Build fails with Xcode 26.3+ — TestStoreProduct, TestStoreProductDiscount, TestStoreTransaction not found in scope

Describe the bug
Building with Xcode 26.3 or 26.4 fails due to Swift compilation errors in PurchasesHybridCommon. The iOS 26 SDK appears to have removed or renamed StoreKit types and changed the signature of Product.PurchaseOption. EAS builds fail on EAS servers and on local builds.

Errors (from RevenueCat/Sources/Purchasing/OfferingsManager.swift)

  cannot find 'TestStoreProduct' in scope
  cannot find type 'TestStoreProductDiscount' in scope
  cannot find type 'TestStoreProduct' in scope
  cannot find 'TestStoreTransaction' in scope
  cannot convert value of type '[String : String]?' to expected argument type
  'Set<Product.PurchaseOption>'
  extra argument 'completion' in call
  type of expression is ambiguous without a type annotation

1. Platform: iOS
2. SDK version: 10.3.0
3. OS version: iOS 26
4. Xcode/Android Studio version: Xcode 26.3 (local), Xcode 26.4 (EAS cloud build)
5. React Native version: 0.81.5
6. SDK installation: CocoaPods 1.16.2

Thanks for the detailed report, @cydalby. The logs are really helpful! 🙏

Every error in your log is at a use site of TestStoreProduct, TestStoreProductDiscount, and TestStoreTransaction. I see no errors inside the files that define them. Those three are the only SDK source files whose names contain "Test", and they're unconditionally compiled production code (the Test Store relies on them).

That "cannot find ... in scope" pattern where there are no errors in the defining files could mean those files aren't being compiled at all, i.e. something in the build is excluding them. Could be an EXCLUDED_SOURCE_FILE_NAMES = *Test* (or maybe a filter catching the Test Data folder?). The Set<Product.PurchaseOption> / extra argument 'completion' errors could just be cascades: once TestStoreProduct is unresolved, the purchase(simulatedStoreProduct:...) overload becomes invalid and the call mis-resolves to a different purchase overload. This is just a hypothesis though 😅

Could you check the following in your app project?

• Any EXCLUDED_SOURCE_FILE_NAMES / *Test* pattern, or a post_install hook in your Podfile, or an EAS prebuild/config step that strips "test" files from release builds.
• Whether TestStoreProduct.swift appears in the RevenueCat pod target's Compile Sources.

If you don't find anything like that, perhaps you could share a minimal project that reproduces the issue? That would let us confirm it on our side. Thanks again!
