当我正在初始化实体的实例时,我收到了错误Variable used within its own initial value.

这是抛出错误的代码:

class func buildWordDefinition (word:String, language:Language, root:TBXMLElement) -> WordDefinition
    {
        let word = WordDefinition(word: word, language: language)

错误指向word变量.

这是WordDefinition类:

class WordDefinition {
    let word: String
    let language: Language

    init(word: String, language:Language)
    {
        self.word = word
        self.language = language
    }
}

这个错误是什么意思 ？
