## What it does

The skill starts read-only. It reads `package.json`, `ios/App/Podfile`, `Podfile.lock` and `project.pbxproj`, then lists every plugin missing a `Package.swift` and every pod that is not a Capacitor plugin at all — Firebase, analytics SDKs, hand-added pods. Those need a vendor SPM package added to the App target in Xcode after the migration.

Then it picks a route. Most apps go through `npx cap spm-migration-assistant`, which keeps the existing Xcode project and its customizations. A fresh scaffold is the other option, for projects where `ios/` barely differs from the template. The skill tells you not to run a hybrid setup with a Podfile next to `CapApp-SPM`: the CLI treats a project as SPM only when `ios/App/CapApp-SPM/` exists, so renaming or deleting that folder quietly flips `npx cap sync` back to CocoaPods.

A few things bite later. `ios/App/CapApp-SPM/Package.swift` is regenerated on every `npx cap sync ios`, so put customizations in `capacitor.config.*` instead. A plugin ships only if its npm package root has a `Package.swift`; the rest are skipped with a warning and their native code is missing at runtime. Plain `.framework` files are not valid SPM binary targets — you need an `.xcframework`. Capacitor 8.x and 9.x are supported; on 6.x or 7.x the skill suggests upgrading first.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Cap-go/capgo-skills --skill cocoapods-to-spm -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Cap-go/capgo-skills --skill cocoapods-to-spm -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Cap-go/capgo-skills --skill cocoapods-to-spm -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Cap-go/capgo-skills cocoapods-to-spm
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Cap-go/capgo-skills --skill cocoapods-to-spm -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Cap-go/capgo-skills --path skills/cocoapods-to-spm
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Cap-go/capgo-skills --skill cocoapods-to-spm -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/Cap-go/capgo-skills/tree/HEAD/skills/cocoapods-to-spm/SKILL.md

## When to use it
- move an existing Capacitor iOS app off CocoaPods onto SPM
- find plugins that ship no `Package.swift` and decide what to do with them
- recover a `npx cap spm-migration-assistant` run that stopped halfway
- deal with the "plugins are not compatible with SPM" warning from `npx cap sync`
- get an app ready for Capacitor 9, where SPM is the default

## Example prompts
- migrate my Capacitor app from CocoaPods to SPM
- why does `npx cap sync` say a plugin is not compatible with SPM?
- prepare the ios project for Capacitor 9 and drop the Podfile

description: Migrates an existing Capacitor iOS app from CocoaPods to Swift Package Manager (SPM) before CocoaPods Trunk goes read-only (expected December 2, 2026). Use when the app still has ios/App/Podfile, Pods/, Podfile.lock or App.xcworkspace and the user wants CapApp-SPM, runs or recovers from `npx cap spm-migration-assistant`, needs debug.xcconfig / CAPACITOR_DEBUG wired up, sees "Some installed Capacitor plugins are not compatible with SPM" or "<plugin> does not have a Package.swift", or plans the Capacitor 9 upgrade where SPM is the default. Do not use for adding SPM support inside a plugin repository (use capacitor-plugin-spm-support), the UIScene lifecycle migration (use capacitor-uiscene-migration), full version upgrades (use capacitor-app-upgrades), or generic iOS build debugging (use debugging-capacitor).

# CocoaPods to Swift Package Manager Migration

Move a Capacitor iOS app from CocoaPods to SPM without losing native project customizations.

## When to Use

TRIGGER when:
- `ios/App/Podfile`, `Pods/`, `Podfile.lock`, or `App.xcworkspace` exists and the user wants SPM.
- User asks about `npx cap spm-migration-assistant`, `CapApp-SPM`, `debug.xcconfig`, or `--packagemanager SPM`.
- User worries about CocoaPods Trunk becoming read-only (expected December 2, 2026), or about pods that can no longer be published/updated.
- `npx cap sync` warns `Some installed Capacitor plugins are not compatible with SPM` or `<plugin id> does not have a Package.swift`.
- Upgrading to Capacitor 9 and wanting to drop CocoaPods at the same time.

Do not use:
- Adding `Package.swift` / `CAPBridgedPlugin` to a plugin you maintain -> `capacitor-plugin-spm-support`.
- SceneDelegate / UIScene adoption (Capacitor 8.5+, required by Xcode 27) -> `capacitor-uiscene-migration`.
- The Capacitor major upgrade itself -> `capacitor-app-upgrades`, `capacitor-app-upgrade-v8-to-v9`.
- Build or runtime failures unrelated to dependency management -> `debugging-capacitor`.

## Why Now

- CocoaPods Trunk is expected to become read-only on **December 2, 2026**. Existing pods keep resolving, but no new pod versions get published, so plugin fixes will increasingly ship SPM-only.
- Capacitor 8+ scaffolds new iOS projects with SPM by default. Upgrading Capacitor does **not** convert an existing CocoaPods app.
