If Xcode can't resolve Swift packages in an app that uses RevenueCat's React Native, Expo, Flutter, Capacitor, Cordova, or Unity SDK, use this article to find and remove the extra copy of the RevenueCat iOS SDK.

These SDKs include the RevenueCat iOS SDK through the `purchases-hybrid-common` package, which depends on `purchases-ios-spm` at the exact version each SDK release is tested with. The errors below appear when your project, or another package in it, also adds the RevenueCat iOS SDK.

## Xcode reports multiple similar targets in purchases-ios-spm and purchases-ios

Xcode fails to resolve packages with this error:

```text
multiple similar targets 'ReceiptParser', 'RevenueCat', 'RevenueCatUI' and 1 others appear in package 'purchases-ios-spm' and 'purchases-ios'
```

`purchases-ios` and `purchases-ios-spm` are two repositories that contain the same RevenueCat iOS SDK. Swift Package Manager treats them as different packages, so the same targets appear twice.

### Cause: You added purchases-ios to your project

In Xcode, select your project in the Project navigator and open the **Package Dependencies** tab. If it lists `purchases-ios`, your project depends on it directly. Select `purchases-ios` and click **–** to remove it.

Your native code can still use RevenueCat without it: add `import RevenueCat` to your Swift files. If you installed the UI package, `import RevenueCatUI` works the same way. Your RevenueCat SDK already links these modules.

### Cause: Another package depends on purchases-ios

If your project doesn't list `purchases-ios` directly, another package depends on it. Check the `Package.swift` of the packages listed under **Package Dependencies** in the Project navigator, and ask that package's maintainer to depend on `purchases-ios-spm.git` instead.

Until the package changes, add a [Swift Package Manager mirror](https://github.com/swiftlang/swift-evolution/blob/main/proposals/0219-package-manager-dependency-mirroring.md) so Xcode fetches `purchases-ios-spm` wherever a package asks for `purchases-ios`:

1. Create a file named `mirrors.json` with this content:

   ```json
   {
     "object": [
       {
         "original": "https://github.com/RevenueCat/purchases-ios",
         "mirror": "https://github.com/RevenueCat/purchases-ios-spm"
       },
       {
         "original": "https://github.com/RevenueCat/purchases-ios.git",
         "mirror": "https://github.com/RevenueCat/purchases-ios-spm"
       }
     ],
     "version": 1
   }
   ```

   Keep both entries. Swift Package Manager matches each URL as the package writes it, with or without `.git`.

2. Save the file in the workspace or project you open in Xcode:

   - Workspace: `YourApp.xcworkspace/xcshareddata/swiftpm/configuration/mirrors.json`
   - Project: `YourApp.xcodeproj/project.xcworkspace/xcshareddata/swiftpm/configuration/mirrors.json`

   Xcode ignores the project's file when you open the workspace. If your team or CI opens both, save the file in both locations.

3. Reopen the project, then choose **File > Packages > Resolve Package Versions**.

4. Commit `mirrors.json` so teammates and CI use the same mirror.

The mirror applies to every package in your project. `purchases-ios-spm` only publishes releases, so a package that requires `purchases-ios` at a branch or commit can't resolve through the mirror. Its version requirement must also allow the version your RevenueCat SDK uses.

## Xcode can't resolve a purchases-ios-spm version

Xcode fails to resolve packages with an error like this one, showing the versions in your project:

```text
Dependencies could not be resolved because root depends on 'purchases-ios-spm' 5.98.0.
'purchases-ios-spm' 5.99.0 is required because 'purchases-hybrid-common' 20.1.0 depends on 'purchases-ios-spm' 5.99.0 and root depends on 'purchases-hybrid-common' 20.1.0.
```

### Cause: Your project requires a different RevenueCat iOS SDK version

Each release of a RevenueCat cross-platform SDK requires one exact version of `purchases-ios-spm`. If your project's **Package Dependencies** tab lists `purchases-ios-spm`, remove it. Your RevenueCat SDK still includes it, and your native code can still `import RevenueCat`.

If you added a mirror for another package, check that package's version requirement for `purchases-ios` instead.
