Overview

I'm experiencing a persistent issue where my app uploads successfully to TestFlight and appears in App Store Connect, but internal testers (including myself) receive the following error when attempting to install: "Could not install xxxxxxxxx. The requested app is not available or doesn't exist." What works: The build archives and exports successfully via Xcode (local build, Release configuration) The IPA uploads to App Store Connect without errors via eas submit The build appears in TestFlight and passes processing I can add the build to my Internal Testing group Testers receive the TestFlight notification and can see the app What fails: When any tester taps "Install" or "Update," the download begins briefly, then fails with the "not available or doesn't exist" error This affects all internal testers on the account, not just one device Troubleshooting already completed: Verified code signing is correct: Release configuration uses CODE_SIGN_STYLE = Manual, CODE_SIGN_IDENTITY = "iPhone Distribution", with a valid App Store distribution provisioning profile (UUID: 39bc4c63-bc64-403a-a2a6-6737b3d33115) 2. Distribution certificate is valid: Serial 4838CD7571DE5361B98A5FB2F769F74D, not expired (expires 2027-04-16) 3. Regenerated provisioning profile via EAS credentials, removed stale profiles, and rebuilt — same result 4. Incremented build numbers correctly across multiple submissions (3004 → 3005 → 3006) 5. Previously resolved a signing misconfiguration (build 3005 was incorrectly signed with "Apple Development" instead of "iPhone Distribution" due to expo prebuild reverting settings) — this was corrected for build 3006, but the install error persists 6. Confirmed the build is not stuck in processing — it shows as ready for testing in App Store Connect 7. Tested on multiple devices running current iOS versions 8. Cleared TestFlight app cache and reinstalled TestFlight on test devices Why I believe this is a server-side issue: Multiple developers in the Apple Developer Forums have reported the identical symptom — valid builds that upload and process correctly but fail to install with this exact error message. In those cases, Apple Support resolved the issue on their end within 48 hours with no action required from the developer. The signing, provisioning, and build configuration were not the cause. This one is very specific to what I am dealing with https://developer.apple.com/forums/thread/778597 One developer stated you fixed it on your side, without any real reasoning which also leads me to believe this is not something I can fix on my end https://developer.apple.com/forums/thread/778597?answerId=884241022#884241022 I've exhausted all client-side troubleshooting and believe this may require intervention on Apple's side. Has anyone been able to fix this on their end and not only when App Development called? I went through tons of the feedback and tried it all and it doesn't seem to be fixed. It's been a month or so like this. I can't get any info on who to call. I sent in a report to feedback assistant and through app developer support

Hello, I created an app using the latest version of Xcode (16.2), and I'm having a problem testing this app on my iPhones. I created this app just like all the others I've made for my clients, including one on (03/24/25), but when I went to upload another App to App Store Connect on (03/26/25) I couldn't test it on my phone. Points to consider: The app runs perfectly on the Emulator. All my terms and agreements with Apple are up to date. I tried to download the apps through Testflight on 2 different devices, iPhone 7 Plus (iOS 15.8.1) and iPhone 15 Pro Max (iOS 18.3.2), and I was unsuccessful in neither attempt. I can send my app to the internal testers, but when I click download, the following message appears: Could not install [APP NAME]. The requested App is not available or doesn't exist. I imagine this problem is with Apple itself, I have already contacted support, but I need to resolve this urgently for my customers. Has anyone experienced this and resolved it?

I have an IME for Indic languages that I currently distribute outside of the Mac App Store because it does not seem to be supported. IMEs needs to be installed under /Library/Input Methods/ which I believe is not allowed for App Store apps. I could distribute it as an embedded helper app within my larger distribution app that I then install on start up - but I believe even that is not allowed. Is there a sanctioned way to distribute IMEs via the Mac App Store? The iOS store has support which I was able to use effectively.

