The Exact inAppPurchases Fix That Unblocked My Last 4 Apple Rejections
No PDF. No email course. Just the relationship string change that actually works.
Who this is for: Indie iOS devs hitting IAP 2.1(b) "App Completeness" rejection on a paid app. If Apple sent you a rejection email mentioning inAppPurchases relationship — this is the fix.
What I Actually Fixed (Real Apps)
AltitudeNowPro 鈥?v1.0.2 rejected (IAP 2.1(b)) 鈫?v1.0.3 APPROVED after inAppPurchasesV2 fix + new binary
PromptVaultPro 鈥?rejected twice 鈫?approved same day after relationship string fix
NewDaysUntil 鈥?rejected once 鈫?approved after IAP config update
Same fix. Same process. Worked on all 3.
The Fix (30 seconds)
In App Store Connect — your app — In-App Purchases — relationship string:
Change: inAppPurchases
To: inAppPurchasesV2
That's it. Save, then upload a new binary (or request Apple to re-review if you already have a clean build).
The Hidden Trap
If you changed the relationship string but Apple still rejected — it's probably because you uploaded the fix in the same binary that triggered the rejection. Apple will not re-review the same build ID with the fix applied.
Bump the build number (e.g., 1.0.0 — 1.0.1)
Upload the new binary to ASC
Submit for review again
Or ask Apple to re-review the same build after the IAP fix (sometimes works)
3-Step Fix Process
1
Find the IAP in ASC — App Store Connect — your app — In-App Purchases. Click the IAP that is being rejected. Look at the relationship string field.
2
Check the relationship string — If it says inAppPurchases, change it to inAppPurchasesV2. If it already says inAppPurchasesV2 — the problem is elsewhere.
3
Upload new build + re-submit — After saving the IAP change, bump your build number and upload a new binary. The relationship string change alone will not trigger re-review of the same binary.

5-Point IAP Rejection Checklist
1
Relationship string — inAppPurchases vs inAppPurchasesV2. Change to V2 if rejected.
2
New binary required — Same build ID will not re-trigger review. Bump build number + upload new binary.
3
Both IAPs present — If both inAppPurchases AND inAppPurchasesV2 exist, remove the old one (keep V2 only).
4
Product ID consistency — Must match exactly in 3 places: ASC IAP ID, StoreKit file product ID, Xcode Product ID.
5
ASC API verify — Call GET /v1/apps/{bundleId}/inAppPurchases/{iad}/relationship to check what Apple actually sees.
