Create a new scheme. The bundle id / target name / executable / project name etc. are all slightly different concepts. If you change one (as I did) the old scheme may still be set to look for the old value as the name of the executable, while the build process may have been updated to no longer build that executable.

The answer lies on your Build Settings > Library Search Paths entry. Make sure there are no fully qualified paths listed there. Decorate them with the $SRCROOT idiom and enclose the path with double quotes. If there are any escape backslashes make sure to remove them as well.

Do a Clean and then Build and you should be back in business. This seem to be an issue with Xcode 5.x

Answer 5

On xcode 6 you need to:

1. go to products folder
2. click on file .xctext
3. on "TARGETS" choose Tests
4. and on Host Application choose your application.
5. Click build app.

Works for me!

Answer 6

Delete your scheme then re-create it (click new icon or using autocreate of xcode). It works for me.
