Unit tests failing to run after app rename due to apple linker error

Question

I recently changed the name of my app and now my unit tests are not running, I am getting an Apple linker error.

Any idea how to fix this? If I expand my \'Products

Answer 1

For the current version of Xcode, you just need to click on the project, then change the name in the file inspector. Or you can right-click on project, and there will be a "Renaming a project" in the help dialog.

The following solution works for me:

-> Select your project

-> select your projectTest file from TARGET

-> In Host Application, select your project from dropdown only if it show custom

I don't know if this would help you solve your problem but you could try going to the organizer and under Projects tab hit remove for all Derived Data

Answer 5

In my case, I had the similar issue after performing app rename. I'm running Xcode 8.x and what I did was:

1) Project -> Targets -> xxTests -> General -> Enable 'Allow testing Host Application APIs'.

2) Perform clean & rebuild

3) In [Simulator], reset it: Simulator -> Reset Content and Settings...

I faced similar issues when renaming my app. You should try with a fresh clean build. Make sure that you remove all build folders (performing a clean in XCode sometimes is not enough).
