Hardware Specifications Regarding the LiDAR scanner in the iPhone 13/14/15/16/17 Pro series, could you please provide the following technical details for academic verification: Point Cloud Density / Resolution: The effective resolution of the depth map. Sampling Frequency: The sensor's refresh rate. Accuracy Metrics: Official tolerance levels regarding depth accuracy relative to distance (specifically within 0.5m – 2m range). Data Acquisition Methodology For a scientific thesis requiring high data integrity: Does Apple recommend a custom ARKit implementation over third-party applications (e.g., Polycam) to access raw depth data? I need to confirm if third-party apps typically apply smoothing or post-processing that would obscure the sensor's native performance, which must be avoided for my error analysis.

I am developing CarPlay addition on our app. Which is distributed with the Enterprise In distribution method, so we do not have a product in the App Store. I am wondering if CarPlay support can be provided in applications distributed with the Enterprise in distribution method? If this is not possible, I will inform management that this is not possible. I am waiting for your answers, thanks.

Background Assets can support a maximum of 200G. Will the Apple server perform file comparison? For example, file0 is included in both a.aar file and b.aar file. On the Apple server, does it occupy twice the size of a single file?

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.

Hello, According to documentation, the App Store does not re-download the entire app when updating, but instead generates an update package containing only the changed content compared to the previous version. I’d like to clarify the following points: 1. Granularity of file changes If only part of a large file changes, does the update package include the entire file, or does it patch only the modified portions within that file? 2. Guideline on separating files The documentation recommends separating files that are likely to change from those that are not. How should this be interpreted in practice? 3. Verifying the diff result Is there a way for developers to check the actual diff result of the update package generated by the App Store without submitting the app? Is there a diff command tool or comparison method closer to the actual App Store update process? 4. Estimating update size during development For apps with large-scale resources, minimizing update size is critical. Are there any tools or best practices to estimate the size of the update package before submitting to the App Store? Any clarification or reference materials would be greatly appreciated. Thank you.

How to replicate: Design a icon in icon composer Save it and put the .icon file in your project, then in your targets put the name of the .icon file in there. Either clean build folder or restart IDE One Error: unable to open dependencies file (/Users/user/Library/Developer/Xcode/DerivedData/project-fqrfzzkwgrutdabmcqjeupvyetci/Build/Intermediates.noindex/project.build/Debug/project.build/assetcatalog_dependencies_thinned) And one warning: Icon export exited with status 255, signal 0 Is this a known issue or a easy fix? Or is it a issue on my end? Thanks

I used to develop iPhone apps about a decade ago and am now back at it with an iPhone and companion Apple Watch app. Why does it suck so bad? I a must be doing something wrong, but what I am doing is out of the box. The majority of the time when I go to build on the watch I get: Previous preparation error: A connection to this device could not be established.; Timed out while attempting to establish tunnel using negotiated network parameters. Which I then first try to force quit the app on the watch and if that does not work, reboot the watch (which is pretty ridiculous). I tried Gemini and it gave me the following explanation: This is arguably the single most frustrating error in the entire watchOS development ecosystem. As an expert, I can tell you that you are not doing anything wrong; you are fighting a fragile architecture. Here is the technical breakdown of why this happens and a workflow to mitigate it without constant reboots. The Technical "Why" This error message reveals that the issue lies in the CoreDevice (and formerly usbmuxd) infrastructure, specifically in the secure transport layer. The "Tunnel" Failure: Xcode attempts to establish a secure, encrypted tunnel (DTXConnection) to the Apple Watch to push the debugger and the app binary. Unlike the iPhone, which can sustain a high-bandwidth connection easily, the Watch aggressively manages its radios (Bluetooth vs. WiFi vs. AWDL) to save battery. The "Handshake" Timeout: If the Watch is on Bluetooth (Low Energy) when Xcode initiates the tunnel, the bandwidth is insufficient. The system tries to escalate the connection to WiFi (or Apple Wireless Direct Link). If this negotiation takes even a few milliseconds too long—due to 2.4GHz interference, router mDNS configuration, or the Watch CPU being throttled—the handshake times out. The "Previous Preparation Error": This is the insidious part. Once the handshake fails once, Xcode’s device service caches that failure state for the device UUID. It marks the device as "unreachable" to prevent the IDE from hanging indefinitely on subsequent tries. Why you see it constantly: You aren't actually triggering a new connection attempt; you are hitting the cached "failed" state immediately. Unfortunately, the solutions it gives me are: The "Wired Proxy" Method (Most Reliable) This is the gold standard for watchOS debugging. Do not rely on "Connect via Network" for the Watch directly if you can avoid it. Disable WiFi on your Mac (temporarily) or ensure the Mac and iPhone are on the exact same SSID. Plug your iPhone into the Mac via USB. Ensure the Watch is paired to that iPhone. Result: Xcode will tunnel the instructions through the USB connection to the Phone, and the Phone acts as a high-bandwidth proxy to the Watch. This eliminates the "Mac-to-Watch" WiFi negotiation failure point. Do you hit this regularly? What do you do to make for a smooth development and deployment process? Or is it really this fragile? Thanks for any help! Bryan

