Hello! I am trying to automate iOS builds for my Unreal Engine game using Unreal Automation Tool, but I cannot produce a functionnal build with it, while packaging from XCode works perfectly. I have tracked down the issue to a missing file. I'm using the Firebase SDK that requires a GoogleService-Info.plist file. I have copied this file at the root of my project, as the Firebase documentation suggests. I have not taken any manual action to specify that this file needs to be included in the packaged app. The Firebase code checks the existence of this file using NSString* Path = [[NSBundle mainBundle] pathForResource: @“GoogleService-Info” ofType: @“plist”]; return Path != nil; If I package my app from XCode using Product -> Archive, this test returns true and the SDK is properly initialized. If I package my app using Unreal Engine's RunUAT.sh BuildCookRun, this test returns false and the SDK fails to initialize (and actually crashes upon trying). I have tried several Unreal Engine tricks to include my file, like setting it as a RuntimeDependecies in my projects Build.cs file. Which enables Unreal Engine code to find it, but not this direct call to NSBundle. I would like to know either how to tell Unreal Engine to include files at the root of the app bundle, or what XCode does to automatically include this file and is there a way to script it? I can provide both versions .xcarchive if needed. Thanks!

Hi everyone, I’m hoping someone here can shed some light on what’s going on with Apple’s one-hour security delay when trying to register an iPhone for development use. I’m currently setting up an app build using Expo / EAS and a paid Apple Developer account. Every time I scan the device registration QR code or try to authorise my iPhone as a development device, I get hit with a “security delay — try again in one hour” message. This happens every single time, even if I wait the full hour. The device is the same iPhone I always use, signed in to the same Apple ID, and verified with 2FA. The only thing unusual about my setup is that I’m using Starlink for internet access. Because Starlink uses dynamic IP routing and your exit node changes frequently (depending on which satellite or ground station you’re on), it looks like I’m signing in from a new location each time — sometimes even hundreds of miles apart. It seems that Apple’s security system flags each of these as a “new login” or “new device registration,” then enforces a one-hour safety lockout. That makes it basically impossible to register my device and proceed with iOS builds or testing. Has anyone else run into this problem while using Starlink (or other dynamic-routing connections like VPNs or cellular hotspots)? And if so — is there any known workaround or setting to whitelist a device, stabilise verification, or bypass the repeated one-hour wait? This feels like an over-protective security feature that doesn’t play well with modern satellite internet setups. Any insights from the Apple engineers or other developers would be hugely appreciated. Thanks, Tim Lazenby

Hello, I am experiencing an authentication issue when submitting my Expo iOS app to App Store Connect using the Expo EAS CLI from the terminal. The exact flow is as follows: I run the submit command in the terminal. I am prompted to enter my Apple ID. After entering the Apple ID, I am prompted to enter my Apple ID password. After the password is accepted, I am prompted to enter a 6-digit verification code. I receive the 6-digit code immediately via SMS or phone call. I enter the code correctly and immediately, but the CLI always returns “Invalid code.” This happens every time. Important notes: The Apple ID and password are correct. The 6-digit code is entered immediately and exactly as received. Logging in to App Store Connect via a web browser with the same Apple ID, password, and SMS code works without any issue. The problem only occurs when authenticating through the terminal using Expo EAS CLI. Could you please advise why the verification code is being rejected in the CLI and how I can successfully authenticate and submit my app?

Hello, I've encountered unexpected behavior related to version information in our app logs, and I'd like to ask for some advice. We reviewed logs collected from a user running our app (currently available on the App Store). The logs are designed to include both the build number and the app version. Based on the build number in the logs, we believe the installed app version on the user's device is 1.0.3. However, the app version recorded in the logs is 1.1.5, which is the latest version currently available on the App Store. In our project, we set the app version using the MARKETING_VERSION environment variable. This value is configured via XcodeGen, and we define it in a YAML file. Under normal circumstances, the value defined in the YAML file (MARKETING_VERSION = 1.0.3) should be embedded in the app and reflected in the logs. But in this case, the version from the current App Store release (1.1.5) appears instead, which was unexpected. We'd like to know what might cause this behavior, and if there are any known factors that could lead to this. Also, is it possible that MARKETING_VERSION might somehow dynamically reflect the version currently available on the App Store? YAML: info.plist:

