CrashReporting.reportError(error, withGroupingString: "grouping string")
CrashReporting.report(exception, withGroupingString: "grouping string")
[IBGCrashReporting reportException:exception groupingString:@"grouping string"];
[IBGCrashReporting reportError:error groupingString:@"grouping string"];
CrashReporting.reportException(throwable, "exception identifier", userAttrsMap, "grouping fingerprint");
CrashReporting.reportException(throwable, "exception identifier", userAttrsMap, "grouping fingerprint")
