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

This just worked for me:

• Open your Xcode project.

• Open up a command prompt in your project directory and type:

  touch MyProject.xcodeproj/project.pbxproj

• Watch as syntax coloring and other stuff gets fixed before your eyes.

• Reopen your project (or adjust a project setting) if your project schemes get reset to "My Mac" for iOS projects.
