The following functions are available globally.

  • Logs a message to the Firebase Crash Reporter system.

    This method adds a message to the crash reporter logging system. The recent logs will be sent with the crash report when the application exits abnormally. Note that the timestamp of this message and the timestamp of the console message may differ by a few milliseconds.

    Messages should be brief as the total size of the message payloads is limited by the uploader and may change between releases of the crash reporter. Excessively long messages will be truncated safely but that will introduce a delay in submitting the message.

    Warning

    Raises an NSInvalidArgumentException if @p format is nil.

    Declaration

    Swift

    func FIRCrashLogv(_ format: String, _ ap: CVaListPointer)

    Objective-C

    extern void FIRCrashLogv(NSString *_Nonnull format, va_list ap)

    Parameters

    format

    A format string.
    ap

    A variable argument list.

    A comma-separated list of arguments to substitute into format.

  • Logs a message to the Firebase Crash Reporter system in a way that is easily called from Swift code.

    This method adds a message to the crash reporter logging system. Similar to FIRCrashLog, but with a call signature that is more Swift friendly. Unlike FIRCrashLog, callers use string interpolation instead of formatting arguments.

    @code public func mySwiftFunction() { let unexpected_number = 10; FIRCrashMessage(This number doesn’t seem right: \(unexpected_number)); } @endcode

    Messages should be brief as the total size of the message payloads is limited by the uploader and may change between releases of the crash reporter. Excessively long messages will be truncated safely but that will introduce a delay in submitting the message.

    FIRCrashLog(format, …)

    Declaration

    Swift

    func FIRCrashMessage(_ message: String)

    Objective-C

    static inline void FIRCrashMessage(NSString *_Nonnull message)

    Parameters

    Message

    A log message
