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' folder in Xcode there are 2 files:

MyApp.app MyAppTests.octest [which appears red]

Update: Deleted all the build folders (derived data) still doesn't work!

Answer 1

The following solution works for me:

-> Select your project

-> Select your projectTest file from TARGETS

-> In Host Application, select your project if it shows custom

Answer 2

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 3

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...
