Architecture

• MVVM, see templates folder
• Model consists of small Repositories
• Model is shared across modules using EnvironmentObject
• Repositories use network Services or CoreData
• Repositories are injected to ViewModels
• ViewModels are injected to Views as @StateObject
• Each Repository holds LoadingStates(idle, data, error) for it's data and state
• View and ViewModel can delegate routing to Router if there are many routes from a View
• Errors are passed using a LoadingState and displayed using errorPopup ViewModifier (see ErrorHandling.md)
