Current Behavior

I integrate over 10 in-house capacitor plugins into my iOS native app. These plugins are managed within a designated folder named 'Capacitor Plugins' (.m / .swift files) and seamlessly bridged with my Ionic/Angular hybrid app

In my Ionic app, I utilize these plugins to retrieve data from the native iOS app. However, after upgrading from Capacitor 5 to 6, all these plugins are now showing as 'unimplemented.'

Expected Behavior

Plugins should work the same as they did using capacitor 5.7.5

Project Reproduction

Additional Information

App should display the following prompt under capacitor 5 and 6 using the apprater plugin. Instead the demo project reports

⚡️ WebView loaded ⚡️ To Native -> App addListener 54677256 ⚡️ To Native -> Keyboard getResizeMode 54677257 ⚡️ TO JS {"mode":"native"} ⚡️ [error] - ERROR {"code":"UNIMPLEMENTED"}

Capacitor 6 removes automatic plugin registration on iOS, for NPM plugins we can get the classes and register them programmatically, but for custom code you have to call register yourself, see https://capacitorjs.com/docs/ios/custom-code#register-the-plugin
