Introduction to iOS monitoring

New Relic's mobile monitoring for iOS gives you a comprehensive view of your app's performance. It works for iOS apps written using Objective-C, Swift, or both languages. For a general overview of mobile monitoring functionality, see Introduction to mobile monitoring.

Compatibility and requirements

Before you install the iOS agent, review the compatibility and requirements.

Install the agent

As part of the installation process, New Relic automatically generates an application token. This is a 40-character hexadecimal string for authenticating each mobile app that you monitor.

There are two ways you can install the iOS agent:

Extend your instrumentation

After you install the agent, you can extend the agent's default instrumentation with various types of custom data:

To access:

In the mobile UI:

In New Relic dashboards:

Custom data

Create and record custom events, interaction traces, and attributes to add details to your existing data and traces.

You can also query the custom events that you created in New Relic dashboards and NRQL.

Network requests

Enable the MobileRequest event feature so you can perform a full network analysis.

To further investigate network request error rates and response times, query MobileRequest and MobileRequestError events.

Crash analysis

Review detailed information using groups and filters to analyze trends that lead to crashes.

To view more information about crashes, create NRQL queries to review Insights charts related to crash data.

iOS SDK API

Use the iOS SDK API to instrument parts of your code that are not instrumented by default.

Then, view those custom events and attributes in New Relic Insights.

Handled exceptions

Report exceptions so you can identify factors creating a poor mobile app experience.

To further improve performance, review MobileHandledException event records in New Relic Insights.

Breadcrumbs

Boost the level of detail in crash event trails by adding breadcrumbs.

Then, query MobileBreadcrumbs events to see all breadcrumbs or just breadcrumbs related to crashes.