I am developing an Augmented Reality (AR) navigation application for the iPad, utilizing the ARCL library to place Points of Interest (POIs) in the real world. The application's behavior varies significantly based on the device's networking configuration: Cellular Network (Expected Behavior): On an iPad with a cellular modem, when using the cellular network, all POIs are placed accurately with correct orientation. Wi-Fi Only (Expected Behavior): On a Wi-Fi-only model (no GPS chip), POI placement is inaccurate, confirming the need for an external GPS receiver for that hardware configuration. Cellular + Wi-Fi (Anomalous Behavior): The iPad is a cellular model (equipped with GNSS/GPS). The device is connected to a Wi-Fi network (enforced via an MDM profile, preventing the user from disabling Wi-Fi). When actively connected to this specific Wi-Fi network, the AR POIs consistently display with an incorrect orientation and placement, even though the device hardware has a dedicated GPS chip. The placement error strongly suggests that the device's determined location or heading is erroneous. It appears that the active Wi-Fi connection is somehow interfering with or overriding the high-accuracy GNSS/GPS data, leading to a flawed Core Location determination that negatively impacts the ARCL world tracking and anchor placement. Has anyone experienced a scenario where an active Wi-Fi connection on a cellular iPad model causes Core Location to prioritize less accurate location data (potentially Wi-Fi-based location services) over the device's built-in GNSS/GPS, resulting in severe orientation errors? We observed that on Apple map(native application) as well it is showing wrong location and orientation when it is connected to WiFi

I am located in Taiwan and recently updated my Mac to the latest OS and installed the newest Xcode. However, I’m experiencing extremely slow download speeds when trying to add the iOS 26.2 Simulator Runtime (approx. 8GB) via Xcode > Settings > Platforms. It is currently downloading at a rate of only 500MB per hour, which is impractical. I have checked the official downloads page but couldn't find a standalone DMG link for this specific version. My questions are: Is there a direct download link (DMG) available on the Apple Developer portal for the iOS 26.2 Simulator? If no direct link exists, are there any recommended methods to accelerate the download? (e.g., using terminal commands or changing DNS settings). Any help or direct URLs would be greatly appreciated. Thank you!

I have a Apple Developer accounts for development purposes only and that is also used for testing builds via TestFlight. Is the Age Ratings Responses updates due by the end of January 2026 still required even to send builds to TestFlight?

Hi all, I'm trying to integrate Apple’s DeviceCheck API into my Flutter iOS app. I already have everything set up on the backend — the Apple private key, key ID, team ID, and DeviceCheck capability. The backend is generating and signing the JWT correctly and making requests to Apple. However, I’m currently stuck on the frontend (Flutter): 👉 How can I generate the device_token required by the DeviceCheck API (via DCDevice.generateToken) in a Flutter iOS app? I understand that DCDevice.generateToken() must be called from native Swift code. I previously attempted to use a MethodChannel to bridge this in Swift, but would prefer not to write or maintain native Swift code if possible. I've looked for a prebuilt Flutter package to handle this, but nothing exists or is up-to-date on pub.dev. Main Question: Is there any Apple-supported way to generate the device_token for DeviceCheck from a Flutter app without writing Swift code manually? If not, is DCDevice.generateToken() the only possible approach, and must I implement this via Swift and Flutter platform channels? Thanks!

Hi, I’m currently developing a watchOS app and ran into an issue where I can’t enable Developer Mode on my Apple Watch. Device info: Apple Watch Series 9 (watchOS 10.4) Paired with iPhone 14 Pro (iOS 17.4.1) Xcode 15.3 (macOS 15.5, Apple Silicon) Issue: When I try to run the app on my physical watch device, Xcode prompts that Developer Mode needs to be enabled. However, there is no approval request on the Apple Watch, and no Developer Mode option appears under Settings → Privacy & Security. I’ve already tried the following: Rebooting both devices Unpairing and re-pairing the watch Erasing and setting up the watch again Signing out and back into my Apple ID Using the latest Xcode version (15.3 and 16.3 both tested) Running clean builds and checking provisioning profiles Attempting install via both simulator and physical device Still no luck — the app will not launch on the Apple Watch due to Developer Mode being disabled, and the option is missing entirely from Settings. I visited an Apple Store Genius Bar, but they couldn’t help and told me to contact Developer Support. I’ve already submitted a support request, but in the meantime I wanted to ask here in case anyone else has experienced this and found a workaround. Thanks in advance.

How can I allow the popup I am encountering while I run my UI tests with video recording in the Github actions. Since these tests are running on VMs, it's not possible to manually click Allow. Also the remote robot cannot interact with OS-level dialogs.

