I've been asked to debug a prototype iPad app (written in Objective C). I thought a good approach would be to write a series of unit tests (IDing bugs and helping me familiarise myself with the code). Though I have written unit tests before I've never used xcode, Objective C; or a Mac for that matter.
The problem being that the code as it stands won't currently build - there are a large number of errors. I'm wondering if there is a way to unit test certain parts of the code using xcode without having to build the entire project; or do I need to ID what's causing all or the errors and eliminate these first?
