We have the same issue, is there any progress on this?

In my case, it's due to some unexpected NaN values in my tracking data. So I ended up creating the below extension for dictionary

extension Dictionary where Key == String, Value == Any {
    func removeInvalidValues() -> [String : Any]? {
        return filter { (_, value) in
            if let numberValue = value as? NSNumber {
                return !numberValue.floatValue.isNaN
            }
            return !(value is NSNull)
        }
    }
}

Usage:

var properties: [String: Any] = myTrackingData
Analytics.shared().track(event, properties: properties.removeInvalidValues())
