将ARReferenceObject上传到云数据库Parse

Question

有人有将ARReferenceObject保存到云数据库（例如Parse）的经验吗？我试试这个：

guard let testRun = self.testRun, let object = testRun.referenceObject, let name = object.name else {
        print("Error: Missing scanned object.")
        return
    }

    DispatchQueue.global().async {

        // save object to Parse
        let parseARObjects = PFObject(className: "ARReferenceObjects")
        parseARObjects.setObject(object, forKey: "ARObject")

        parseARObjects.saveEventually{ (success: Bool, error: Error?) ->
            Void in
            if (success) {
                print("ARObject saved to cloud")
            } else if error != nil {
                print("error saving object to cloud")
            }
        }

这崩溃并出现错误：由于未捕获的异常“ NSInvalidArgumentException”而终止应用程序，原因：“ PFObject值可能没有类：ARReferenceObject”。
