We are dealing with a launch-time crash that happens every time in Apple’s review environment, but does not occur in any of our local or TestFlight testing.
Case-ID: 15374981
Device in Review: iPad Air (5th generation)
OS in Review: iPadOS 18.6
Build Environment: Xcode 15.x → Archive → Export for App Store Connect
Deployment Target: iOS 14.0+
Architecture: arm64
What Happens
In Apple’s review environment: app launches → no UI → immediate crash.
We have 8 crash logs from App Review — all with identical stack signatures.
In our testing: the same build runs without issue on:
iPad Air (5th gen) – iPadOS 18.5, 18.6
iPad Pro 11" – iPadOS 18.5, 18.6
Multiple iPhone models – iOS 17.x / 18.x
Crash Log Signature (main thread)

Tested across multiple devices and OS versions — no local repro.
Request
Looking for:
Known iPadOS 18.6 launch-time regressions on iPad Air 5th Gen.
Any Apple-internal tooling/config differences in the review environment that could trigger Address size fault at launch.
Guidance on how to replicate the review environment for debugging.
