// This gist demonstrates how ObservableObjects can be composed in a simple way by leveraging a new
// @Republished property wrapper. @Republished republishes child state objectWillChange messages on its 
// parent's objectWillChange publisher, tying the two together.

// The example app is from PointFree Co's episode: https://www.pointfree.co/episodes/ep146-derived-behavior-the-problem

// The one major change besides @Republished is that the "favorites" state has been extracted from the 
// Counter/ProfileViewModels into a single source of truth: FavoritesViewModel.

1. Create a Production.xcconfig and a Development.xcconfig file (or whatever you want to call them)
2. In both of those config files: (production) [development]

BUNDLE_IDENTIFIER = (com.company.ios) [com.company.ios.dev]
PRODUCT_NAME = (App) [App Dev]
API_SCHEME = (https) [https]
API_HOST = (api.company.com) [dev.company.com]

3. In the Project Navigator select the Project (not a Target) > Info > Configurations > + “Duplicate Debug” > Rename to “Development Debug”
4. Rename “Debug” -> “Production Debug”, “Release” -> “Production Release”
