```swift
if let nonFatal = CrashReporting.report(exception) {
    nonFatal.stackTraceMode = .callerThreadOnly 
    nonFatal.report()
}
```

{% endtab %}

{% tab title="iOS - ObjC" %}

```objectivec
LCQNonFatalError *nonFatal = [LCQCrashReporting error:error];
nonFatal.stackTraceMode = LCQNonFatalStackTraceModeCallerThreadOnly
