Features
Here's a list of Sentry's Apple SDK features.
Sentry's Apple SDK enables automatic reporting of errors and exceptions, and identifies performance issues in your application.
The SDK builds a crash report that persists to disk. While it attempts to send the report right after the crash, it may not always work because the environment may be unstable at the time of the crash. If this is the case, the report will be sent upon application start.
Features:
Multiple types of errors are captured, including:
- Mach exceptions
- Fatal signals
- Unhandled exceptions
- C++ exceptions
- Objective-C exceptions
- Error messages of fatalError, assert, and precondition
- App Hang Detection
- Watchdog Terminations
- HTTP Client Errors
- Start-up crashes. The SDK init waits synchronously for up to 5 seconds to flush out events if the app crashes within 2 seconds after the SDK init.