Hey guys! I downloaded Apple’s Icon Composer to build my iOS 26 app icon. I exported my SVG from Illustrator (and verified it through Canva and the W3C validator). However, when I import it into Icon Composer, it looks really weird . There are these bubble-like artifacts appearing in the center. Here's my orignal svg icon file trace-logo.txt Any help will be appreciated! Best, Justin

I regularly bump into folks confused by this issue, so I thought I’d collect my thoughts on the topic into a single (hopefully) coherent post. If you have questions or comments, put them in a new thread here on the forums. Feel free to use whatever subtopic and tags that apply to your situation, but make sure to add the Debugging tag so that I see your thread go by. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = "eskimo" + "1" + "@" + "apple.com" Testing and Debugging Code Running in the Background I regularly see questions like this: My background code works just fine in Xcode but fails when I download the app from the App Store. or this: … or fails when I run my app from the Home screen. or this: How do I step through my background code? These suggest a fundamental misunderstanding of how the debugger interacts with iOS’s background execution model. The goal of this post is to explain that misunderstanding so that you can effectively test and debug background code. Note The focus of this post is iOS. The advice here generally applies to any of iOS’s ‘child’ platforms, so iPadOS, tvOS, and so on. However, there will be some platform specific differences, especially on watchOS. This advice here doesn’t apply to macOS. It’s background execution model is completely different than the one used by iOS. Understand the Fundamentals The key point to note here is that the debugger prevents your app from suspending. This has important consequences for iOS’s background execution model. Normally: iOS suspends your app when it’s in the background. Once your app is suspended, it becomes eligible for termination. The most common reason for this is that the system wants to recover memory, but it can happen for various other reasons. For example, the system might terminate a suspended app in order to update it. Under various circumstances your app can continue running after moving to the background. A great example of this is the continued processed task feature, introduced in iOS 26 beta. Alternatively, your app can be resumed or relaunched in the background to perform some task. For example, the region monitor feature of Core Location can resume or relaunch your app in the background when the user enters or leaves a region. If no app needs to be executing, the system can sleep the CPU. None of this happens in the normal way if the debugger is attached to your app, and it’s vital that you take that into account when debugging code that runs in the background. An Example of the Problem For an example of how this can cause problems, imagine an app that uses an URLSession background session. A background session will resume or relaunch your app in the background when specific events happen. This involves two separate code paths: If your app is suspended, the session resumes it in the background. If your app is terminated, it relaunches it in the background. Neither code path behaves normally if the debugger is attached. In the first case, the app never suspends, so the resume case isn’t properly exercised. Rather, your background session acts like it would if your app were in the foreground. Normally this doesn’t cause too many problems, so this isn’t a huge concern. On the other hand, the second case is much more problematic. The debugger prevents your app from suspending, and hence from terminating, and thus you can’t exercise this code path at all. Seek Framework-Specific Advice The above is just an example, and there are likely other things to keep in mind when debugging background code for a specific framework. Consult the documentation for the framework you’re working with to see if it has specific advice. Note For URLSession background sessions, check out Testing Background Session Code. The rest of this post focuses on the general case, offering advice that applies to all frameworks that support background execution. Run Your App Outside of Xcode When debugging background execution, launch your app from the Home screen. For day-to-day development: Run the app from Xcode in the normal way (Product > Run). Stop it. Run it again from the Home screen. Alternatively, install a build from TestFlight. This accurately replicates the App Store install experience. Write Code with Debugging in Mind It’s obvious that, if you run the app without attaching the debugger, you won’t be able to use the debugger to debug it. Rather: Extract the core logic of your code into libraries, and then write extensive unit tests for those libraries. You’ll be able to debug these unit tests with the debugger. Add log points to help debug your integration with the system. Treat your logging as a feature of your product. Carefully consider where to add log points and at what level to log. Check this logging code into your source code repository and ship it — or at least the bulk of it — as part of your final product. This logging will be super helpful when it comes to debugging problems that only show up in the field. My general advice is that you use the system log for these log points. See Your Friend the System Log for lots of advice on that front. One of the great features of the system log is that disabled log points are very cheap. In most cases it’s fine to leave these in your final product. Attach and Detach In some cases it really is helpful to debug with the debugger. One option here is to attach to your running app, debug a specific thing, and then detach from it. Specifically: To attach to a running app, choose Debug > Attach to Process > YourAppName in Xcode. To detach, choose Debug > Detach. Understand Force Quit iOS allows users to remove an app from the multitasking UI. This is commonly known as force quit, but that’s not a particularly accurate term: The multitasking UI doesn’t show apps that are running, it shows apps that have been run by the user. The UI shows recently run apps regardless of whether they’re in the foreground, running in the background, suspended, or terminated. So, removing an app from the UI may not actually quit anything. Removing an app sets a flag that prevents the app from being launched in the background. That flag gets cleared when the user next launches the app manually. Note In some circumstances iOS will not honour this flag. The exact cases where this happens are not documented and have changed over time. Keep these behaviours in mind as you debug your background execution code. For example, imagine you’re trying to test the URLSession background relaunch code path discussed above. If you force quit your app, you’ll never hit this code path because iOS won’t relaunch your app in the background. Rather, add a debug-only button that causes your app to call exit. IMPORTANT This suggestion is for debugging only. Don’t include a Quit button in your final app! This is specifically proscribed by QA1561. Alternatively, if you’re attached to your app with Xcode, simply choose Product > Stop. This is like calling exit; it has no impact on your app’s ability to run in the background. Test With Various Background App Refresh Settings iOS puts users in control of background execution via the options in Settings > General > Background App Refresh. Test how your app performs with the following settings: Background app refresh turned off overall Background app refresh turned on in general but turned off for your app Background app refresh turned on in general and turned on for your app IMPORTANT While these settings are labelled Background App Refresh, they affect subsystems other than background app refresh. Test all of these cases regardless of what specific background execution feature you’re using. Test Realistic User Scenarios In many cases you won’t be able to fully test background execution code at your desk. Rather, install a TestFlight build of your app and then use the device as a normal user would. For example: To test Core Location background execution properly, actual leave your office and move around as a user might. To test background app refresh, use your app regularly during the day and then put your device on charge at night. Testing like this requires two things: Patience Good logging The system log may be sufficient here, but you might need to investigate other logging solutions that are more appropriate for your product. These testing challenges are why it’s critical that you have unit tests to exercise your core logic. It takes a lot of time to run integration tests like this, so you want to focus on integration issues. Before starting your integration tests, make sure that your unit tests have flushed out any bugs in your core logic.

