Reply to Universal Links and Cloud-testing platforms
Thank you for the quick response and for the clarification on how iOS enforces AASA validation, that context is very helpful. To answer your question: our cloud-based device testing environment is a third-party device farm that runs automated UI tests against real iOS devices hosted in their infrastructure, BrowserStack. In order to install our app on their devices, their platform re-signs the app using their own provisioning profile, which is where the Associated Domains entitlement is lost. We fully understand that this is a security boundary by design, we are not looking to bypass AASA validation in production. Our concern is specifically scoped to pre-production testing: we need a way to validate our authentication flow end-to-end (including the Universal Link redirect back into the app) in an automated, cloud-hosted environment before shipping to production. Given your confirmation that there is no native provisioning flag to accommodate this, we have a follow-up question: Short of the

Concerns about App Review risk for vendor-specific device protocol that reuses Matter-derived components internally
My team is evaluating an iOS companion app for our own network-connected device, and we want to understand whether the planned architecture would likely create an App Review problem under Guideline 2.5.17. Our situation is: We are building our own device and our own companion app. We do not intend to market the device as a Matter-certified device initially. We do not intend to support Apple Home or broad third-party Matter ecosystem interoperability in the first release. We are under a tight schedule and are considering reusing Matter/CSA-derived libraries, data models, and protocol concepts internally to reduce engineering effort and move faster toward eventual certification. Our current understanding is that there are already many iOS apps that communicate with LAN-connected devices using proprietary protocols, so our initial assumption is that a vendor-specific local-network device workflow should generally be acceptable. The point we are trying to clarify is whether that changes if the i

App Review 2.1(b): paywall present in build but disabled — can it block review? What’s the best response?
Hello everyone, I’m submitting an iOS app to App Review and received Guideline 2.1(b) – Information Needed. Apple says it appears the app may access or include paid digital content/subscriptions and they want details about the business model. In my project, a paywall / premium UI exists in the codebase, and subscription products are configured in App Store Connect for a future release, but in the build currently submitted: The paywall is disabled (not reachable through any UI flow / feature flags are off). There is no purchase flow (no way to subscribe in-app). There is no external purchase (no website/Stripe/etc.). Users cannot access any previously purchased subscriptions (no entitlement access / restore not exposed). Questions: Can the mere presence of a paywall screen / IAP-related code in the binary (even if disabled/unreachable) block App Review or trigger repeated 2.1(b) requests? Is it recommended to remove paywall/IAP code entirely from the review build if it’s not used yet, or is a clear ex

Reply to Xcode 26.2 Can't download
Thanks for the post, and welcome to Xcode and iOS development! To download iOS Simulators for Xcode 26.2, use the Components settings within Xcode. Navigate to Xcode > Settings, from the menu bar, then select the Components tab. The Platform Support section displays the latest available platform and Simulator runtimes. To obtain a previously released Simulator runtime, click the Add button (+) in the lower-left corner, select a platform, and then choose the desired version. Click Download & Install to proceed. Xcode 26.2 includes SDKs for iOS 26.2, iPadOS 26.2, macOS 26.2, tvOS 26.2, visionOS 26.2, and watchOS 26.2. These SDKs are necessary for developing and testing applications for their respective platforms. There are other methods to download simulators but if you are in Xcode, will be easier if you just use that tool to download the simulators as they should be downloaded after installation. I would also recommend to update Xcode to the latest release. More information h

Reply to macOS 26.4 Dev Beta 2 Install Fails
I had the same issue on a M1-Max Studio (with installations of 26.4 beta 3, beta 4, and the RC). I finally solved it and reported the following as a appendix to FB22153797: SUCCESS!! First, what didn’t work — I booted in Safe Mode and tried to install Tahoe 26.4. This failed just as reported above. Then, I DEINSTALLED the F-Secure security suite (which came with my Spectrum Business ISP account). Then attempted the installation (in NORMAL mode, not Safe Mode). The installation worked. So it is clear that the install problem was related to something that F-Secure did to my system that was undone by de-installation.

