Use of non-public or deprecated APIs
Hello, "This issue is blocking App store approval" I have tried pushing my application to Appstore. However it has been rejected on the following ground: _"As we discussed, the app uses or references the following non-public or deprecated APIs: Frameworks/CommonLibrary.framework/CommonLibrary Symbols: • _SecCertificateIsValid The use of non-public or deprecated APIs is not permitted, as they can lead to a poor user experience should these APIs change and are otherwise not supported on Apple platforms."_ I have scanned the app using "strings" tool & "otool -ov" tool. But they have come out clean. No Non-public or deprecated APIs detected. Please advise which tool can be used to scan the CL to locate where the deprecated API or non-public API lies and also how to rectify the same. Thanks Saikat Bakshi.

Unexpected performance penalty attributed to first Swift Testing test
I have a Swift package with a test suite that contains some tests implemented with Swift Testing. Locally, they run quickly, but when I run them on Semaphore CI (https://semaphore.io), the first Swift Testing test to execute incurs a performance penalty. I'm running the tests with xcodebuild on iOS Simulator: xcodebuild test \ -scheme "Scheme" \ -workspace Workspace.xcworkspace \ -destination "platform=iOS Simulator,name=iPhone 16,OS=18.2" The scheme is configured to use a test plan that has parallelization disabled. Here's an excerpt from the output showing what I'm seeing: Test Suite 'All tests' started at 2025-04-03 07:47:37.328. ◇ Test run started. ↳ Testing Library Version: 102 (arm64-apple-ios13.0-simulator) ◇ Iteration 1 started. ◇ Suite <redacted> started. ◇ Test foo() started. ✔ Test foo() passed after 23.063 seconds. When foo() is not the first test it runs in under 100 ms. The reason that I have parallelization disabled is that I was initially seeing all of the tests in this suite incur a performance hit. But now it's clear that there must be some startup cost. Things I'm wondering: What is this startup penalty? Why don't I encounter it locally? Why is it attributed to the first test? (this seems like a bug) My wild guesses around 1 so far have been… maybe some simulator clone is booting. I've tried to rule that out by disabling parallelization, but maybe there's still something there. maybe swift testing is getting loaded lazily and there's some kind of dynamic linking cost Thoughts on 2… maybe there's some one-time penalty when using swift testing that I've already incurred locally but that has not yet been incurred in the CI image Guidance welcome! x-posted: FB17102970 (Unexpected performance penalty attributed to first Swift Testing test) https://forums.swift.org/t/first-swifttesting-test-always-slow/79066

Missing Apple-Hosted Background Assets info
After combing the forums and release nodes, here are some extra notes to help other developers using Apple-Hosted Background Assets. I don't promise I got this perfect, but it may help direct you. AssetPack.Status is an OptionSet (not an enum!) - Critical API detail missing from guide It's a bitmask where values can be combined 2⁰ (1) = available to download 2¹ (2) = update available 2² (4) = up to date 2⁶ (64) = downloaded Example: status value 69 = 0b1000101 = available + up to date + downloaded Use .contains() method to check specific flags AssetPack.version property - Undocumented feature Auto-assigned by App Store Connect for Apple-hosted packs Increments with each upload of same asset pack ID No file deduplication across asset packs Same file in two packs = counts twice toward 200GB limit Best practice: create separate pack for shared files Shared namespace path requirements Asset pack ID is NOT part of file path Each file must have unique relative path across ALL app's asset packs Example: Foo/10/239/414.png and Bar/10/239/414.png are distinct and won't collide Additional url(for:) bugs beyond iOS 26.1 fix iOS 26 Beta 5: "item with same name already exists" error Workaround: Request URL for directory, then manually append filename TestFlight-only availability - Major limitation not mentioned! Apple-hosted packs currently ONLY work for internal testers on TestFlight or from App Store. Won't work from Xcode until "later this year" HTTP 400 errors expected for non-TestFlight installs ba-serve port workaround URL override port bug exists on multiple device types Use ba-serve -p 443 instead of custom ports

iOS AppPresser app logs out automatically after any period of time (Android works fine)
Hello, Thank you for taking the time to read this and hopefully helping me. https://apps.apple.com/gb/app/gdl-graded-darts-leagues/id1592502150 I created a mobile app using AppPresser that is connected to my WordPress website. The iOS app is logging users out when they close the app and go back to it. The login session does not persist, and users are forced to log in again frequently. This happens at any time period between closing and opening the app. This only happens on iOS — Android keeps the session active as expected. I don't know if I've included this post in the correct topic, sorry. Thanks again for any ideas and assistance!

