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

In my XCode 4 setup, it is 100% reproducible that setting the User Header Search Path will break codesense, especially "Jump to Definition", after a restart. I have create a new project, added my helper library as a subproject. If I include the headers with the User Header Search Path (recursive), I can compile, but autocomplete/navigation is broken.

Deleting the header search path, closing the project, and reopening, fixes it again.
