SwiftStockEarnings

A Swift package for fetching and parsing stock earnings data from the web.

• Fetch earnings data for any stock symbol
• Parse next earnings date
• Determine market timing (Before Market, After Market)
• Get projected earnings window
• Built-in network client with default implementation

Add the following to your Package.swift file:

dependencies: [
    .package(url: "https://github.com/yourusername/SwiftStockEarnings.git", from: "0.1.0")
]

Or add it directly in Xcode by going to File > Add Packages and entering the repository URL.

import SwiftStockEarnings

// Create an instance
let earnings = SwiftStockEarnings()

// Fetch earnings data for a stock symbol
Task {
    let earningsData = await earnings.fetchEarningsData(for: "AAPL")
    
    // Access the data
    if let nextEarningsDate = earningsData.date {
        print("Next earnings date: \(nextEarningsDate)")
    }
    
    switch earningsData.marketTiming {
    case .beforeMarket:
        print("Earnings will be released before market open")
    case .afterMarket:
        print("Earnings will be released after market close")
    case .unknown:
        print("Market timing is unknown")
    }
    
    if let windowStart = earningsData.projectedEarningsWindowStart,
       let windowEnd = earningsData.projectedEarningsWindowEnd {
        print("Projected earnings window: \(windowStart) to \(windowEnd)")
    }

    if earningsData.isConfirmed {
        print("Earnings date is confirmed")
    } else {
        print("Earnings date is not confirmed")
    }
}

You can provide your own network client implementation by conforming to the EarningsNetworkClient protocol:

let customClient = YourCustomNetworkClient()
let earnings = SwiftStockEarnings(networkClient: customClient)

The package returns an EarningsData struct containing:

• date: The next earnings date (optional)
• marketTiming: When the earnings will be released (before market, after market, or unknown)
• projectedEarningsWindowStart: Start of the projected earnings window (optional)
• projectedEarningsWindowEnd: End of the projected earnings window (optional)
• isConfirmed: Boolean indicating whether the earnings date is confirmed (the logic behind this: if both earnings-window are present, then the earnings date is not confirmed)

The package handles errors gracefully by returning an empty EarningsData struct if any errors occur during fetching or parsing.

• iOS 13.0+ / macOS 10.15+ / tvOS 13.0+ / watchOS 6.0+
• Swift 5.5+
