# callStackReturnAddresses

The call return addresses related to a raised exception.

```
var callStackReturnAddresses: [NSNumber] { get }
```

## Discussion

An array of [`NSNumber`](/documentation/Foundation/NSNumber) objects encapsulating <doc://com.apple.documentation/documentation/ObjectiveC/NSUInteger> values. Each value is a call frame return address. The array of stack frames starts at the point at which the exception was first raised, with the first items being the most recent stack frames.

`NSException` subclasses posing as the `NSException` class or subclasses or other API elements that interfere with the exception-raising mechanism may not get this information.
