ios - "Expression was too complex to be solved in reasonable time"在 swift 3 中向字典添加数据时，在 swift 2.3 中工作正常

Question

let parameters : [String : AnyObject] = [
    "address" :      txtAddress.text ?? "",
    "person_name" :  txtAuthorName.text ?? "",
    "person_image" : imgUrl ?? "", 
    "book_title" :   txtBookTitle.text ?? "", 
    "dedicated_to" : txtDedicatedTo.text ?? "" , 
    "person_about" : txtAboutTheAuthor.text ?? "",
    "is_published" : false,
    "recipes" : recipeArr  ?? ""]

这是向字典添加数据的代码。在 Swift2.3 上运行良好。

Swift 3 编译器表示将表达式分解为子表达式。

请提出一个合适的解决方案。
