Swift Notes is a simple note management app written in Swift.
This app uses MVVM-C with services as a core architectural pattern. Dependencies include RxSwift, RxDataSources, Moya, Swinject, Quick/Nimble, Realm, SwiftLint, Swiftgen, SpecLeaks...
To keep things simple, this app uses a Realm layer to cache the last known list of notes. Other functionality (CUD) requires an internet connection.
In order to solve issues with notes being concurrently edited on different devices with a different cache state, this app implements a simple CAS versioning scheme. Since the backend doesn't support CAS version numbers, we're emulating them client-side using a hash of the note title.
I've implemented my own API to persist notes; code to handle the mock API can be found at the bottom of NotesProvider (commented out).
The app uses RxDataSources to populate the table view with notes. A delay is added to async operations to showcase loading dialogs.
The following tests are implemented:
- VC unit tests
- VM unit tests
- Service mocks
- Service tests
- Basic VC leak tests (init & viewDidLoad). I actually caught one memory leak in
NotesDetailViewController- a forgotten[weak self]in aonNextclosure. Useful! - A basic UI test
- Assets - xcassets, fonts, colors...
- Flows - coordinator flows, in this case only Notes
- Models - note models and related services
- Utility - utility classes
