为什么无法使用Swift将数据保存到plist文件中

Question

** readData.plist为：**

  <?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>currentChapter</key>
    <string>2</string>
    <key>currentLine</key>
    <string>2</string>
    <key>bookname</key>
    <string>ExcelBible</string>
</dict>
</plist>

**以下是代码：**

        let Chapter = currentChapter
        let Line = currentLine
        let name = bookname

        let dict:NSMutableDictionary = NSMutableDictionary()



        dict.setObject("1", forKey: "currentChapter" as NSCopying)
        dict.setObject("1", forKey: "currentLine" as NSCopying)
        dict.setObject("WordBible", forKey: "bookname" as NSCopying)

        //I also use dict[0] = "1", and setValue() method both of them are not work

        let plistPath = Bundle.main.path(forResource: "readData", ofType: "plist")

        dict.write(toFile: plistPath!, atomically: true)

Blockquote我也在这里使用FileManager和几个示例来保存数据，其中一些显示为“ Successfully write”，但文件没有更改。

我认为该文件不在可写位置，因此应在documents目录中创建它。然后，必须从文档目录中读取它。
