Hi, I have little effort to answer your question.
To create a watchOS app, start by adding a watchOS target to the project. Xcode adds groups and files for the watchOS app to your project, along with the schemes needed to build and run the app. For more detail also see https://forum.ionicframework.com/t/integrating-an-apple-watch-app-into-an-10eloto-ionic-project/222351
Thanks
