I got this issue once. Here are the steps of what worked for me:-

1. Getting the path for the derived data folder in Finder from Xcode.

2. closing Xcode

3. deleting the derived data folder from finder

4. emptying Trash

5. Reopening Xcode

6. Cleaning and building again.

Hope this helps you as well...
