How To Get Stock Data In Swift

SwiftStock is the simplest way to add real-time Yahoo! Finance stock marketplace information to your Swift app. It's a major Swift upgrade for my previous contribution, MAStockGraph. For simplicity, the example projection (SwiftStockExample.xcworkspace) I built has the Alamofire cocoapod included for networking with the Yahoo Finance APIs. Run pod install every bit usual if information technology complains. Please open bug on the project if you run into snags!

SwiftStock consists of 3 parts-

A predictive stock quote search API.
A comprehensive financial instrument API with all the best data points :D.
A charting API that yields a full set up of time-and-sales data over various time frames (including the elusive intraday 😊)

Requirements

SwiftStock uses Swift 2.ane with ARC and requires iOS 9.0+. It also requires Alamofire be installed.

Installation

Manual

Copy the swift file SwiftStockKit to your project.

Cocoapods

Supported in a later update.

Usage

Quote Search

                              //                Laissez passer in your search term              SwiftStockKit.fetchStocksFromSearchTerm(term: searchText) { (stockInfoArray)              ->              ()              in                              //                And it returns an array of results of blazon                            struct              StockSearchResult              {              var              symbol:              String              ?              var              name:              String              ?              var              exchange:              String              ?              var              assetType:              Cord              ?              }      }

Get a stock from a symbol

                              //                Laissez passer in your symbol                            SwiftStockKit.fetchStockForSymbol(symbol: stockSymbol) { (stock)              ->              ()              in                              //And it returns a stock object that looks like this                            struct              Stock              {              var              ask:              String              ?              var              averageDailyVolume:              String              ?              var              bid:              String              ?              var              bookValue:              String              ?              var              changeNumeric:              String              ?              var              changePercent:              String              ?              var              dayHigh:              String              ?              var              dayLow:              Cord              ?              var              dividendShare:              String              ?              var              dividendYield:              Cord              ?              var              ebitda:              String              ?              var              epsEstimateCurrentYear:              String              ?              var              epsEstimateNextQtr:              String              ?              var              epsEstimateNextYr:              String              ?              var              eps:              Cord              ?              var              fiftydayMovingAverage:              String              ?              var              lastTradeDate:              Cord              ?              var              last:              String              ?              var              lastTradeTime:              String              ?              var              marketCap:              String              ?              var              companyName:              String              ?              var              oneYearTarget:              Cord              ?              var              open:              String              ?              var              pegRatio:              String              ?              var              peRatio:              String              ?              var              previousClose:              String              ?              var              priceBook:              String              ?              var              priceSales:              Cord              ?              var              shortRatio:              String              ?              var              stockExchange:              String              ?              var              symbol:              Cord              ?              var              twoHundreddayMovingAverage:              String              ?              var              volume:              String              ?              var              yearHigh:              String              ?              var              yearLow:              String              ?                              //this has everything neatly packaged to get into a datasource                            var              dataFields: [[String              :              String]] 		}  	}

Charting

                              //                Pass in your symbol and nautical chart time range (enum)              SwiftStockKit.fetchChartPoints(symbol: stockSymbol,              range: range) { (chartPoints)              ->              ()              in                              //                And it returns an array of results of type                            struct              ChartPoint              {              var              date: NSDate?              var              volume:              Int              ?              var              open: CGFloat?              var              close: CGFloat?              var              low: CGFloat?              var              high: CGFloat?              }                              //                Perfect for making candles 😊                            }

In the example I included a quick piddling swift charting library that accepts the assortment of ChartPoint's. Feel gratuitous to use that if you wish as well! (Bonus points for upgrading it with candles back up and opening a pull asking)

To-Exercise

UI Updates to the new styles- Apple keeps changing their listen about they want autolayout to work.
Cocoapods / Carthage Support
Examination coverage and CI with Travis.
Bug bullet-proofing.
