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：

[identifier]:com.yaosecu.DemoApp01
[info]:["DTPlatformVersion": 14.2, "UIStatusBarStyle": UIStatusBarStyleDarkContent, "CFBundleDevelopmentRegion": en, "CFBundlePackageType": APPL, "UILaunchStoryboardName": LaunchScreen, "LSRequiresIPhoneOS": 1, "MinimumOSVersion": 13.0, "DTXcodeBuild": 12B45b, "UIApplicationSceneManifest": {

                UISceneConfigurationName = "Default Configuration";
                UISceneDelegateClassName = "DemoApp01.SceneDelegate";
                UISceneStoryboardFile = Main;
            }
        );
    };
