Problem
iCloud Sync between the iPhone and Mac apps reports success on both devices but moves no data. Logs show the Mac pulling
0 changedand both sides logging "Sync completed successfully".Root cause
The Mac app pins
com.apple.developer.icloud-container-environment = Production(added in5dcb668c). The iOS app's entitlements never got that key. Per Apple's docs, a development-signed build with the key absent defaults to the Development CloudKit environment, while the Mac (and any TestFlight/App Store build) uses Production.Same Apple ID, same container
iCloud.com.TablePro, same zoneTableProSync, but two separate backing databases. Each device creates the zone, pushes, and pulls successfully against its own environment, so each reports success while nothing crosses between Development and Production.Fix
Add the missing key to the iOS entitlements, mirroring the Mac. App Store/TestFlight builds are unaffected (they were always Production); development iPhone builds now use Production too.
Test
EntitlementsEnvironmentParityTestsparses both entitlement plists and asserts each pins Production. It fails if either app drifts. Runs without CloudKit or a network. Passing locally.Migration note
After updating, reinstall the iOS build. If the iPhone still shows nothing, toggle iCloud Sync off/on once on the Mac to force-push existing data into Production.