Error build expo EAS
I'm trying to create a new build from VSC through EAS (expo) but it's failing and returning the error I'm attaching. I'm running the command eas build --profile preview --platform ios. I have an "App Manager" account, my colleague has the same role and he can do builds normally. I have other permissions and accesses ok, as can be seen in the attached picture, but apparently I have the issue in "register bundle identifier". Does anyone faced the same issue? How can I solve this? What step I'm missing? Thanks in advance!

Unable to open mach-O at path
Hi, there's this point at which a beginner needs to beg for help. Unable to open mach-O at path: /Library/Caches/com.apple.xbs/Binaries/RenderBox/install/Root/System/Library/PrivateFrameworks/RenderBox.framework/default.metallib Error:2 I get this everytime I select a month and year on a custom date picker, I believe because I try to force the ".generateChartData()" for the chart to update. I guess the problem might be that the ".onAppear" and ".onChange" are conflicting with each other? } .onChange(of: showDatePicker) { viewModel.startDate = selectedDate viewModel.generateChartData() } } .onAppear { viewModel.generateChartData() }

symbolicate crashlog using .symbols files instead of dSYMs
Hi, Some crashes downloaded from TestFlight aren't symbolicated by Xcode and I don't know why, here's an example: Although all uploaded builds contain debug symbols (Symbols directory with .symbols files) and other crashlogs in the same version are symbolicated just fine (also visible on the above SS). I have access only to the .symbols files but not to the original dSYMs and I wonder how to perform symbolication manually. I tried pointing atos and symbolicatecrash utilities to respective .symbols file, but they are unable to work with it. I'm sure it's possible as TestFlight symbolicates crashlogs using only .symbols files somehow. Could you give a hint?

App crashes on start in TestFlight
Hi, I have a .NET MAUI app running on .NET 9. When I test locally in debug or release mode it works perfectly fine, but when testing from TestFlight it crashes almost immediately every time. I have sent the crash report to TestFlight and produced the symbolicated.crash file (attached), but I'm not sure it's helpful for understanding how to fix the issue. If anyone can help me understand what the issue might be and any possible fixes it'd be very much appreciated. I'm developing using Visual Studio 2022 paired to my Mac. I have distributed previously without issue, but now can't seem to, even after reverting recent code. net9.0-ios 15.0 symbolicated.crash

On Demand Resources as Legacy Technology
I read on this documentation : https://developer.apple.com/help/app-store-connect/reference/app-uploads/on-demand-resources-size-limits that On Demand Resources a legacy technology. Does this mean ODR will be deprecated? If so, when will it officially take effect? Our application is planning to use it, so we need more information to support our decision.

Downgrade Developer Test-Device to iOS 18.7.X
Hi, I accidentally upgraded my test device (iPhone 13 mini) to iOS 26. I really need to downgrade it to 18.7.X again. It seems this isn't possible since Apple doesn't sign the .ipsw anymore. Is there really no way for a paying developer to downgrade her test devices? (Please don't tell me to use the support forums, this is a concerning a developer test device)

Running tests on multiple simulators and local mock servers
Hello, I have a question about running tests on multiple simulators. Currently, my company has a WDIO+Appium test suite with XCUITEST driver that runs on a single simulator through a mockttp proxy (we are intercepting and mocking some of the responses from our APIs and pass through the rest). In order to route the traffic we are currently using 'networksetup -setsecurewebproxy '. Everything works as expected. With growing number of tests we'd like to scale number of simulators on a single host to 3-5. We have a working setup but the problem are system-wide proxy settings routing traffic from multiple simulators, which we can't distinguish by UDID or any other means, we know of. We can spin multiple mock servers on the same machine but we are struggling to find the way to route the traffic on a simulator basis. In the end, both options are viable: 1 mock server running for multiple simulators N number of mock servers for N number of simulators Has anyone had the same/similar problem? How to approach this? We are currently running on Sequoia OSX and platform version 18.6. Thanks!

Controlling UIDesignRequiresCompatibility via Remote Config
Hello, I am currently in the process of gradually adding support for LiquidGlass to my app. The transition is taking place incrementally, i.e., new screens and minor features are gradually being adapted to the new design and already deployed. Currently, the old design is still active via the feature flag UIDesignRequiresCompatibility, as the existing UI should remain locked for the public app store version until the transition is complete. My challenge is as follows: I would like to work with the new LiquidGlass design during development without having to manually change the UIDesignRequiresCompatibility flag with each deployment. Ideally, I am looking for a solution where: • the new design is only activated for me (e.g., specific account or specific devices) • the old design remains active for all other users • the App Store version can be delivered unchanged So my question is: Is it possible to control UIDesignRequiresCompatibility via remote config or server-side logic in order to activate the new design specifically for certain users or devices? I have observed similar behavior on WhatsApp—two devices with the same app version, but only one shows the new design. This suggests server-side or remote config-based control. Do you have any experience or recommendations on how to implement something like this cleanly? Kind regards Heinz