Hey, I am using the terminal a lot. Since I updated to Sonoma (so, really a long time ago). My prompt or more precise the hostname always changes between three states. Sometimes it is username@Macbook-Pro-of-XXX, sometimes username@MacbookPro and sometimes it's username@xxxxxxxx-yyyy-zzzz-aaaa-bbbbbbbbbbbb. The latter is probably my UUID. Does anyone have a clue why this randomly changes?

In our Unity App for iOS build, when we opened the PDF from the app, it is automatically opening in landspace mode instead of portrait. In the android and windows apps, we are able to open in the portrait mode. We tried to make the changes in the project settings but it did not change. Any way in which we can acheive this would be helpful for us.

The app I'm working on has iOS 16.0 as target. Recently Live Activities support was added, but then it started crashing when running on iOS 16.0 devices. After some investigation, I've found that the culprit was the presence of NSUserActivityTypeLiveActivity and WidgetCenter.UserInfoKey.activityID, even though they were inside an @available(iOS 17.2, *) block. If I comment these two variables, the app work as expected. I've also tried adding #if canImport(ActivityKit) around the code, but without success. But if the @available isn't working, how can I prevent this? It looks like a bug, since the documentation says that NSUserActivityTypeLiveActivity is supported but iOS 14.0+, but I'm pretty sure it was introduced on 16.1. This is the only output I get with the crash: dyld[66888]: Symbol not found: _$s9WidgetKit0A6CenterC11UserInfoKeyV10activityIDSSvgZ Referenced from: <D6EFF120-2681-34C1-B261-8F3F7B388238> /Users/<redacted>/Library/Developer/CoreSimulator/Devices/8B5B4DC9-3D54-4C91-8C88-E705E851CA0F/data/Containers/Bundle/Application/DB6671FF-CB07-4570-BD63-C851D94FAF29/<redacted>.app/<redacted>.debug.dylib Expected in: <C5E72BB5-533F-3658-A987-E849888F4DFC> /Library/Developer/CoreSimulator/Volumes/iOS_20A360/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 16.0.simruntime/Contents/Resources/RuntimeRoot/System/Library/Frameworks/WidgetKit.framework/WidgetKit
