Build for iOS and macOS | Codex use cases

[!tip] 中文标题 使用 Codex 搭建 SwiftUI 项目脚手架,通过 xcodebuild 或 Tuist 保持 CLI 优先的构建循环,并在深入工作时添加 XcodeBuildMCP 或专门的 SwiftUI 技能

[!abstract] 摘要 本文介绍了如何利用 OpenAI 的 Codex 来高效搭建和迭代 SwiftUI 项目。核心是保持 CLI 优先的工作流,使用 xcodebuild 或 Tuist 进行构建,避免依赖 Xcode 图形界面。对于新建项目,可从基础提示开始搭建应用脚手架和构建脚本;对于现有项目,则可利用 XcodeBuildMCP 进行更深度的自动化,如管理方案、启动模拟器、截图等。文章推荐在需要时引入专门的 SwiftUI 技能(如性能审计、视图重构)来提升代码质量,并强调通过小范围、可信的验证循环来确保每次更改的有效性,从而提高开发效率。

起始提示

搭建一个初始的 SwiftUI 应用,并添加一个构建和启动脚本,以便我可以将其连接到本地环境中的 Build 操作。约束条件:- 保持 CLI 优先。优先使用 Apple 的 xcodebuild;如果更简洁的设置有帮助,也可以使用 Tuist。- 如果此仓库已包含完整的 Xcode 项目,请使用 XcodeBuildMCP 列出目标、选择正确的方案、构建、启动并在迭代过程中捕获截图。- 重用现有的模型、导航模式和共享工具。- 保持 iOS 和 macOS 的兼容性,除非我明确将工作范围限定在一个平台。- 每次更改后使用一个小的可信验证循环,仅当较窄的检查通过后才扩展到更广泛的构建。- 告诉我您是将此视为全新的脚手架还是现有项目的更改。交付物:- 应用脚手架或请求的功能切片- 一个包含确切命令的小型构建和启动脚本- 您运行的最小相关验证步骤- 您使用的确切方案、模拟器和检查

搭建应用和构建循环

对于全新的工作,从简单的提示开始。要求 Codex 搭建一个初始的 SwiftUI 应用,并编写一个小的构建和启动脚本,以便您可以将其连接到本地环境中的 Build 操作。

保持循环的 CLI 优先。Apple 的 xcodebuild 可以从终端列出方案并处理构建、测试、归档、build-for-testingtest-without-building 操作,这使 Codex 可以保持在智能体循环中,而不是跳转到 Xcode 图形界面。

如果您想要一个更简洁的项目生成器,并且对第三方工具感到满意,Tuist 是一个很好的下一步选择。它可以在不需要图形界面的情况下生成和构建 Xcode 项目,同时仍然允许 Codex 从终端构建和启动应用。

一旦您进入完整的 Xcode 项目并需要更深度的自动化时,请使用 XcodeBuildMCP。当方案、目标、模拟器控制、截图、日志和 UI 交互变得足够重要,以至于普通的 shell 命令不再是全部时,就到了这个阶段。

利用技能

对于第一轮,您通常不需要技能或 MCP 服务器。一旦工作变得专业化,或者您希望将更强的 SwiftUI 约定融入运行时,再添加技能。

迭代

一旦您有了一个可行的第一轮,或者如果您是从现有项目开始的,就可以开始迭代 UI 或行为。

对于这一部分,请明确说明您想要更改什么以及如何更改。

使该提示层明确:告诉 Codex 它是在全新的仓库中工作还是在现有的 Xcode 项目中工作,哪些平台必须保持工作状态,以及您期望的验证循环是什么。

示例提示

例如,如果您想为现有应用添加一个功能,可以像这样要求 Codex 进行更改:

为此 SwiftUI 应用添加入门流程。约束条件:- 重用现有的模型、导航模式和共享工具。- 使用 XcodeBuildMCP 列出正确的目标或方案,构建应用,启动它,并在需要视觉验证时捕获截图。- 保持 iOS 和 macOS 的兼容性,除非我明确将工作范围限定在一个平台。- 确切地告诉我您使用了哪个方案、模拟器和检查。实现该功能切片,使用最小相关的构建或运行循环进行验证,并总结更改内容。

实用技巧

从基础开始

对于全新的工作,从简单的提示开始。要求 Codex 搭建一个初始的 SwiftUI 应用,并编写一个小的构建和启动脚本,以便您可以将其连接到本地环境中的 Build 操作。对于第一轮,您通常不需要任何技能或 MCP 服务器。

使用小的可信验证循环

告诉 Codex 在每次更改后运行最窄的命令,以实际证明您所触及的约定。稍后再扩展到更广泛的构建。这使 Codex 保持快速,而不会假装每次编辑都需要完整的应用构建。

保持循环的 CLI 优先

保持循环的 CLI 优先。Apple 的 xcodebuild 工具可以从终端列出方案并运行构建、测试、归档、build-for-testingtest-without-building 操作,这使 Codex 可以保持在智能体循环中,而不是跳转到 Xcode 图形界面。