Hi, I am developing IOS(Android App) with React Native. I am very confused about cocoapods and pod and how to correctly install it on my new Macbook Pro M4. I am not using bash but I am using zsh. Note, actuallywhich pod return nothing During the preparation of my environment, it say CocoaPods is one of the dependency management system available for iOS. CocoaPods is a Ruby gem. You can install CocoaPods using the version of Ruby that ships with the latest version of macOS. the web site show two commands gem install cocoapods sudo gem install cocoapods I saw another command as well brew install cocoapods During different processes, I experienced several time the following error (Command 'pod install failed) Command pod install failed. └─ Cause: pod install --repo-update --ansi exited with non-zero code: 1 Then I am confused about cocoapods and pod. Are both he same? With my previous MacBook pro, I spend time to install cocoapod on my profile because Ruby was not the latest version on the system. But apparently, on my new Macbook Pro M4, the command ruby -v return (as well) ruby 2.6.10p210 (2022-04-12 revision 67958) [universal.arm64e-darwin25] The current stable version is 4.0.0. I bought a new macbook pro M4 and I reinstalled node and all package for Rect Native 0.81 a expo 54 excepted cocoapods. Now, I need to configure the push notification and it's time to install cocoapods as it's require here But on my new macbook pro, I would like to make sure I do it correctly and I kindly ask your help and recommandation to install Ruby and cocoapods/pod Q1: Should I install cocoapods with brew install cocoapods or gem install cocoapods? Q2: what's is the difference or the common point with cocoapods and pod? Cocoapod web site said If using the default Ruby included with macOS, installation will require you to use sudo when installing gems As ruby -v print 'ruby 2.6.10p210', I suppose, I should not install cocoapod with sudo You can use a Ruby Version manager such as RVM or rbenv to manage multiple Ruby versions, or you can use Homebrew to install a newer Ruby with brew install ruby. As far I understand, I should not install cocoapods with the Ruby version of the system, then I suppose the command Q3: Will 'brew install cocopads' install the latest version on my profile? Will it upgrade the system version Q4: What will do the command brew install rbenv ruby-build rbenv install 3.2.2 (or better: rbenv install 4.0.0) in comparison with brew install ruby My guess I suppose that the following will help, but it would nice if you could correct me and clarify # All should be done in my profile brew install rbenv ruby-build echo 'eval "$(rbenv init - bash)"' >> ~/.zprofile source ~/.zprofile rbenv install 4.0.0 # rbenv global 4.0.0 # What is it? ruby -v gem install cocoapods Q5: But then, what about pod and the error message Command pod install failed. As you can see, I am a bit confused and I would appreciate your clarification I thanks you for your help and clarification and I wish you a happy new years

I've suddenly started seeing hundreds of the same block of four error messages (see attached image) when running my app on my iOS device through Xcode. I've tried Cleaning the Build folder, but I keep seeing these messages in the console but can't find anything about them. Phone is running iOS 26.1. Xcode is at 16.4. Mac is on Sequoia 15.5. The app is primarily a MapKit SwiftUI based application.

I am encountering an issue where the application running on a physical device does not reflect the most recent source changes. Observed behavior On the device, the application behaves as if an older binary is running. Specifically: Newly added debug UI labels do not appear. The logs still show old debug prints instead of new ones. Steps taken to ensure a clean install: Changed the bundle identifier Set a new display name (the app still showed the old display name when I click run). Deleted the app manually from the device before every reinstall. Build and install steps Performed multiple clean builds with a fresh Derived Data path. Built from terminal using xcodebuild (Debug configuration, physical device target, automatic provisioning). Installed using: xcrun devicectl device install app Verified: The updated source files are listed under Compile Sources and compiled from the expected path. The bundled Info.plist includes the new bundle identifier and display name. Installation output confirms new bundle identifier. Question What could cause a newly built and installed application to run with behavior from an older binary? Are there recommended ways to verify that the device is actually launching the latest installed build, and to ensure stale binaries are not being executed? Any guidance on additional diagnostics or misconfigurations to check would be appreciated.

