How to Set Up Session Replay in Swift

Overview

Bug reports saying 'it doesn't work' are useless without context. Session replay for Swift shows you exactly what the user did, saw, and experienced.

Bugsly provides a first-class Swift integration for session replay that takes minutes to set up and immediately starts delivering value.

Installation and Setup

Start by adding Bugsly to your project:

pod 'Bugsly'

Next, initialize the SDK in your application:

import Bugsly

func application(_ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    BugslySDK.start { options in
        options.dsn = "YOUR_BUGSLY_DSN"
        options.tracesSampleRate = 1.0
    }
    return true
}

How It Works

Once initialized, the Bugsly Swift SDK automatically instruments your application. Here's what happens behind the scenes:

• Automatic error capture: Unhandled exceptions and promise rejections are caught and reported with full stack traces
• Context enrichment: Each event includes environment data, request details, and user context where available
• Intelligent grouping: Similar errors are grouped together so you see issues, not individual events
• Performance data: Transaction traces help you understand the performance impact of errors

Customizing Your Integration

For Swift projects, we recommend enabling these additional features after the basic setup:

1. Source maps (if applicable) — upload source maps during your build so Bugsly can display readable stack traces
2. User feedback — prompt users who encounter errors for additional context
3. Custom tags — add business-specific metadata to events for filtering and analysis

Bugsly's dashboard will become your team's go-to tool for understanding what's happening in your Swift production environment.
