Xcode 4: Auto-complete & Jump to Definition broken in my Xcode 3 Project

Question

My project was created in Xcode 3, I\'m opening it in Xcode 4 and notice the following:

• \'Jump to Definition\' no longer works with my own symbols

Answer 1

I had the same problem in XCode 4 final version today, working with my old XCode 3 project. The problem is related to an index of symbols that XCode creates. It should create a new index for you automatically, but it seems to take a long time in XCode 4. One possible solution is to go to ~/Library/Developer/Xcode/DerivedData and delete the old index. Restart XCode, and you should see it indexing. For 'Jump to Definition', you can hold down command and mouse over a method or class name, and you should see blue underlines, like hyperlinks. Then you can click on it to jump to definition.
