I made my first Cocoa app today. Instead of the ubiquitous "Hello World!" application that most books make you create, Cocoa Programming for Mac OS X actually has you create a graphical random number generator. Since this is the first time I'm doing any Mac OS or NextStep programming, it was a bit interesting to see how things work. Xcode and Interface Builder are nice, but it's a bit strange to do interface building and coding in separate apps. Having spent most of the time doing .NET/Java development, it's a nice breath of fresh air to try something new out.
