Datadog's RUM iOS SDK enables developers to collect comprehensive crash data from their iOS apps, allowing them to track, triage, and debug recurring issues. By using the SDK, developers can visualize crash data in dashboards, analyze symbolicated error reports, and identify key information about app resources throwing errors, most common error types, and iOS versions experiencing crashes. Additionally, Datadog's Error Tracking feature groups similar errors together into issues, providing debugging info from the app alongside user session info, helping developers understand the scope of crashes and focus their debugging efforts on the most severe and frequent issues. With this setup, developers can easily track, triage, and debug application crashes to manage their impact on users and reduce churn.
