Xcode code sense and cmd+click to symbol doesn't work for 1 of my projects

Question

I\'ve been using Xcode 4.3.1 since it came out now and i\'ve worked on many different projects since. Everything has always worked fine until this 1 new project i\'m working

Answer 1

With Xcode 8.2 I solved in this way:

1. File > Workspace Settings
2. Click over the little grey arrow above Advanced... Button (Derived Data)
3. Select my project folder and delete it.

Now in your project see if cmd+click works
