问题:

Can I connect to a remote Realm without having to login?

In Swift, the only way to create a synchronizable Realm is through the syncConfiguration property of a Realm.Configuration. Is there a method for getting an anonymous User so that anyone can connect to the remote Realm?

No, you always need to be authenticated.

Yes, via SyncCredentials.anonymous().

This is now possible in Realm Cloud. Here's how I am doing it in Swift:

if let user = SyncUser.current {
  //--== User available ==--
  let config = Realm.Configuration(syncConfiguration: SyncConfiguration(user: user, realmURL: "..."))

  Realm.Configuration.defaultConfiguration = config
  let _ = try! Realm()

}else{
  //--== No User; Connect Anonymously ==--
  let credentials = SyncCredentials.anonymous()

  SyncUser.logIn(with: credentials, server: "...") { user, error in
    DispatchQueue.main.async {
      if let user = user {
        let config = Realm.Configuration(syncConfiguration: SyncConfiguration(user: user, realmURL: "..."))
        Realm.Configuration.defaultConfiguration = config
        let _ = try! Realm()

        }else{
          //Error...
        }
      }
    }
  }
}

Good luck!
