将扩展集成到大型iOS应用程序中

Written by Artur Stepaniuk and Max Husar

Today, when you open Apple Maps and choose a destination, you are able to see a list of available Lyft offers, seamlessly routing you to the Lyft app to book your next ride. To create this fluid and user-friendly experience across the iOS ecosystem, however, engineers must tackle a range of technical challenges, from managing dependencies in a highly modular application to optimizing performance while maintaining a high quality user experience.

今天，当您打开Apple Maps并选择一个目的地时，您可以看到一系列可用的Lyft优惠，顺利地将您引导到Lyft应用程序以预订您的下一次行程。然而，为了在iOS生态系统中创建这种流畅且用户友好的体验，工程师们必须解决一系列技术挑战，从在高度模块化的应用程序中管理依赖项到优化性能，同时保持高质量的用户体验。

Disclaimer: For the purpose of this deep dive, we assume that you have a general understanding of what a build system is, including concepts like modules, static/dynamic frameworks, dependency graphs and build settings customization via flags.

From an implementation perspective, this involves creating a separate application extension. Detailed descriptions of API for booking rides can be found in the relevant Apple documentation, which includes multiple code examples.

从实现的角度来看，这涉及创建一个单独的应用程序扩展。有关预订乘车的 API 的详细描述可以在相关的 Apple 文档中找到，其中包括多个代码示例。

Let’s explore the architectural nuances, challenges faced during development, and solutions implemented to overcome these obstacles:

让我们探讨一下架构的细微差别、开发过程中遇到的挑战以及为克服这些障碍而实施的解决方案：

The Dependency Jungle and how to manage constraints in a highly modular application, complying with RAM and binary size limitations;
