FR: Add watchOS support

[Shivamdhuria]

It'll be really cool If I could add a watchOS target to the already existing ios app. If I add a target through Xcode, it is unable to access the "shared" files and I get this error "Building for watchOS Simulator, but the linked framework 'shared.framework' was built for iOS Simulator. kotlin project"
I couldn't find a lot of resources on this so I think this could be a nice addition to this project.
