When adding a cocoapods dependency, we started getting build errors like these:
Undefined symbols for architecture x86_64:"type metadata accessor for (extension in Foundation):__C.NSURLSession.DataTaskPublisher", referenced from: (extension in TinyNetworkingObjcIO):__C.NSURLSession.load<A>(TinyNetworkingObjcIO.Endpoint<A>) -> Combine.AnyPublisher<A, Swift.Error> in libTinyNetworkingObjcIO.a(Endpoint.o) lazy protocol witness table accessor for type (extension in Foundation):__C.NSURLSession.DataTaskPublisher and conformance (extension in Foundation):__C.NSURLSession.DataTaskPublisher : Combine.Publisher in Foundation in libTinyNetworkingObjcIO.a(Endpoint.o)"protocol conformance descriptor for (extension in Foundation):__C.NSURLSession.DataTaskPublisher : Combine.Publisher in Foundation", referenced from: lazy protocol witness table accessor for type (extension in Foundation):__C.NSURLSession.DataTaskPublisher and conformance (extension in Foundation):__C.NSURLSession.DataTaskPublisher : Combine.Publisher in Foundation in libTinyNetworkingObjcIO.a(Endpoint.o)"(extension in Foundation):__C.NSURLSession.dataTaskPublisher(for: Foundation.URLRequest) -> (extension in Foundation):__C.NSURLSession.DataTaskPublisher", referenced from: (extension in TinyNetworkingObjcIO):__C.NSURLSession.load<A>(TinyNetworkingObjcIO.Endpoint<A>) -> Combine.AnyPublisher<A, Swift.Error> in libTinyNetworkingObjcIO.a(Endpoint.o)ld: symbol(s) not found for architecture x86_64clang: error: linker command failed with exit code 1 (use -v to see invocation)These errors just appear kind of "out of the blue" after we added a new dependency to our Podfile, with no info about what caused them and what part of the code it originates from, they're just printed after the build and during the linking stage, which now fails.
What does this error mean? What can be done to try and resolve it?
This happens to be a react-native generated XCode project, not sure if that's relevant.
