Making the move to the Mac

Part Two
Last time round, we cautiously dipped a toe into the Mac development waters from the perspective of a Windows programmer with RAD experience. Along the way, I briefly looked at the rudiments of Objective-C syntax, and I described terms such as 'framework' and 'Cocoa'. (Remember, the idea here is not to turn you into a killer Mac coder, but rather to look at the essentials of mainstream Mac development using terminology that's familiar to a .NET, Delphi, C++ or VB developer.)
With this as a basis, let's turn our attention to Xcode and Interface Builder. These are the two main development tools used by a Cocoa developer. (As I said last time, it's perfectly possible to create Cocoa apps using only command-line tools. It's not nice, but if you're that way inclined...)
