希望能把開發做的更細一點，知其然也知其所以然。

//        獲取當前程式可執行檔案所在目錄
        let mainBundle = Bundle.main
//        獲取程式包的識別識別符號。
//        該識別符號是應用程式的唯一標識，應用於識別符號之間是一一對應關係。
//        請注意：應用新建成功後，該識別符號將不可修改
        let identifier = mainBundle.bundleIdentifier
//        獲取應用程式包的所有配置資訊，並存儲在字典物件中
        let info = mainBundle.infoDictionary
 
//        獲取當前應用程式的名稱
        let bundleId = mainBundle.object(forInfoDictionaryKey: "CFBundleName")
//        獲取當前應用的版本號
        let version = mainBundle.object(forInfoDictionaryKey: "CFBundleShortVersionString")
