Get powerful iOS crash reporting
Automatically detect crashes in your iOS apps and get the answers you need to fix them and deliver a crash-free experience
Comprehensive iOS crash reports
Faster debugging with in-depth reports, right out of the box
Upload dSYMs
See a full, desymbolicated stacktrace in every crash report. Debug knowing the exact method name and line number that crashed.
Automatically collect debug info
Capture all the crash data you need to reproduce and fix a bug are automatically collected in a detailed report including device model, OS version, battery state, thread state for all threads, and more.
Automatic breadcrumbs
Common events leading up to a crash are automatically captured, so you can reproduce app crashes with certainty and prove you've fixed a bug. Auto-capture not enough? Go further and customize breadcrumbs using the NSNotification pipeline.
OOM Detection and Reporting
Effectively diagnose and fix the cause of Out of Memory app termination events. Bugsnag automatically captures OOM events and provides powerful diagnostic information including breadcrumbs so you can see the actions users performed in the run-up to these events. Available on native iOS, React Native, and Unity apps.
Intelligent crash grouping
Prioritize the most harmful bugs first, with tools that help you cut through the noise and discover critical bugs
Reliable, best in class error grouping
Identifying which errors happen most and hurt the most users is powered by Bugsnag's intelligent error categorization and grouping. Aggregating errors by root cause decreases noise in your notifications and helps you assess impact.
Powerful filtering and sorting
Find specific errors that need investigating, like those affecting a certain version of your app, or a user reported bug. Filtering updates user and event counts so you can assess impact from a zoomed in view of your crash data.
Know when problems spike
If a backend or API change causes an increase in errors, Bugsnag alerts you immediately. The error spiking algorithm uses an exponential moving average to identify anomalies in your error rate.
Benchmark releases
Use the Releases dashboard to decide if a release is successful or needs to be rolled back. The crash rate indicator shows the percentage of sessions in a release that end in a crash, allowing you to compare release health and track improvements over time.
Built for effective iOS crash detection
Thoughtfully built with mobile crash reporting requirements in mind
Swift and Objective C support
Whether you're writing your iOS apps in Swift or Objective C, Bugsnag will capture all unhandled and handled exceptions and report them to you.
Begin in minutes or dig deeper
You'll see value in minutes with Bugsnag's quick installation, but if you need to dig deeper, you can customize at the nuts and bolts level to meet your requirements.
