Answer 1

I had this same error for a couple of weeks:

dyld: Library not loaded: @rpath/libswiftContacts.dylib

Basically I was able to run and test my app on device. Then about 2 weeks ago, I wasn't able to run the tests on device anymore. Tests were running fine on simulator. I can't think what changed. The error I saw was the one above. I searched Google for ages trying to find a solution, and tried many fixes unsuccessfully. The fix that finally worked was to delete the Derived Data. Once I did this, I was once again able to run the tests on my device.

Fix that worked for me:

1. Go to Xcode > Preferences > Locations > Derived Data (click on little arrow to open up the folder in finder) e.g. /Users/[username]/Library/Developer/Xcode/DerivedData

2. Delete the entire DerivedData folder

3. Clean/Build

4. Test on device - finally works again
