"Switch must be exhaustive" warning, missing .unsupported cases

[neave]

Describe the bug
Xcode shows “Switch must be exhaustive” in PurchasesError.swift getStoreKitErrorInfoIfAny and StoreKitError+Extensions.swift, even though @unknown default is present. They need the '.unsupported' case.

1. Environment
   1. Platform:
   2. SDK version:
   3. StoreKit version:
      • StoreKit 1 (default on versions <5.0.0. Can be enabled in versions >=5.0.0 with .with(storeKitVersion: .storeKit1))
      • StoreKit 2 (default on versions >=5.0.0)
   4. OS version:
   5. Xcode version: 16.4
   6. Device and/or simulator:
      • Device
      • Simulator
   7. Environment:
      • Sandbox
      • TestFlight
      • Production
   8. How widespread is the issue. Percentage of devices affected.
2. Debug logs

Switch must be exhaustive

3. Steps to reproduce
   The compiler expects all enum cases to be explicitly handled, even with @unknown default.

4. Other information
   May require replacing @unknown default

5. Additional context
   Likely surfaced by stricter checks in recent Xcode versions or SDK updates.

👀 We've just linked this issue to our internal tracker and notified the team. Thank you for reporting, we're checking this out!

Hi, thanks for reporting this, we will take a look. Can you make sure that you are on our most recent SDK version 5.29.0 if you aren't already? Note that as this is a warning you should be able to still run your app and make purchases but let me know if this isn't the case.

Yes, this is using the most recent SDK version. And yes, it does compile as these are only warnings in Xcode (currently).

Hello, just checked with the latest XCode (26 RC1) and the latest Revenuecat 5.38.1, and this is still happening. It does compile, but warnings are adding a bit of noise, so a fix would be appreciated.
