Increased StoreKit errors “Unable to Complete Request”
Since January 28, 2026, we’ve noticed an increase in StoreKit-related errors during purchase flows. Specifically, we’re seeing a spike in errors reported as “Unable to Complete Request”, categorized as unknown StoreKit errors. This correlates with a noticeable drop in the overall purchase success rate. A few observations: The issue is not limited to the latest app version, it also affects older versions. It appears to occur only on iOS 17+. The impact seems country-specific: some regions are affected more heavily, while others show no significant change compared to previous days. At the moment, there are no related incidents reported on Apple’s System Status page. Given these symptoms, this looks like a potential StoreKit / Apple API issue, but we haven’t found any official confirmation yet. Has anyone else observed similar StoreKit behavior recently on iOS 17+? Any insights or known issues would be greatly appreciated.

On-Demand Resources with Initial Install Tags Are Frequently Unavailable at First Launch
Hello, Because our app package size is relatively large, part of our resources needs to be delivered through Apple-hosted asset packs. If we use the Background Assets framework to download these Apple-hosted packs, our app would only be able to support devices running iOS 26 or later. To maintain compatibility with a broader range of iOS versions, we chose to use iOS On-Demand Resources instead. However, during actual use, we found that even when these packs are marked with the initial install tag, there is still a fairly high probability (around 40%) that they are not available on the first screen after the app is launched for the first time. When we try to access them through conditionallyBeginAccessingResourcesWithCompletionHandler, the resources are unavailable, which forces us to download them again. During testing, we added event tracking and found that out of 22 users who downloaded the app, 9 had to re-download these resource packs on first launch. Each of these packs marked with the

Unable to install Dev App via Firebase
Hi there, I'm at a loss as to how to resolve this so hoping I can get some help/ideas here. Issue: We currently have two users who are unable to install our development iOS app. We sign the app as normal during the build process and upload it to firebase for distribution. Both of these users and their devices have been able to use this system previously, all our other dev users and devices are also still working but two of them receive an this app cannot be installed because it's integrity could not be verified error. What I have done to resolve: Check device UDIDs are both registered in apple developer portal Checked that the development profile has those devices included Checked that the development certificate is valid, this cert is being used with a different development app that isn't having this issue Restored the device disabled and reenabled the developer mode reinstalled the firebase distribution profile recreated the developer provisioning profile All of the above have not resolved the issu

Reply to Unable to install Dev App via Firebase
Update: We installed a build from a month or so ago and this has now unlocked both phones to be able to use newer builds. While triaging we noticed that although the devices were registered in Firebase already they were being seen as new devices. The only thing we can think of as being the issue is that the Apple Developer agreement when the apps that broke the devices were built had not been accepted. This meant we were unable to add/remove devices, change profiles etc. This has led us to believe it invalidated the profile during that time and by installing the app it somehow broke how the devices were validated until we accepted the agreement and installed a previously known good app. Nothing else changed during the time period that this occurred. Anyway hope this might help someone else who ends up in this state

My App stuck in "Waiting for Review" two week
Hello everyone, My app (ID: 6756186616) was submitted on Mar 15, 2026, and has been stuck in Waiting for Review status for over 17 days. I contacted Developer Support (case #20000111565861) and received confirmation that it's proceeding normally, but no update since. On average, Apple reviews 90 percent of apps within 24 hours. However, there might be cases that need more review time, but mine exceeds two week. Any recent experiences with long queues? Thanks!

Apple Watch Missing Developer Mode Option
I have an iPhone 14 running iOS 16.1 and my series 5 watch running watchOS 9.1. I was able to turn on Developer Mode on the phone by going to Settings--> Privacy & Security --> Developer Mode. On the watch however (I'm doing this directly on the watch and not on the watch app on the phone) once I'm in Privacy & Security, there is no option to select Developer Mode. How do I get my watch in Developer Mode in order to get a successful build in xCode?

Reply to Is anyone working on jax-metal?
Still broken as of early 2026 in my testing. For JAX workloads on Apple Silicon I've moved to MLX entirely — the API is different but the Metal backend actually works and gets regular updates. For anything that must stay in JAX, CPU fallback is unfortunately the only reliable path on macOS right now.

Reply to TESTFLIGHT: The requested app is not available or doesn t exist
this poor service gave me the worst experience and I can clearly see watching this thread how deep Apple suсks. No solution, no help, no reaction, just paying developers without any support for months.

In case anyone else has the issue with the Apple Watch not showing, I went through everything above but finally saw in Xcode...settings...apple account that I had to log into to the apple portal to accept the new terms. Once I did that it seemed to work.
