We are promoting an app bundle. Can we append a campaign tracking code to it?

I’m updating an old app which uses StoreKit and hosted in-app purchases (multimedia add-ons). The original .pkgs are missing and the only known place they exist intact is on Apple’s servers. The app is able to download and install the IAPs. Is there anyway to save them to the local device?

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) Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Subtype: KERN_INVALID_ADDRESS Termination Reason: Address size fault Crashed Thread: com.apple.main-thread 0 libsystem_kernel.dylib mach_msg2_trap + 8 1 libsystem_kernel.dylib mach_msg_overwrite + 428 2 CoreFoundation __CFRunLoopServiceMachPort + 160 3 CoreFoundation __CFRunLoopRun + 1208 4 CoreFoundation CFRunLoopRunSpecific + 572 5 UIKitCore -[UIApplication _run] + … 6 UIKitCore UIApplicationMain + … libobjc-trampolines.dylib appears in several traces immediately before the crash.

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.

I see this marketing program all the time on e-commerce websites, but not so much in apps. In my case, we sell a $5 app with an additional premium upgrade IAP. We're trying to promote referrals to the premium upgrade IAP. Here's how I think it would work: customer A signs up to IAP referral program inside app customer A gets sharable code/url customer A sends code to customer B customer B downloads app, purchases IAP using code customer A receives reward 1) Even though this program doesn't incentivize the main download of the app--but rather just the in-app purchase-- would it still violate Apple's rules? 2) Is it only a problem because the referral program ORIGINATED within the app? In other words, if we launched this program exclusively on our website, would Apple take issue with it? Thanks
