Building the User Interface

The next step in creating a Lisp version of the currency converter application is to construct the user interface. Apple's tutorial  describes in detail how to do this.

Apple's Tutorial

Apple's tutorial explains how to use InterfaceBuilder to create the user interface, and how to use XCode to create project files and write Objective-C code. Our project uses Lisp instead of Objective-C, and does not use XCode project files, so you can skip the part of Apple's tutorial that explains how to use XCode.
