CryptoApp (SwiftUI)

This project is following the great and free course SwiftUI Crypto App by @SwiftfulThinking. I can not thank him enought for such a great course.

We are using Core Data, SwiftUI, Combine and others great tools. I added new features covering and using Clean Architecture, Mappers, Localization, SwiftLint and Unit Tests.

Structure

The project has the following structure:

utilities extensions services data remote mappers models core components Launch Views Home ViewModels View Detail ViewModels View Settings ViewModels Views Resources JsonResponse

API Reference CoinGecko

Using Free CoinGecko API for this project. The free plan has a limitations:

The rate limit is ~30 calls per minutes and it varies depending on the traffic size.

So sometimes to avoid this and be able to use the preview I stored the JSON response of the API calls so I can test the service calls like a fake response, and then only use the real API call when I build the app.

    URL BASE: https://api.coingecko.com/api/v3/

Get Coins Data

    GET coins/markets?vs_currency=usd&order-market_cap_desc&per_page=100&page=1&sparkline=true&price_change_percentage=24h

Get Coin Detail

    GET coins/{coinId}?localization=false&tickers=false&market_data=false&community_data=false&developer_data=false&sparkline=false

Get Market Data

    GET global

Service	JSON Response File
Get Coins Data	marketsResponse.json
Get Coin Detail	bitcoinDetailResponse.json
Get Coin Detail	marketDataResponse.json

If we exceed the rate limite, we can do like this in CoinDetailDataService:

Comment the line with dowlonad function:

// coinDetailsSubscription = networkingManager.download(url: url)

And uncomment the next like using the json file:

 coinDetailsSubscription = networkingManager.readLocalJSON(nameFile: "bitcoinDetailResponse")
