WWDC20 10118 - Create app clips for other businesses 视频
这个主题讲述如何为其他商户构建 App Clips 体验，例如某外卖 App 如何帮各个不同餐饮商户构建基于他们自己品牌的 App Clips 来支持预定餐桌，点餐等服务。只需在一个主 App 中创建唯一的 App Clips 库就可以为不同商户提供各自独特的 App Clip 体验。同时讲述了 App Clips 的最佳实践，包括如何上传独特的商户信息，处理入口链接，路由推送消息，处理存储和恢复会话状态等等。也讲述了各种 App Clips 体验图标类型的差异性，如何呈现和定制这些图标。