App rejected under Guideline 2.1(a) - App Completeness. Seeking advice!
Hello everyone, I recently submitted my iOS app for review, but it was unfortunately rejected under Guideline 2.1(a) - Performance - App Completeness. For context, my app is a healthcare application built with Ionic. According to the App Review team's message, they found the app to be incomplete. They stated they were unable to review the app because they couldn't get past the login screen. The Root Cause: Upon investigating, we discovered the issue is related to IP Geo-blocking. Because the app handles sensitive healthcare data, our API provider strictly blocks all network traffic originating from outside of Italy to legally comply with European GDPR regulations. Since the App Review team tests from the US, their requests are being entirely blocked by the firewall, causing the login to fail and the app to look broken on their end. What I have verified so far: I have provided valid demo account credentials in the App Store Connect App Review Information section. I have tested the app thoroughly on ph

Xcode 26.2 Can't download
Help please! I'm new to Xcode and my Mac is a 2021 MacBook Pro. I've downloaded Xcode recently (version 26.2) and wanted to preview and test my first App. But somehow, I just can't download the iOS simulator. People tell me that I can download resources from developer.apple.com, but I only found the iOS_18.2_runtime.dmg. I downloaded and installed the iOS 18.2 version but Xcode still requires to download the iOS 26.2 simulator. I don't know why and how to fix this problem. Please help!

Reply to Crash on App Clip Subtitle Focus
Thanks for the post. I don’t think you have provided much information to be able to help you. Can you provide a focused sample of how you use App Clips? Are you using Xcode, can you create a new sample project that reproduces the issue using the steps below? App Clips are built as a separate target within your existing iOS app project. Open your project in Xcode. Go to File > New > Target. Select App Clip under the iOS tab. Name your App Clip and ensure it is embedded in your main application target. App Clips rely heavily on Universal Links to securely verify the relationship between your website and your app. Add the Associated Domains capability to both your main app target and your App Clip target. Add your domain using the appclips: prefix. Example: appclips:example.com Update the apple-app-site-association (AASA) file on your web server to include an appclips dictionary. { appclips: { apps: [..Clip] } } Please follow this great documentation: https://developer.apple.com/design/hu

Reply to Universal Links and Cloud-testing platforms
Thanks so much with the post. Can I ask you what’s your “cloud-based device testing environment”? Because Universal Links rely on cryptographic trust between the app and the web server, the re-signing process inherently could breaks this trust? The platform signs the app with their own provisioning profile, which does not contain your com.apple.developer.associated-domains entitlement? Apple's security model intentionally prevents unauthorized third parties from claiming your domain. Therefore, there is no native Apple provisioning flag that tells iOS to ignore AASA validation for re-signed builds. Can you provide more details? However, please understand that Universal Links will only work on physical devices with the entitlement. Albert Pascual

Universal Links and Cloud-testing platforms
Hi Apple Developer Support, We are reaching out to request guidance on a testing constraint we have encountered related to iOS Universal Links and Associated Domains entitlements. As part of aligning with updated recommendations from our authentication provider, we have transitioned our mobile apps to use HTTPS redirect callbacks (Universal Links) instead of custom URI schemes. This works as expected in production and on real physical devices. However, we are encountering a significant issue in our cloud-based device testing environment. When our testing platform re-signs the app to run it on their infrastructure, the re-signing process strips the Associated Domains entitlement from the app bundle. As a result, iOS no longer honors our Universal Links, which breaks the authentication redirect flow — the callback cannot route back into the app after the user authenticates. We have identified a potential workaround that would involve disabling app re-signing in the testing platform, but this r

iOS 26.4: Receipt of previous transaction is returned
Hi, We are facing issue with purchases on iOS 26.4. The app store receipt received is from previous transaction leading to receipt validation failures. There are some purchase success observed for pending transactions but success rate for pending transactions is also very low. We are using Unity In-App Purchasing (IAP) 4.13.0. Let us know for any more details and any fix / workaround available. Thanks.
