6. Integration with backend services for end-to-end visibility

With these capabilities, the OneAgent SDK offers a comprehensive toolkit for iOS developers to ensure their apps perform at their best.

Getting Started with Dynatrace iOS SDK

Integration Process

Integrating the Dynatrace iOS SDK into your iOS app is a straightforward process. Here’s a step-by-step guide:

1. Create a mobile application in the Dynatrace web UI
2. Choose an integration method:
   • CocoaPods
   • Swift Package Manager
   • Carthage
   • Manual integration
3. Configure the OneAgent SDK in your app’s Info.plist file
4. Start the OneAgent in your app’s lifecycle

Let’s break down each step in more detail:

1. Create a Mobile Application in Dynatrace

Before integrating the SDK, you need to create a mobile application in the Dynatrace web UI. This process will provide you with the necessary configuration details, such as the application ID and beacon URL.

2. Choose an Integration Method

Dynatrace offers multiple ways to integrate the OneAgent SDK into your iOS app:

• CocoaPods: Add the Dynatrace CocoaPod to your Podfile and run pod install.
• Swift Package Manager: In Xcode, go to File > Swift Packages > Add Package Dependency and use the URL https://github.com/Dynatrace/swift-mobile-sdk.git.
• Carthage: Add github “Dynatrace/swift-mobile-sdk” to your Cartfile and run carthage update.
• Manual: Download the OneAgent SDK for iOS from the Dynatrace UI and manually integrate it into your Xcode project.

3. Configure the OneAgent SDK

Add the required configuration keys to your app’s Info.plist file:

• DTXApplicationID: The application ID from the Dynatrace UI
• DTXBeaconURL: The beacon URL from the Dynatrace UI

You can also customize the OneAgent SDK configuration by setting additional keys in the Info.plist or passing a configuration dictionary when starting the agent.

4. Start the OneAgent

Start the OneAgent as early as possible in your app’s lifecycle, typically in the applicationWillFinishLaunching method:

swift

Copy

Dynatrace.startupWithInfoPlistSettings()

Or, if you prefer to use a configuration dictionary:

swift

Copy

let config = [

    “DTXApplicationID”: “your-app-id”,

    “DTXBeaconURL”: “your-beacon-url”

]

Dynatrace.startupWithConfig(config)

Best Practices for Configuring OneAgent SDK

To get the most out of the Dynatrace OneAgent SDK, consider these best practices:

1. Optimize Instrumentation

• Use package managers like CocoaPods or Swift Package Manager for easier setup.
• Add application identification keys to the Info.plist file as per Dynatrace documentation.
• Trigger a project build before using the OneAgent SDK or any import declarations in Xcode.

2. Customize Instrumentation

• Enable or disable automatic web request instrumentation based on your app’s needs.
• Manually instrument non-HTTP(S) requests like WebSocket or gRPC.
• Leverage custom actions to report additional details about user sessions.

3. Set Performance Benchmarks

• Go beyond Apple’s minimum requirements and track metrics like launch times, app responsiveness, and network request sizes.
• Use real user monitoring (RUM) tools to surface performance issues affecting specific user subsets.
• Continuously monitor and optimize your app’s performance, especially after new feature additions or code changes.

4. Ensure Data Privacy

• Configure user opt-in mode and data collection levels to respect user privacy preferences.
• Understand what data the OneAgent SDK captures and update your App Store Connect questionnaire accordingly.

Leveraging Custom Actions

Custom actions are a powerful feature of the OneAgent SDK that allow you to track specific user interactions and app behaviors. Here’s how to use them effectively:

Creating Custom Actions

Use the Dynatrace class to create and report custom actions:

swift

Copy

import Dynatrace

let myAction = Dynatrace().enterAction(“MyButton tapped”)

// Perform the action and whatever else is needed

myAction.leaveAction()

Modifying Autogenerated Actions

You can modify autogenerated actions using the Dynatrace.modifyUserAction method:

swift

Copy

import Dynatrace

let userAction = Dynatrace().modifyUserAction()

userAction.setName(“Modified Action Name”)

userAction.reportEvent(“Event Name”, value: 10)

userAction.reportError(“Error Message”)

userAction.cancelAction()

Registering Callbacks for New User Actions

To receive callbacks for newly created user actions:

swift

Copy

import Dynatrace

Dynatrace().registerCallbackForUserActions { userAction in

    userAction.setName(“Modified Action Name”)

    userAction.reportEvent(“Event Name”, value: 10)

    userAction.reportError(“Error Message”)

    userAction.cancelAction()

}

Optimizing HTTP Performance

The OneAgent SDK provides powerful tools for monitoring and optimizing HTTP performance in your iOS app. Here’s a table summarizing the key aspects of HTTP performance optimization using Dynatrace:

Feature	Description	Benefits
Automatic Instrumentation	Tracks common networking APIs	Easy setup, comprehensive monitoring
Manual Instrumentation	For non-HTTP(S) requests	Flexibility for custom protocols
Disable Auto-Instrumentation	For third-party frameworks	Compatibility with external libraries
Backend Correlation	Adds x-dynatrace header	End-to-end visibility
Performance Analytics	Analyzes HTTP metrics	Identifies bottlenecks and issues

By leveraging these features, you can gain deep insights into your app’s HTTP performance and make data-driven optimizations.

Understanding Default Data Capture

It’s essential to know what data the OneAgent SDK captures by default:

1. Web requests using common networking APIs
2. Timing values for instrumented web requests
3. The x-dynatrace HTTP header for server-side correlation

However, the SDK does not automatically capture:

1. GPS location data
2. Non-HTTP(S) requests (e.g., WebSocket, gRPC)
3. Custom events or user interactions

For these additional data points, you’ll need to use manual instrumentation or custom actions.

At Last

The Dynatrace iOS SDK for iOS is a game-changer for mobile app performance monitoring and optimization. By providing real-time insights, customizable instrumentation, and powerful analytics, it empowers iOS developers to deliver exceptional user experiences.

From easy integration to advanced custom actions and HTTP performance optimization, the OneAgent SDK offers a comprehensive solution for ensuring your iOS app performs at its best. By following the best practices and leveraging the full capabilities of the SDK, you can stay ahead of performance issues, reduce crashes, and ultimately, delight your users with a smooth, responsive app experience.

As mobile app performance continues to be a critical factor in user satisfaction and app store success, tools like the Dynatrace OneAgent SDK become indispensable for iOS developers. Embrace this powerful technology, and take your iOS app performance to the next level.
