Question

我正在尝试解析一个plist。

下面给出了代码段：

if let path = Bundle.main.path(forResource: Constants.plistName,    ofType: Constants.plistType) {

       guard let myDictionary = NSDictionary(contentsOfFile: path) else {
           //throw some error
       } }

如果我将myDictionary的类型设置为Dictionary，我就不能再使用contentsOfFile方法了。请帮忙。

（推荐）替代方案为PropertyListSerialization

let url = Bundle.main.url(forResource: Constants.plistName, withExtension: Constants.plistType)!
let data = try! Data(contentsOf: url)
let myDictionary = try! PropertyListSerialization.propertyList(from: data, format: nil) as! [String:Any]

替代swift中的objective-NSDictionary（contentsOfFile）方法
