swift - 单步执行 Plist 并编写

Question

我创建了一个供个人使用的应用程序，用于将数据从 BundlePath 中的模板写入两个 Plist 文件。在 Swift 3 之前一直工作得很好，我不确定是否将模板的索引作为键传递。

for index in 0 ..< number {


        var diction = (resultQDictionary?.object(forKey: "Questions"))

        print("diction = \(diction)")

//PROBLEM HERE!! - cannot call value of non function type 'Any?!' for dictionaryQItem and dictionaryAItem 

        var dictionaryQItem = (resultQDictionary?.object(forKey: "Questions") as AnyObject).object(index)
        var dictionaryAItem = (resultADictionary?.object(forKey: "Answers") as AnyObject).object(index)

        print("dQitem = \(dictionaryQItem)")

        //print("this is DI for question = \(dictionaryItem?.objectForKey("Question"))")
        //print(dictionaryItem?.objectForKey("Title"))



        var cAns = inputSheetObjectArrayKey[index] //c
        var quest = questionArray[index]
        var title = titleArray[index]
        var block = pickerBlock // blockArray[index]

        var answerA = answerAArray[index]
        var answerB = answerBArray[index]
        var answerC = answerCArray[index]

        //print("quest = \(quest)")

        let trimmedcAns = (cAns as AnyObject).trimmingCharacters(in: CharacterSet.whitespaces)
        let trimmedQuest = quest.trimmingCharacters(in: CharacterSet.whitespaces)
        let trimmedTitle = title.trimmingCharacters(in: CharacterSet.whitespaces)
        //let trimmedBlock = block.stringByTrimmingCharactersInSet(NSCharacterSet.whitespaceCharacterSet())
        let trimmedAnswerA = answerA.trimmingCharacters(in: CharacterSet.whitespaces)
        let trimmedAnswerB = answerB.trimmingCharacters(in: CharacterSet.whitespaces)
        let trimmedAnswerC = answerC.trimmingCharacters(in: CharacterSet.whitespaces)



        dictionaryQItem.setValue(trimmedcAns, forKey: "CorrectAnswer")
        dictionaryQItem.setValue(trimmedQuest, forKey: "Question")
        dictionaryQItem.setValue(trimmedTitle, forKey: "Title")
        dictionaryQItem.setValue(pickerBlock, forKey: "Block")



        dictionaryAItem.setValue(trimmedAnswerA, forKey: "A")
        dictionaryAItem.setValue(trimmedAnswerB, forKey: "B")
        dictionaryAItem.setValue(trimmedAnswerC, forKey: "C")
        dictionaryAItem.setValue(trimmedTitle, forKey: "Title")
        dictionaryAItem.setValue(" ", forKey: "FEEDBACK")


    }

    resultQDictionary?.write(toFile: docsQPath, atomically: false)
    resultADictionary?.write(toFile: docsAPath, atomically: false)


}

无法调用非函数类型“Any?!”的值对于dictionaryQItem和dictionaryAItem - 在Swift 2.3中工作得很好，但我不确定如何传递索引。任何帮助表示赞赏!

我将 DictionaryAItem 和 DictionaryQItem 定义为类对象，并使用它们来管理问题和答案数据，特别是当您似乎具有明确定义的结构时。
