Canonical Stack for iOS Applications

Create a modularized architecture for scalable native iOS applications. The architecture should support the following requirements:

- Local persistence of data to support offline usage

- Authentication using different providers

- Reactive view updates when state changes

- Layered abstraction of data access and domain logic

- Small dependency footprint

For local data persistence I'm considering to use SharingGRDB, a lightweight replacement for SwiftData and a type-safe query builder for SQLite.

SQLite is embedded into every iOS device.

For the view layer I will use SwiftUI.
