StoreKit 2 的迁移涉及将应用程序从原始的 StoreKit API 更新到 StoreKit 2。以下是迁移的优缺点：
优点：
- 现代化的语言特性：StoreKit 2 使用 Swift 的 Async/Await 模式，这使得执行任务如获取产品元数据、购买和检索客户交易历史变得更加简单和高效。
- 自动验证：StoreKit 2 自动为您执行加密验证，简化了开发过程。
- 历史记录访问：客户的交易历史和订阅续订信息始终可供应用访问，提供了更好的用户体验。
- 向后兼容：通过 Swift 的 back deployed 属性，即使应用安装在旧操作系统的设备上，也可以访问新的 App Store 功能。
- 增强的工具集：StoreKit 2 提供了一整套工具，使处理应用内购买变得更加容易。
缺点：
- 学习曲线：开发者需要学习和适应新的 API 和编程模式。
- 迁移工作量：现有应用需要进行代码更新和测试，以确保迁移到 StoreKit 2 后的功能正常。
