Link error /Build/Products/Debug-iphonesimulator file not found

Question

I have problem with Xcode, keeps giving me a linker error, and it doesn't build the project. The following is the error am getting

ld: file not found: /Users/someuser/Library/Developer/Xcode/DerivedData/MAR-akbwbarcniqxytctbebckkelkbxs/Build/Products/Debug-iphonesimulator/MAR.app/MAR

clang: error: linker command failed with exit code 1 (use -v to see invocation)

Answer 1

As some of the fellow developers have mentioned here, the root cause of the error was "Change in Product Name". I fixed it by :

1. Go to [project]Tests -> general

2. Select Host Application

Answer 2

I picked up a project that had this same error. I found that the project name had changed, but the code I had did not reflect that change in the project build settings. To correct, I updated the "Product Name" value (found under targets | Packaging) to the correct value and rebuilt the project. Ran fine.
