iOS test project that retrieves BTC rates from CoinDesk API and displays it on an iOS app and a Watch companion. Project also includes a TodayExtension.
The project has been made using VIPER architecture. The file RatesProtocols.swift contains a general overview of the different entities and how they interact with each other.
For the interactors I have decided to split them for Local (Cache) and Remote (CoinDesk API).
For the WatchExtension I have use the same module replacing the ViewInterface for one for Watch, however, in a more complex UI a new presenter would be necessary.
For the TodayExtension the RemoteInteractor is used independently from the ViewController. This is not ideal.
NOTE: I had no previous experience with WatchKit apps nor Today Extension so forgive for any bad practices I may have taken.
-
RequestManager is a simple library to create HTTP requests without much overhead. See: https://github.com/gzafra/SimpleRequestManager
-
For the project structure I have decided to split it in 3 layers (presentation, domain, data) and within these, for the specific modules and one for common / shared content.
-
For the UI I have decided to use programmatically created views as UI is simple and it allows for easier testing.
There are several TODO's in the project about things that should be reworked next.
-
Refactor UI to adapt to different devices (especially the Watch)
-
Move hardcoded config values (URL's, Endpoints) to config plist file.
-
Workout failure cases, retries and recovery.
