code window, runs the debugger to that point, and then removes the breakpoint. In XCode, it seems that you have to manually set and remove the breakpoint to ac...

4 java developers are new to iPod Touch/iPhone app development. They have an idea for an app. They have never used Xcode or Macs before. Instead of spending money for a new iMac or Mac Mini for each of them, my boss would like to sell them a $999 Apple server, hosted at a facility connected a single T1 line, and have all 4 people work...
When editing plist files in Xcode, it can detect the type of plist and show human-readable strings to make it more easy to edit the file. The Info.plist, for example. Thanks to This question, I found the (or a) place where it stores that structure definition, as InfoPlistStructDefs.xcodeplugin. If I put my own file in there, however, ...

Does anybody know how (after edi...