After updating to macOS 26.5 Beta 3, all applications report no internet connection, even though the system is connected and internet works in browsers. App Store shows “No Internet Connection” Other apps (non-browser) also cannot connect to the internet Web browsers (Chrome) work normally Web browsers safari. not work Internet connectivity is confirmed (websites load correctly)

Hello Apple Developer Support, I would like to follow up regarding my Apple Developer Program enrollment. I have two order numbers: D004762197 (failed payment attempt on Tuesday, April 14, 2026) D004767639 (successful payment on Thursday, April 16, 2026, invoice received) Currently, my account is still showing "Pending" and asking to complete the purchase, even though the second payment was successful. It seems my account might still be linked to the failed order. Could you please help link the successful payment and activate my account? Thank you very much.

For a simple, resourceless cocoa apps I used to manually setup the application lifecycle (mimicking what's documented here: https://developer.apple.com/documentation/appkit/nsapplication), so my main.swift would look like: import Cocoa let delegate = SomeDelegate() _ = NSApplication.shared NSApp.delegate = delegate NSApp.run() This triggers a warning in Xcode 26.2: "Main actor-isolated conformance of SomeDelegate cannot be used in nonisolated context; this is an error in Swift 6 language mode". so what is the recommended way to refactor above so that it is Swift 6 compliant?

We are evaluating various AI frameworks to use within our code, and are hoping to use some of the build-in frameworks in macOS including CoreML and Vision. However, we need to use these frameworks in a background process (system extension) that has no user session attached to it. (To be pedantic, we'll be using an XPC service that is spawned by the system extension, but neither would have an associated user session). Saying the daemon-safe frameworks list has not been updated in a while is an understatement, but it's all we have to go on. CoreGraphics isn't even listed--back then it part of ApplicationServices (I think?) and ApplicationServices is a no go. Vision does use CoreGraphics symbols and data types so I have doubts. We do have a POC that uses both frameworks and they seem to function fine but obviously having something official is better. Any Apple engineers that can comment on this?

Apple's submission for FIPS140-3 (https://support.apple.com/guide/certifications/macos-security-certifications-apc35eb3dc4fa/web) has no mention of review for Intel or Intel T2 in FIPS Compliance on Tahoe. Is there any effort for this or will there be any effort? Has there any been any word that Intel as an architecture is completely out of the picture for FIPS140-3?

Hello, For the past few days I have been working on integrating a Crash Reporter called "BugSplat" to our macOS desktop app and it got me thinking, how do crash reporters work on macOS ? After days of trial and error (and claude's help) I managed to integrate it but with a different behavior than windows. On Windows: When the app crashes, the BugSplat crash report window opens and allows you to write your details and message to be sent with the crash report (along with a log file) On macOS: It displays the normal macOS' "App exit unexpectedly", to which I click dismiss. But then when I re-open the app the BugSplat crash report window appears. I asked claude if I can avoid the normal macOS dialog entirely, to which it replied: "This is by design — BugSplat macOS is a next-launch crash reporter, not an in-process one. Here's why that's intentional and unavoidable: When a process crashes (SIGSEGV, SIGBUS, etc.), macOS's ReportCrash daemon independently monitors all processes and shows the "quit unexpectedly" dialog — there's no API to suppress it. Meanwhile, BugSplat's Mach exception handler captures the crash data to disk. On the next launch, BugSplat finds that crash data and shows its dialog. This is the same model used by every macOS crash reporter (PLCrashReporter, Firebase Crashlytics on macOS, etc.). The process heap is in a corrupted state at crash time, so showing UI from inside the crashed process is unreliable." LLMs sometimes speak confidently even when they're wrong so that's why I'm asking: Is it really true that that's the normal behavior for every crash reporter? And is it really that huge of a change to overwrite the macOS dialog entirely ? Thank you in advance and sorry for the long paragraph

I would like to enable the app to persist a stable SIM identifier and compare it across app sessions so it can reliably detect when the user has changed SIM cards. When a SIM change is detected—especially while the device is on Wi-Fi—the app should trigger SIM-change handling (for example: refresh auth/session, reload account-specific data, and update feature availability). The implementation must be robust for: Dual-SIM and eSIM devices Temporary network unavailability or delayed carrier info Current challenge: On Wi-Fi, the existing hash can distinguish a different operator but cannot reliably detect a SIM-card-level change. We need a way to uniquely identify the SIM card itself, not just the operator.

