public class CrashlyticsDestination: BaseDestination {
    
    override var defaultHashValue: Int {return 3}
    
    public override init() {
        super.init()
        self.colored = false
    }
    
    // print to Xcode Console. uses full base class functionality
    override func send(level: SwiftyBeaver.Level, msg: String, path: String, function: String, line: Int) -> String? {
        let formattedString = super.send(level, msg: msg, path: path, function: function, line: line)
        
        if let str = formattedString {
            CLSLogv(str, getVaList([]))
        }
        return formattedString
    }

}

Here is a simple SwiftyBeaver logging destination that adds log messages to your Crashlytics crash reports

There will be a crash when str = "%d %@".

You should replace CLSLogv(str, getVaList([])) with CLSLogv("%@", getVaList([ str ]))
