2022年WWDC主题演讲带来了一个意外的惊喜，苹果公司揭示了新的Live Activities功能，以Uber的Rider应用程序作为一个突出的例子。这个宣布为即将到来的功能带来了兴奋，并为我们团队展开了一段令人激动的旅程。

What follows is the story of how we started designing for surfaces outside the app, the engineering problems we had to solve along the way, and ultimately how we measurably improved the experience of riders and drivers.

接下来是我们开始为应用外的界面设计的故事，我们在这个过程中需要解决的工程问题，以及我们如何通过可衡量的方式改善乘客和司机的体验。

Given the secretive nature of the announcement,  only a few directors on our side were in the loop. For the rest of the engineering and design team, it was an exhilarating surprise, immediately followed by the realization that we needed to move quickly.

鉴于公告的保密性质，我们这边只有少数几位主管知情。对于其他工程和设计团队来说，这是一个令人振奋的惊喜，紧接着就意识到我们需要迅速行动。

At a company the size of Uber, work is usually planned on a half-year schedule and resources and timelines are always tight.  So, while considering the prioritization of this feature, we recognized the potential upside of being in the App Store® on day one, to be a champion of the platform.  We also believed that this feature would be of great benefit to our users, as now they would be able to observe trip updates from outside of the app in a granular way.

在Uber这样规模的公司中，工作通常按半年计划进行，资源和时间表总是紧张的。因此，在考虑这个功能的优先级时，我们意识到在第一天就进入App Store®，成为平台的冠军的潜在好处。我们还相信，这个功能将对我们的用户带来巨大的好处，因为现在他们将能够以细粒度的方式观察应用程序之外的行程更新。

We got into a room and began redrawing our plans, reallocating resources, starting from a minimal team that could work on this as their main project. We then recruited additional resources on a side project basis, making sure to plan their contributions to avoid too much context switching.

我们聚在一起重新制定计划，重新分配资源，从一个能够将此作为主要项目进行工作的最小团队开始。然后，我们根据辅助项目的需要招募额外的资源，确保计划他们的贡献，以避免过多的上下文切换。

We began by tech-proofing the concept as much as possible up fro...
