React native support for SPM is non-existent for the most part. There's some work on porting to SPM but it's gonna be a while before anything becomes stable. It's going to break a huge amount of 3rd party packages. A bit of shame this wasn't done earlier as the RN ecosystem just went (or, is still going) through a migration to the "new architecture" that required most 3rd party packages that use native code to be "ported" over. Could have been a two-for-one kinda thing!
React-Native is blocked by SwiftPM not supporting mixed ObjC and Swift packages. It needs that to support both the Old Architecture and the New Architecture at the same time.
