More investigation today on the following block of code:

Two issues:

1. Missing defaultAction in map leads to not linked failure:

   (lldb) po action 
   FirebaseAuth.AuthRecaptchaAction.defaultAction
   (lldb) po actionToStringMap 
   ▿ 3 elements
   ▿ 0 : 2 elements
   - key : FirebaseAuth.AuthRecaptchaAction.signUpPassword
   - value : "signUpPassword"
   ▿ 1 : 2 elements
   - key : FirebaseAuth.AuthRecaptchaAction.signInWithPassword
   - value : "signInWithPassword"
   ▿ 2 : 2 elements
   - key : FirebaseAuth.AuthRecaptchaAction.getOobCode
   - value : "getOobCode"

2. Fails to do reflection:

   po NSClassFromString("RecaptchaAction")  as? any RCAActionProtocol.Type
   nil

Why does this cast fail?
