        I have a project where I am using Firebase's Firestore and Auth. When I create a SwiftUI view, the preview canvas doesn't work. I get the following error.

        Compiling failed: linker command failed with exit code 1 (use -v to see invocation)
        failedToBuildDylib: ld: warning: directory not found for option '-F/Applications/Xcode.app/Contents/SharedFrameworks-iphonesimulator'
        Undefined symbols for architecture x86_64:
          "___asan_alloca_poison", referenced from:
          +[GDTFLLUploader gzippedData:] in GoogleDataTransportCCTSupport(GDTFLLUploader.o)
          "___asan_allocas_unpoison", referenced from:
          +[GDTFLLUploader gzippedData:] in GoogleDataTransportCCTSupport(GDTFLLUploader.o)
          "___asan_handle_no_return", referenced from:
          -[FIRAuthCredential init] in FirebaseAuth(FIRAuthCredential.o)
          -[FIRAuthCredential prepareVerifyAssertionRequest:] in FirebaseAuth(FIRAuthCredential.o)
          -[FIREmailAuthProvider init] in FirebaseAuth(FIREmailAuthProvider.o)
          -[FIRCollectionReference initWithQuery:] in FirebaseFirestore(FIRCollectionReference.o)

        This happens even with the most basic "Hello World" View, where I don't import anything related to Firebase.

        Is there anything I can do about this, or can I simply not use the preview canvas in this entire project?
