Error with Turbo Module after adding Swift file

[CaptainJeff]

Description

I'm getting an error with adding my TurboModule if I add a swift file to the module - I have a bridging header and everything and still doesn't work. If i remove the swift file then it works again

Steps to reproduce

1. npx create-react-native-library@latest BleYolanda
2. yarn install && npx pod-install && npx expo run:ios (expo doesn't use prebuild. I manage the android and ios directories). Note everything works here
3. in modules/demo-turbo-module/ios add ble-yolanda-Bridging-Header.h and BleYolanda.swift and run all of the commands again and I get the following errors

I've tried just about everything... I can see in xcode that RNBleYolandaSpec/RNBleYolandaSpec.h does exist and links to it properly, etc..
