问题
I'm running Xcode 11 Beta 4. I'm using CocoaPods, and wanted to use one of my dependencies with Swift Package Manager as a static library instead of as a framework. On a fresh project created with Xcode 11, the dependency can be imported successfully, but on my existing CocoaPods workspace, it does not.
I think it's likely related, but I'm also getting this link warning in Xcode:
directory not found for option '-L/Users/username/Library/Developer/Xcode/DerivedData/App-axanznliwntexmdfdskitsxlfypz/Build/Products/Release-iphoneos
I went to see if the directory exists after the warning is emitted, and it does. I could not find any meaningful difference between the newly-created project and my old one, other than the existence of CocoaPods.
Would appreciate any pointers.

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}/"
fi

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.

After a whole week fighting this issue, I developed a workaround using schemes and pre-actions.
I have a configuration called "Beta", so Xcode can't compile SPM dependencies. I realised Xcode compile SPM dependencies as Swift modules and add the files in Build/Products/Release-iphoneos folder in DeriverData.
So I created a scheme in Xcode and added this run script on build pre-actions:
cp -f -R "${SYMROOT}/Release${EFFECTIVE_PLATFORM_NAME}/" "${SYMROOT}/${CONFIGURATION}${EFFECTIVE_PLATFORM_NAME}/"
This script run before the build process, coping files and modules generated by Xcode on default Release-iphoneos folder to configuration folder, Beta-iphoneos, in my case.
After coping the content from Release-iphoneos to your $configuration$-iphoneos folder Xcode should correctly compile, build and run your project.

In order to keep incremental builds working I had to specify the output files of "Fix SPM" build phase like so:
