Getting 'no such module' error when importing a Swift Package Manager dependency

After adding a library (FASwiftUI in my case) through Swift Package Manager I had to add it to

Project Settings -> My Target -> General -> Frameworks, Libraries, and Embedded Content

to be visible in the import statement.

I did not add any scripts for it to work.

It turned out that Swift Package Manager implicitly depends on the project's Configuration names. I had them at live/qa instead of Release/Debug, and changing them back resolved the issue. Very odd, but I hope it saves you some trouble dear reader.

Based on @AlexandreMorgado answer it seems like it is better to run this script in Build phases before Compile Sources. Then it works when archiving.

if [ -d "${SYMROOT}/Release${EFFECTIVE_PLATFORM_NAME}/" ] && [ "${SYMROOT}/Release${EFFECTIVE_PLATFORM_NAME}/" != "${SYMROOT}/${CONFIGURATION}${EFFECTIVE_PLATFORM_NAME}/" ] 
then
  cp -f -R "${SYMROOT}/Release${EFFECTIVE_PLATFORM_NAME}/" "${SYMROOT}/${CONFIGURATION}${EFFECTIVE_PLATFORM_NAME}/"
