0.76: undefined function when using a swift App Delegate (iOS)

[fbp93]

Description

Since RN 0.76 many packages that use iOS native code started to break at runtime with the error <function> is not a function (it is undefined). For example using [this localization package ](https://github.com/zoontek/react-native-localize) I get _NativeRNLocalize.default.getTimeZone is not a function (it is undefined)`.
I tried on a sample project and everything seems working fine if I use the objective c AppDelegate, but break when I use a Swift AppDelegate.
Everything was working fine up to 0.75.x, even if the swift AppDelegate.
Am I missing something during the swift setup with the new architecture?

Steps to reproduce

1. Install the app
2. See the runtime error
