'ld: file not found' after changing produc

Question

I was working on my application and i started out with a really bad name. So i decided to change it. I did that like this.

At the top right corner i simply changed the name to what i want. and then i started getting the error as you can see there. Reveal in Log shows these details:

The main error says:

ld: file not found: /Users/.../XCode/DerivedData/...

Answer 1

Go to edit scheme as shown below.

then uncheck all other targets except your main target under build tab.

Answer 2

I resolved this by Deleting the Derived Data and rebuilding the project.

1. Go to Windows > Projects
2. Select Your Project
3. Delete Derived Data
4. Build your project and Run

Answer 3

If you see this error without detail result then check 'enum' in header file. Move them in .m file.

Answer 4

By deleting the derived data Xcode will recompile and regenerate the data for you.

You can do that by going to: Windows -> projects Delete derived data

Answer 5

I recently got this error under different circumstances. Running Ionic, updating my ios platform from 3.8.0 to 4.0.1 I discovered this error.

I had to disable bitcode in my app.

To do this, click your top level app icon in the file structure. In the main window, click the header build settings. In the search bar, type bit (or bitcode) and you should see enable bit code beneath

I had disabled it before, but I'm guessing that updating the ios platform enables bitcode so it needed to be disabled again.

Answer 6

No need to mess with schemes. Just go to build settings for your targets or project and turn off Bitcode.