I have a watchOS app with a connected iOS app using Swift and SwiftUI. The watchOS app should read heart rate date in the background using HKOberserQuery and enableBackgroundDelivery(), send the data to the iPhone app via WCSession. The iPhone app then sends the data to a Firebase project. The issue I am facing now it that the app with the HKObserverQuery works fine when the app is in the foreground, but when the app runs in the background, the observer query gets triggered for the first time (after one hour), but then always get terminated from the watchdog timeout with the following error message: CSLHandleBackgroundHealthKitQueryAction scene-create watchdog transgression: app<app.nanacare.nanacare.nanaCareHealthSync.watchkitapp((null))>:14451 exhausted real (wall clock) time allowance of 15.00 seconds I am using Xcode 16.3 on MacOS 15.4 The App is running on iOS 18.4 and watchOS 11.4 What is the reason for this this issue? I only do a simple SampleQuery to fetch the latest heart rate data inside the HKObserverQuery and then call the completionHandler. The query itself takes less than one second. Or is there a better approach to read continuously heart rate data from healthKit in the background on watchOS? I don't have an active workout session, and I don't need all heart rate data. Once every 15 minutes or so would be enough.

I am unable to update my apps because of Apple Developer License Agreement. I am told that I have to agree, yet I have agreed to every agreement available. When I log in my Developer Account there is no pending agreement either for free apps or Paid apps. The most recent one I agreed on April 6, 2026. I have logged out and in again multiple times. I tried to change the Account Holder to see if I get to agree on the agreement again but that did not help either. I have remained stuck and can't update any one of my apps since I get the error: "The Apple Developer Program License Agreement has been updated and needs to be reviewed. For more information, go to your account on the Apple Developer website." I have tried to reach out to Apple Support but no help was given. Can anyone please help? Much appreciated.

I am unable to receive an invite email on my apple account in order to accept and get access to testflight for testing apps

Has anyone got Xcode working with Opus 4.7? I have Claude Code running 4.7, but Xcode insists on running 4.6. Even working with Claude to try to configure Xcode doesn't work. Apparently Xcode does something that prevents using Opus 4.7. Any reason for this? Xcode has a really nice integration, but I guess It's bak to Terminal and Claude Code if I want to use the better Model. Anyone else got this working?

Just curious if there is anyway to expedite the FamilyControl entitlement. I have seen few people stuck in this step for few days. I submit mine on the 4/18, and my Case ID: 102874096254 Just want to see if I can see any estimate time for my request. Thanks, Jing

Dear Apple Team, I need your help resolving an issue that Apple Support has been unable to fix for over two months. Since February 2026, the Apple Developer app has rejected my identity verification every time I attempt to enroll in the Apple Developer Program. I have reached out to Apple Support repeatedly — by email and by phone — and have received no explanation for the failure and no workable solution. My case numbers from these interactions are: 102818147247 102838793176 102842518632 To be direct: I'm not intend to be aggressive, I just exhausted every normal support channel available to me. The responses I have received so far have been polite but ultimately ineffective — the same suggestions are repeated, and no one has investigated the underlying cause. This is not a minor inconvenience. I run PlayPatch Tech as an small team with iOS apps that are blocked from App Store submission entirely because of this enrollment failure. Every week this remains unresolved is a week of lost business. Relevant details: Enrollment type: Organization Device: iPad Pro & iPadOS 26.3.1(a) Government ID used: China ID Card Timeline: February 2026 – present Support contacts: Email 8 times, Call 6 times, they tried their best, but nothing worked. What I need: Someone with the authority and access to diagnose why verification is failing for my account specifically. An alternative verification path if the app-based method doesn't work. I would appreciate a response within 5 business days. I am available at any time and willing to provide whatever documentation is required. Regards, Neo PlayPatch Tech

Hi Team, I recently purchased a one-year Apple Developer Program membership but have not received a membership ID. Could you help me locate the details? I would also appreciate guidance on the steps to publish my app to the App Store from my local Mac.

Hi, I have some scenario in which I need to reportIncoming to CallKit with same UUID 2 times. So I just need to know that, it will cause an issue of CallKit or with application.

Hey my app subscriptions are currently in review whilst my app has been approved 2 times, i need this to be approved to start marketing it.
