swift开发之--获取当前应用的配置信息

希望能把开发做的更细一点，知其然也知其所以然。

//        获取当前程序可执行文件所在目录
        let mainBundle = Bundle.main
//        获取程序包的识别标识符。
//        该标识符是应用程序的唯一标识，应用于标识符之间是一一对应关系。
//        请注意：应用新建成功后，该标识符将不可修改
        let identifier = mainBundle.bundleIdentifier
//        获取应用程序包的所有配置信息，并存储在字典对象中
        let info = mainBundle.infoDictionary
//        获取当前应用程序的名称
        let bundleId = mainBundle.object(forInfoDictionaryKey: "CFBundleName")
//        获取当前应用的版本号
        let version = mainBundle.object(forInfoDictionaryKey: "CFBundleShortVersionString")
        
//        控制台打印
        print("[identifier]:(identifier!)")
        print("[info]:(info!)")
        print("[bundleId]:(bundleId!)")
        print("[version]:(version!)")

控制台打印如下：
