Adds Swift Package Manager support to an existing Capacitor plugin repository so apps using CapApp-SPM can consume it after CocoaPods Trunk goes read-only (expected December 2, 2026). Covers root Package.swift naming rules the Capacitor CLI depends on, CAPBridgedPlugin conversion (identifier, jsName, pluginMethods), removing the ObjC CAP_PLUGIN bridge (.m/.h), Sources/Tests layout, podspec and package.json files updates, third-party pod to SPM dependency mapping…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Add Swift Package Manager Support to a Capacitor Plugin

Make a plugin installable in SPM-based Capacitor apps while keeping its podspec for CocoaPods apps.

## When to Use

TRIGGER when:
- A plugin repo has `ios/Plugin/*.swift` + `*.m`/`*.h` with `CAP_PLUGIN(...)` and no root `Package.swift`.
- An app's `npx cap sync ios` prints `<plugin id> does not have a Package.swift` for a plugin the user maintains.
- A plugin works with CocoaPods but JS gets `"X" plugin is not implemented on ios` in SPM apps.
- Preparing a plugin for Capacitor 9 / CocoaPods Trunk read-only.

Do not use:
- App-side CocoaPods removal -> `cocoapods-to-spm`.
- Capacitor major bumps of a plugin -> `capacitor-plugin-upgrades`, `capacitor-plugin-upgrade-v8-to-v9`.
- Android-only plugin work, or non-Capacitor (pure Cordova, React Native) plugins.

## Rules the CLI Enforces (non-obvious)

- `Package.swift` must be at the **npm package root** (next to `package.json`), not under `ios/`. The app CLI only checks `<plugin root>/Package.swift`.

How to install

The exact contents, by fingerprint

mdr add cap-go/capgo-skills/capacitor-plugin-spm-support@sha256:0a3141fca9ad3bc5

The line at the top of this page pins the label git:20261011.86834d4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
