SwiftyBeaver destination used to log error traces using Crashlytics

CrashlytisDestination.swift

import Crashlytics
import Foundation
import SwiftyBeaver
import UIKit

public class CrashlyticsDestination: BaseDestination {
    open override func send(_ level: SwiftyBeaver.Level, msg traceMessage: String, thread traceThread: String, file traceFile: String,
                            function traceFunction: String, line traceLine: Int, context _: Any? = nil) -> String? {
        if level == SwiftyBeaver.Level.error {
            let userInfo: [String: Any] = [
                NSLocalizedDescriptionKey: traceMessage,
                "Thread": traceThread,
                "File": traceFile,
                "Function": traceFunction,
                "Line": traceLine,
            ]
            let error = NSError(domain: "Error level: \(level) | Message: \(traceMessage)",
                                code: 1,
                                userInfo: userInfo)
            Crashlytics.sharedInstance().recordError(error)
        }
        return super.send(level, msg: traceMessage, thread: traceThread, file: traceFile, function: traceFunction, line: traceLine)
    }
}

This does no longer work for me on Crashlytics v3.12.0.
Updated version that does work:
