Mac Catalyst fails to run

[ZComwiz]

Looks like a cool idea @shirakaba! Unfortunately, it has a problem running on MacCatalyst:

 ERROR  Error: ReferenceError: Can't find symbol within this executable: $$typeof
 ERROR  Invariant Violation: Module AppRegistry is not a registered callable module (calling runApplication). A frequent cause of the error is that the application entry file path is incorrect. 
      This can also happen when the JS bundle is corrupt or there is an early initialization error when loading React Native.

Is this just from running the example app as-is?

[ZComwiz]

@shirakaba - I don't think it's possible to run the example project as-is on MacCatalyst on 64.2. In fact, I had to upgrade RN 0.64.0 to 0.64.2 on another project setup in podfile to support catalyst. A fresh project install on 64.0 and adding your library attempts to bundle to macOS when the target is set to mac instead of iOS (iOS bundle is what we want to build a hybrid app with catalyst).