I am trying to add promotional offers in my iOS App. The signature is being verified through a google cloud function. My user id, signature, and product and offerIds return perfect. Promotional offer appears in the payment sheet as well. When applying for payment, the "ding" sound comes as well. But then I get the UIAlert with Unable to Purchase Contact developer. Error code in logs is 3903

I need to install the AirPlay profile on an iphone to watch decrypted traffic in ATS for development work on CarPlay. The documentation for ATS says to click "Utilities -> Download Profiles -> AirPlay Diagnostic Mode". When I do this, it brings up a file dialog, presumably to select a location to download. But nothing happens. The other profiles launch a web browser and download the .mobileconfig profile. How do I get the AirPlay profile? Am I misunderstanding how this is supposed to work? I found ATSAssetsInfoDefault.plist which references these files. And they all have https://developer.apple.com/services-account/download?path=/iOS/iOS_Logs/... except the AirPlay profile, which is type "slug" and just says ats-airplay-diagnostic-mode-profile. Is this a bug in the app?

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, Problem When playing videos on the Developer app on the Mac, there is no full screen button for the video. So it is not possible to play the video in full screen. Note I am not referring to the app going into full screen, the issue is with there is no option to play the video in full screen. Environment OS: macOS 26.2 (25C56) Developer app: Version 10.8.3 (1083.3.1) Feedback FB21343934 Recording Question Are others also facing this issue? Is there a workaround? Suggestion This seems to be recurring problem that seems get broken with app / OS releases. Please write some UI tests to ensure the full screen button is present. Would really appreciate if this gets fixed.

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

I'm developing for compliance with Texas law in the United States. Currently, I'm encountering an issue where I want to test the feature point "when the app undergoes significant changes, a supervised user initiates a request." However, during actual testing, the app pops up an error message: "Can't Ask, An Unknown error occurred." Additionally, I see the following error message in the Xcode Console: "Error Domain=AskToCore.ATMessageComposeValidationError Code=4 'The user is in a region that does not support this type of ask.' UserInfo={NSLocalizedFailureReason=The user must be in a supported region to use this feature., NSLocalizedRecoverySuggestion=Please ensure the user is in an eligible region., NSLocalizedDescription=The user is in a region that does not support this type of ask.}" I am indeed not in the Texas region. I want to conduct full-process testing before the feature is released to the App Store. What should I do? Apart from Sandbox testing (which, in fact, doesn't show any pop-ups either), how can I test under real-world conditions?

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 developing a simple watch app and I use my personal watch for development with Xcode. Personal watch is series 10 gps only. I have two other watches that I want to use for testing the app, but not needing them to be connected to Xcode. The test watches have cellular option, and I need a cell plan per watch because the watches need to be standalone, not counting initial setup. To get the standalone cell plan the watches need to be configured using AWFK. Here is what I have tried/current issues. I switch between all three watches on my phone using the watch app. Originally tried to put test watches in developer mode, thinking I would connect to Xcode, developer mode is not available when watch is setup using AWFK. Pushed the watch app to apple connect, setup TestFlight group, added the test users and my phone user, accepted invites TestFlight is installed on my phone, I see the testflight setup for the watch app I set a test watch using watch app on the phone, run install for the test app from TestFlight on the phone, spinner moves for awhile then goes back to Install. I am not able to get the watch app installed on the test watches from the phone. Is what I am attempting to do supported? I haven't found much specific documentation on this. If I pair the test watches as regular watches, set them to developer mode, can I pair them again as AWFK and will developer mode survive the switch? Or is there something really simple that I'm overlooking? Appreciate any help that can be extended.

My application always crashes at the same position when I open it on my iPad Air. It doesn't crash in debug mode which makes it very difficult for me to find the issue.

In previous versions of the simulator, it was possible to import files into the Files app by dragging them from the Finder into the Simulator. It appears that in the iOS 26 Simulator, this opens the file in Safari. I've only tried it with .json files so far. The documentation at https://developer.apple.com/documentation/xcode/sharing-data-with-simulator says that the original behaviour should happen: To add files to Simulator, select one or more files in Finder on your Mac, then click the Share button. Select Simulator from the share destination list. Choose the simulated device from the drop-down list. Simulator opens the Files app, and lets you select where to save the files. I'd love to learn if this is intentional behaviour, and if so, what workarounds there might be. I use this pattern quite a lot, as I have a HealthKit app, and I've built a system that allows me to export workouts as JSON files from a real device, that I can then import into a simulator for testing. Edit: I found a workaround. Make a folder in Files.app, then search for it within ~/Library/Developer/CoreSimulator/Devices. Open the folder in Finder, then add any files you want to be available in the Simulator.
