Analytics & Crash Reporting

Xcode Organizer

After release, use Xcode Organizer to view crash logs, energy reports, and performance metrics from users.

---

Integrate Analytics SDKs

Add third-party analytics and crash reporting SDKs via SPM or CocoaPods.

Follow privacy best practices and disclose data collection.

Example

Package.swift (snippet)

App.swift

// Example: Add an analytics package
// .package(url: "https://github.com/acme/analytics-sdk", from: "1.0.0")

Add the analytics package to your project by specifying the URL and version.

---

Logging (os.Logger)

Use structured logging for diagnostics and to correlate user issues.

Example

Logger.swift

import os

let logger = Logger(subsystem: "com.example.app", category: "network")

func fetch() async {
  logger.info("Starting fetch...")
  do {
// ... network call ...
logger.debug("Response status: \(200)")
  } catch {
logger.error("Fetch failed: \(error.localizedDescription)")
  }
}

---

Track Events (with Consent)

Design a minimal event tracker and send only necessary, non-PII data. Gate collection on user consent.

Example

Events.swift

import Foundation

struct Event: Codable {
  let name: String
  let props: [String: String]
}

class EventTracker {
  var consentGiven = false
  func identify(userId: String?) { /* store hashed or anonymous ID */ }
  func track(_ event: Event) {
guard consentGiven else { return }
// enqueue and batch to your endpoint
  }
}

---

Privacy

• Honor user consent; provide opt-out where applicable.
• Minimize PII; prefer anonymized, aggregated events.
• Update your App Privacy Listing if data collection changes.

Tip: Correlate crash reports with app versions and feature flags to speed up incident response.

Automate symbolication for reliable stack traces.

---

Crash Reporting Options

• Xcode Organizer: Built-in crash log collection and metrics for App Store builds.
• Third-party SDKs: Firebase Crashlytics, Sentry, etc. for real-time alerts, user/session context.
• Symbolication & dSYMs: Ensure dSYMs are uploaded so stack traces resolve to your source lines.

dSYMs: If using a crash SDK, configure automatic dSYM upload (e.g., Run Script Phase or CI) to avoid unsymbolicated crashes.

---

Performance Metrics

Add lightweight timing via signposts and analyze in Instruments.

Example

Signposts.swift

import os

let signposter = OSSignposter()

func loadFeed() async {
  let id = signposter.makeSignpostID()
  let state = signposter.beginInterval("load_feed", id: id)
  // ... perform work ...
  signposter.endInterval("load_feed", state)
}
