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)
}
