        Task {
            do {
                let version = try await getAppStoreVersion()
                if version != currentVersion {
                    await MainActor.run {
                        updateAvailable = true
                    }
                }
            } catch {
                print("Version check failed: \(error)")
            }
        }
    }

    private func getAppStoreVersion() async throws -> String {
        // Implement App Store version lookup
        return "1.0.0"
    }
}

In-App Purchase Setup

Release Strategy

Phased Release

  1. 1Phased Release

- 1% for first 2 days - Increase gradually - Monitor crash reports

  1. 1Release Notes

- Highlight new features - Mention bug fixes - Keep it concise

Version Management

swift
struct AppVersion {
    let major: Int
    let minor: Int
    let patch: Int

    var description: String {
        "\(major).\(minor).\(patch)"
    }

    static let current = AppVersion(major: 1, minor: 0, patch: 0)

    func shouldUpdate(to version: AppVersion) -> Bool {
        return version.major > major ||
               (version.major == major && version.minor > minor) ||
               (version.major == major && version.minor == minor && version.patch > patch)
    }
}

Analytics Integration

App Analytics

swift
import AppTrackingTransparency

class AnalyticsManager: ObservableObject {
    func requestTrackingAuthorization() async {
        if #available(iOS 14, *) {
            let status = await ATTrackingManager.requestTrackingAuthorization()

            switch status {
            case .authorized:
                print("Tracking authorized")
            case .denied:
                print("Tracking denied")
            case .notDetermined:
                print("Tracking not determined")
            @unknown default:
                break
            }
        }
    }
}

Beta Testing

Crash Reporting

swift
// Add crash reporting
import Crashlytics

class CrashReportManager {
    func setupCrashReporting() {
        #if DEBUG
        // Disable crash reporting in debug
        #else
        // Initialize crash reporting
        #endif
    }

    func logError(_ error: Error) {
        // Log non-fatal errors
        print("Error logged: \(error)")
    }

    func testCrash() {
        // Test crash reporting
        fatalError("Test crash")
    }
}

Best Practices

  1. 1Testing: Test thoroughly on real devices
  2. 2Beta: Use TestFlight for beta testing
