## What it does

The skill inspects a KMP project’s CocoaPods setup, adds the `swiftPMDependencies {}` DSL, and changes `pod()` calls to `swiftPackage()`. It also rewrites `cocoapods.*` imports as `swiftPMImport.*`, then helps reconfigure the iOS project and remove CocoaPods.

The work is split into phases: verify the Kotlin build, update Gradle, transform source imports, reconfigure Xcode, remove the old plugin, and check the resulting builds. The process writes `MIGRATION_REPORT.md`. It also checks third-party KMP libraries with bundled cinterop klibs, since some of their `cocoapods.*` imports must remain unchanged.

The project needs Kotlin 2.4.0-Beta2 or later, Xcode 16.4 or 26.0+, and an iOS Deployment Target of 16.0+ is recommended. If Kotlin must be upgraded from an older version, that jump can introduce unrelated breaking changes, so verify the project before continuing.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Kotlin/kotlin-agent-skills --skill kotlin-tooling-cocoapods-spm-migration -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/kotlin-tooling-cocoapods-spm-migration/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/kotlin-tooling-cocoapods-spm-migration/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Kotlin/kotlin-agent-skills --skill kotlin-tooling-cocoapods-spm-migration -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/kotlin-tooling-cocoapods-spm-migration/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Kotlin/kotlin-agent-skills --skill kotlin-tooling-cocoapods-spm-migration -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/kotlin-tooling-cocoapods-spm-migration/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Kotlin/kotlin-agent-skills kotlin-tooling-cocoapods-spm-migration
```

2. **Manually: put the files in place**
- File: `.github/skills/kotlin-tooling-cocoapods-spm-migration/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Kotlin/kotlin-agent-skills --skill kotlin-tooling-cocoapods-spm-migration -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Kotlin/kotlin-agent-skills --path skills/kotlin-tooling-cocoapods-spm-migration
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/kotlin-tooling-cocoapods-spm-migration/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Kotlin/kotlin-agent-skills --skill kotlin-tooling-cocoapods-spm-migration -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/Kotlin/kotlin-agent-skills/tree/HEAD/skills/kotlin-tooling-cocoapods-spm-migration/SKILL.md

## When to use it
- move KMP dependencies from CocoaPods to Swift Package Manager
- replace `pod()` calls with `swiftPackage()` in Gradle
- rewrite `cocoapods.*` imports as `swiftPMImport.*`
- reconfigure the Xcode project after migration
- verify Kotlin and iOS project builds

## Example prompts
- Migrate this KMP project from CocoaPods to Swift Package Manager and run every migration phase.
- Inspect `build.gradle.kts`, find the modules using CocoaPods, and create `MIGRATION_REPORT.md`.
- Check `cocoapods.*` imports, account for bundled cinterop klibs, and reconfigure the Xcode project.

# CocoaPods to SwiftPM Migration for KMP

Migrate Kotlin Multiplatform projects from `kotlin("native.cocoapods")` to `swiftPMDependencies {}` DSL.

## Requirements

- **Kotlin**: 2.4.0-Beta2 or later (first public release with `swiftPMDependencies` support, available on Maven Central)
- **Xcode**: 16.4 or 26.0+
- **iOS Deployment Target**: 16.0+ recommended

## Migration Overview

**IMPORTANT**: Keep the `cocoapods {}` block and plugin active until Phase 6. The migration adds `swiftPMDependencies {}` alongside the existing CocoaPods setup first, reconfigures Xcode, and only then removes CocoaPods.

| Phase | Action |
|-------|--------|
| 1 | Analyze existing CocoaPods configuration |
| 2 | Update Gradle configuration (repos, Kotlin version) |
| 3 | Add `swiftPMDependencies {}` alongside existing `cocoapods {}` |
| 4 | Transform Kotlin imports |
| 5 | Reconfigure iOS project and deintegrate CocoaPods |
| 6 | Remove CocoaPods plugin from Gradle |
| 7 | Verify Gradle build and Xcode project build |
| 8 | Write MIGRATION_REPORT.md |

## Phase 1: Pre-Migration Analysis

### 1.0 Verify the project builds

Before starting migration, identify the module to migrate and confirm it compiles successfully.

1. **Find the module that uses CocoaPods** — look for `build.gradle.kts` files containing `cocoapods`:
   ```bash
   grep -rl "cocoapods" --include="build.gradle.kts" .
   ```
   Extract the module name from the path (e.g., `./shared/build.gradle.kts` → module name is `shared`). Note: multiple modules may use CocoaPods — record all of them. Typically only the module that produces the framework linked into the iOS app needs `swiftPMDependencies`; the others only need CocoaPods removed (Phase 6).

2. **Compile Kotlin code** — run the Kotlin compilation task for that module to verify the Kotlin source compiles:
   ```bash
   ./gradlew :moduleName:compileKotlinIosSimulatorArm64
   ```
