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

In my case I solved in this way.

• Go to Project's propreties from Project navigator.
• Build Phases
• Add your *.m files in "Compile Sources"

Now re-build.

This could be happen, for instance, when your manually rename a class after its creations.

Hope this help.

Answer 2

For others if none of the above mentioned methods worked try this :

Go to menu bar Xcode - > Preferences -> Locations -> Command Line Tools

Choose proper (current) Xcode format here.

Answer 3

Xcode 10.2.1 - simply closing Xcode entirely and reopening it solved it for me.

Answer 4

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

Answer 5

3 reasons this happens :

1. Corrupt derived data : Solution : clean derived data folder.

2. Corrupt project settings : Project.xcodeproject -> Right Click and clean the files mentioned in g_low's answer.

3. File not a part of project target : Check if the file is a part of compile source and if not add it...

Answer 6

I had this problem, restarted, quit Xcode, nothing happened. Switched to master branch, pulled, checkout into new branch. Problem Gone. I even went back to my previous branch and all was working. My only guess is that git messes up sometimes!
