I fixed similar error in my iOS app by removing "\"$(TOOLCHAIN_DIR)/usr/lib/swift-5.0/$(PLATFORM_NAME)\"", line from LIBRARY_SEARCH_PATHS in project.pbxproj file.

I ran in to a similar issue when trying to create a home screen widget in Xcode 12 for iOS 14. The fix mentioned above didn’t work for me, but it set me on the right path. I’m posting my fix here in case others may find it useful!

For me, there were two steps to fixing this issue:

Removed all entries from LIBRARY_SEARCH_PATHS in the Project configuration
Add a new Swift file to the project (File > New > File > Swift), and call it whatever you want

Thanks @iyegoroff - this did the trick for me.

I had to delete this from both the watchapp & watchapp extension targets.

This seems to only fix the issue while in Debug scheme. Once I try to build the app in the Release scheme, I still get the same error. This happened to me when I added the @stripe/stripe-react-native package. Anyone else got that issue in Release, please advise. Thanks in advance.

that is on “Debug” or “Release” because on Library Search Paths has two drop down ? I am not seem those line available , could you give the more detail about it ? I face the issue on RN 0.64

Same here. Can someone provide more information?
