# Issues when compiling or archiving

## iOS

** 1. Clean derived data:** in Xcode, go to Product -> Clean Build Data. ** 2. Make sure Swift support is enabled in the project:** check that Swift Language Version is defined as at least "Swift 5" in Build Settings for your target.  ** 3. Make sure that the deployment target is set correctly:** it should be set to `9.0` or newer for iOS or tvOS, `10.12` or newer for macOS and `6.2` or newer for watchOS. ** 4. Check the Swift version: ** Check that the value for [`SWIFT_VERSION` isn't overridden by the `Podfile`, if you have one.](🔗). ** 5. Enable Swift support: ** If you're getting errors when compiling Swift files after this, try adding a single, empty Swift file to the project.

### If you're using CocoaPods:

**1. Make sure you're using the latest version of CocoaPods.** You can see your version by running `pod --version`, and find the [latest version here](🔗). ** 2. Re-install pods:** run `pod deintegrate` and then `pod install`, then try running / archiving the project again. ** 3. Make sure that the deployment target is set correctly:** it should be set to `9.0` or newer for iOS or tvOS, `10.12` or newer for macOS and `6.2` or newer for watchOS. The requirements might be higher if you're using other frameworks, such as React-Native. You should check this value both in the `Podfile`, and by going into the Project settings, then select the target, and look for the value in the general tab:  ** 4. Check the Swift version: ** Check that the value for [`SWIFT_VERSION` isn't overridden by the `Podfile`](🔗). ** 5. Enable Swift support: ** If you're getting errors when compiling Swift files after this, try adding a single, empty Swift file to the project. ** 6. If that _still_ doesn't work, then make sure that Swift is added to your Library Search Paths. Go to Build Settings, then look for Library Search Paths, and add `$(SDKROOT)/usr/lib/swift` as the **first** item on the list if it's not present.

### If you're using Carthage:

** 1. ** Make sure you're using the latest version of Carthage. ** 2. ** If you're using XCFrameworks with Carthage, make sure you [follow our installation guide](🔗).

## Flutter

** 1. ** Upgrade to the latest version of [purchases-flutter](🔗) ** 2. ** Upgrade to the [latest version of Flutter](🔗) ** 3. ** Run `pub cache clean` ** 4 **. Follow the [troubleshooting steps for iOS](🔗). ** 5. ** [Check that Flutter doesn't override the minimum deployment version on iOS](🔗)

## React-Native

** 1. ** Upgrade to the latest version of [react-native-purchases](🔗) ** 2. ** Upgrade to the [latest version of React-Native](🔗). ** 3. ** If you're setting `BUILD_LIBRARY_FOR_DISTRIBUTION` in your Podfile, ensure RevenueCat's targets are excluded.


** 4. ** Follow the [troubleshooting steps for iOS](🔗).
