Simulator State as Code for iOS developers, CI, and AI agents—capture, diff, plan, and safely apply reproducible simulator profiles through a deterministic Swift CLI and MCP server.

Project Overview项目介绍

awesome-ios-sim is a declarative tool for managing iOS Simulator state as versioned code, built for iOS developers, CI pipelines, and AI coding agents. It provides a standalone deterministic CLI and an MCP stdio server, and it can also be installed as a plugin bundle for DeepSeek Harness. To install from source, clone the repository, cd into the project directory, and run swift build -c release to produce the main ios-sim-state CLI and the ios-sim-state-mcp MCP server. For pre-built binaries, you can install via the official Homebrew tap with brew tap qubyyang/awesome-ios-sim followed by brew install awesome-ios-sim.

awesome-ios-sim solves the common problem of irreproducible iOS test environments caused by scattered shell scripts, undocumented default settings, and manual simulator setup. It enables a consistent workflow that starts with a target state profile and a current snapshot, generates a diff, produces an ordered execution plan, requires explicit confirmation, and only applies changes after review. This workflow is ideal for development teams that need consistent, reproducible test environments and AI agents that need a safe, typed interface to interact with iOS simulators. All changes are auditable, and the default behavior for all apply operations is a dry run that does not mutate any existing simulator state.

This project is currently in alpha, with a v1alpha1 state schema, and it is released under the open source MIT license. It requires macOS 13 or later, Swift 6, and a full installation of Xcode with an iOS Simulator runtime for live operations like inventory, snapshot, and apply. Command Line Tools for Xcode can be used to build the package, but they do not include CoreSimulator or simctl, so live operations will not work. The project currently publishes unsigned, unnotarized pre-release builds, and users are always warned to review plans before applying, especially plans that include erase or remove operations.

awesome-ios-sim 是一个为 iOS 开发者、CI 流水线和 AI 智能体设计的 iOS 模拟器状态即代码工具,提供确定性命令行接口和 MCP 标准输入输出服务器,同时也可作为 DSH 插件包安装。它将 iOS 模拟器配置转换为可版本化的配置文件,支持捕获、对比差异、生成计划、审核和安全应用操作。它仅调用 Apple 官方 xcrun simctl,不使用私有框架,全程本地运行,无后台守护进程、云账户或遥测数据收集。

该工具面向需要可复现测试环境的 iOS 开发团队和使用 AI 辅助开发的工程师,解决了当前模拟器自动化多依赖零散脚本、无文档默认配置和手动设置导致环境难以复现的问题。标准工作流为:从目标配置文件和当前快照生成差异,输出确定性操作计划,经明确确认后再审核执行。整个过程声明式可版本化,操作计划可提前检查,对 AI 智能体来说更安全可控。

该项目目前处于 alpha 版本,状态模式为 v1alpha1,使用 MIT 许可证开源。依赖要求为 macOS 13 或更高版本、Swift 6 和完整带 iOS 模拟器运行时的 Xcode,仅命令行工具无法完成实时操作。目前发布的预编译版本尚未经过开发者 ID 签名和苹果公证,应用执行计划前,尤其是包含擦除操作的计划一定要仔细审核。

Simulator State as Code for iOS developers, CI pipelines, and AI agents.

awesome-ios-sim turns an iOS Simulator setup into a versioned profile that can be captured, diffed, planned, reviewed, and safely applied. It provides both a deterministic CLI and an MCP stdio server. It is also installable as a dsh-plugin bundle for DeepSeek Harness.

Project status: alpha. The state schema is v1alpha1. Review generated plans before applying them, especially plans containing erase or app removal operations.

Why this exists

Simulator automation is usually spread across shell scripts, undocumented defaults, and manual setup. That makes test environments difficult to reproduce and gives AI agents an unsafe, untyped shell surface.

This project introduces one workflow:

profile + current snapshot -> diff -> deterministic plan -> explicit confirmation -> audited apply
  • Declarative: commit simulator profiles next to tests and application code.
  • Reviewable: inspect the exact ordered operation plan before mutation.
  • Agent-safe: MCP tools use JSON Schema and simulator_apply defaults to dry-run.
  • Capability-aware: exact, best-effort, and unsupported state are reported explicitly.
  • Public API only: mutations go through Apple's xcrun simctl; no private CoreSimulator frameworks.
  • Local-first: no daemon, cloud account, telemetry, or API key.
