I encountered an issue after setting up a new value for Configuration when building (after reading the following post: Different App Icons for your iOS Beta, Dev, and Release builds). The error message is as follows:
ld: file not found: /Users/.../Library/Developer/Xcode/DerivedData/SomeAppName-.../Build/Products/Debug-iphoneos/SomeAppName.app/SomeAppName
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I'm not sure how to fix it, checked and double checked with the article and I did follow everything as explained.
Edit: The error appears to be from the Tests target