利用 XcodeBuildMCP

一旦您进入完整的 Xcode 项目并需要更深度的自动化,就使用 XcodeBuildMCP。当方案、目标、模拟器控制、截图、日志和 UI 交互变得足够重要,以至于普通的 shell 命令不再是全部时,就到了这个阶段。

技术栈

UI 框架

SwiftUI

在 Apple 平台上原型化视图、导航和共享状态的最快方式,同时保持 UI 代码的可读性。

构建工具

xcodebuild 或 Tuist

两者都使本地构建循环保持在终端中,而不是依赖 Xcode 图形界面。

项目自动化

XcodeBuildMCP

一旦您需要 Codex 检查方案和目标、启动应用、捕获截图并在不离开智能体循环的情况下继续迭代时,这是一个强大的选择。

分发工具

App Store Connect CLI

让您的智能体完全处于循环中,并将您的应用构建直接发送到 App Store。

Starter prompt

Scaffold a starter SwiftUI app and add a build-and-launch script I can wire to a `Build` action in my local environment. Constraints: - Stay CLI-first. Prefer Apple's `xcodebuild`; if a cleaner setup helps, it's okay to use Tuist. - If this repo already contains a full Xcode project, use XcodeBuildMCP to list targets, pick the right scheme, build, launch, and capture screenshots while you iterate. - Reuse existing models, navigation patterns, and shared utilities when they already exist. - Keep iOS and macOS compatibility intact unless I explicitly scope the work to one platform. - Use a small trustworthy validation loop after each change, then expand to broader builds only when the narrower check passes. - Tell me whether you treated this as a greenfield scaffold or an existing-project change. Deliver: - the app scaffold or requested feature slice - a small build-and-launch script with the exact commands - the smallest relevant validation steps you ran - the exact scheme, simulator, and checks you used

Scaffold the app and build loop

For greenfield work, start with plain prompting. Ask Codex to scaffold a starter SwiftUI app and write a small build-and-launch script you can wire to a Build action in a local environment.

Keep the loop CLI-first. Apple’s xcodebuild can list schemes and handle build, test, archive, build-for-testing, and test-without-building actions from the terminal, which lets Codex stay in an agentic loop instead of bouncing into the Xcode GUI.

If you want a cleaner project generator and you’re comfortable with third-party tooling, Tuist is a good next step. It can generate and build Xcode projects without needing the GUI, while still letting Codex build and launch the app from the terminal.

Use XcodeBuildMCP once you’re inside a full Xcode project and need deeper automation. That’s when schemes, targets, simulator control, screenshots, logs, and UI interaction matter enough that plain shell commands stop being the whole story.

Leverage skills

For the first pass, you often don’t need a skill or MCP server. Add skills once the work gets specialized or you want stronger SwiftUI conventions baked into the run.

To learn more about how to install and use skills, see our skills documentation.

Iterate

Once you have a first pass working, or if you’re starting from an existing project, you can start iterating on the UI or behavior.

For this part, be specific about what you want to change and how you want to change it.

Make that prompting layer explicit: tell Codex whether it’s working in a greenfield repo or an existing Xcode project, which platforms must keep working, and what validation loop you expect.

Example prompt

For example, if you want to add a feature to an existing app, you can ask Codex for a change like this:

Add the onboarding flow for this SwiftUI app. Constraints: - Reuse existing models, navigation patterns, and shared utilities. - Use XcodeBuildMCP to list the right targets or schemes, build the app, launch it, and capture screenshots if you need visual verification. - Keep iOS and macOS compatibility intact unless I explicitly scope the work to one platform. - Tell me exactly which scheme, simulator, and checks you used. Implement the slice, verify it with the smallest relevant build or run loop, and summarize what changed.

Practical tips

Start with basics

Start with plain prompting for greenfield work. Ask Codex to scaffold a starter SwiftUI app and write a small build-and-launch script you can wire to a Build action in a local environment. For that first pass, you often don’t need any skill or MCP server.

Use a small trustworthy validation loop

Tell Codex to run after each change the narrowest command that actually proves the contract you touched. Expand to broader builds later. This keeps Codex fast without pretending a full app build is required for every edit.

Keep the loop CLI-first

Keep the loop CLI-first. Apple’s xcodebuild tool can list schemes and run build, test, archive, build-for-testing, and test-without-building actions from the terminal, which lets Codex stay in an agentic loop instead of bouncing into the Xcode GUI.

Leverage XcodeBuildMCP

Use XcodeBuildMCP as soon as you are inside a full Xcode project and need deeper automation. That’s the point where schemes, targets, simulator control, screenshots, logs, and UI interaction matter enough that plain shell commands stop being the whole story.

Tech stack

UI framework

SwiftUI

The fastest way to prototype views, navigation, and shared state across Apple platforms while keeping the UI code readable.

Build tooling

xcodebuild or Tuist

Both keep the native build loop in the terminal instead of depending on the Xcode GUI.

Project automation

XcodeBuildMCP

A strong option once you need Codex to inspect schemes and targets, launch the app, capture screenshots, and keep iterating without leaving the agentic loop.

Distribution tooling

App Store Connect CLI

Keep your agent fully in the loop and send your app build directly to the App Store.
