# Add Swift Package Manager Support to a Capacitor Plugin

Add SPM support to an existing Capacitor plugin so it can be consumed without CocoaPods.

## When to Use This Skill

- User wants a plugin to work through Xcode's package manager

- User is converting an existing iOS plugin from Obj-C bridge files to bridged Swift registration

- User needs the plugin package manifest and file exports updated for SPM

## Procedures

### Step 1: Gather Plugin Information

Read these files in the plugin root:

- `package.json`

- the `.podspec`

- the main Swift plugin class under `ios/`

Record:

- the package name

- the pod name

- the iOS deployment target

- the plugin class name

- the JavaScript plugin name

- all exposed plugin methods

- any third-party CocoaPods dependencies that also need SPM equivalents

### Step 2: Create `Package.swift`

Add a `Package.swift` manifest that:

- declares the plugin package name

- sets the iOS minimum version

- points the target at the plugin's iOS source directory

- depends on the Capacitor Swift package support package used by the project

- adds any resolved third-party SPM packages

Keep the target structure aligned with the actual plugin source tree.

### Step 3: Convert the Swift Plugin Class

Update the plugin class to conform to `CAPBridgedPlugin`.

Add the bridge properties at the top of the class:

- `identifier`

- `jsName`

- `pluginMethods`

Preserve each method name and return type exactly as the plugin already exposes them.

### Step 4: Remove Objective-C Bridge Files

Delete the old bridge header and implementation files once the Swift bridge is in place.

Then clean the Xcode project file so it no longer references them.

### Step 5: Update Package Metadata

Update the plugin package manifest so it exports:

- the iOS sources

- the podspec

- `Package.swift`

Add an iOS SPM install command if the project maintains script helpers.

### Step 6: Verify

- Run the plugin's install and build checks:

+ Use the repository's existing package manager for dependency install.

- ```bash

- bun install

- bunx cap sync

- ```

+ Run Capacitor sync from the example or test app directory that contains `capacitor.config.*`.

+ Use the repository's package manager install command, then `cd example-app` and run the matching Capacitor sync command from there.

- Then build the plugin's example or test app.

+ Then build that same example or test app.

## Error Handling

- - If the Swift package resolver fails, check the target path and package dependency names first.

- - If the bridged plugin fails to register, verify the class name, `identifier`, and `jsName` all match the plugin's exported API.

- - If the plugin has unsupported CocoaPods dependencies, keep CocoaPods for those dependencies or replace them with SPM-compatible equivalents before removing the old bridge.

+ - For Swift package resolver failures, check the target path and package dependency names first.

+ - For bridged plugin registration failures, verify the class name, `identifier`, and `jsName` match the exported API.

+ - For unsupported CocoaPods dependencies, keep CocoaPods for those dependencies or replace them with SPM-compatible equivalents before removing the old bridge.
