My name is Ian Beck. I'm Director of Web Services at Tierra Interactive. Here are things I find useful or interesting.

Tip: When compiling an external framework like JSCocoa for inclusion in a bundle, make sure to change the Installation Directory in the framework’s target to @loader_path/../Frameworks. This causes Objective-C to look for the framework in your bundle path instead of the application path or the standard framework locations.

(If you are working on a full application instead of a bundle, you can use @executable_path/../Frameworks instead.)
