Hello,
I’m investigating subscription product discovery in my iOS app, BiteTempo. StoreKit 2 completes the product request successfully but returns an empty array for both auto-renewable subscriptions.
The issue occurs on a physical iPhone running through Xcode and also in TestFlight.
App and products
Bundle ID: shehan.NouriJournal
App version: 1.0 (4)
Monthly: shehan.NouriJournal.plus.monthly
Annual: shehan.NouriJournal.plus.annual
Reported storefront: USA
Device system version reported in diagnostics: 26.6.1 (23G83)
Reproduction
Run the app on a physical iPhone through Xcode with StoreKit Configuration set to None.
Open the subscription paywall.
Request both products using Product.products(for:).
Inspect the returned array immediately after the awaited call, before filtering.
At that breakpoint, returnedProducts contains 0 values.
The empty result is not created by application filtering or by converting a caught error into an empty array. Errors are reported separately.
Diagnostic output from the Xcode device run
Date: 2026-09-26T10:06:24Z
App: shehan.NouriJournal 1.0 (4)
Storefront: USA
Requested: shehan.NouriJournal.plus.monthly, shehan.NouriJournal.plus.annual
Returned: 0
Products:
Lookup: completed
I also see unavailable plans in TestFlight, although the diagnostic output above is specifically from the Xcode device run.
Configuration checked
Product IDs match App Store Connect exactly.
Both subscriptions have pricing and all-country availability.
Both products and their subscription group have English (U.S.) localization.
Paid Apps Agreement is Active.
Other apps under my developer account have working live subscriptions.
Debug and Release use the same bundle identifier and signing team.
No local StoreKit configuration file is selected.
A Sandbox Apple Account is signed in on the test device.
These are the first subscriptions for this app and have not yet been submitted for review. I have retried after completing the missing localization, but the result remains empty.
The failure occurs during product discovery, before any purchase or server-side transaction verification.
What additional checks or diagnostics would help distinguish an app/signing configuration issue from a sandbox product-catalog availability issue? Is there any additional product state or configuration required for these subscriptions to appear in sandbox?
I have also submitted a support request to Apple and can provide a minimal reproduction project through the appropriate support channel.
Thank you.
