Apple Watch Missing Developer Mode Option
I have an iPhone 14 running iOS 16.1 and my series 5 watch running watchOS 9.1. I was able to turn on Developer Mode on the phone by going to Settings--> Privacy & Security --> Developer Mode. On the watch however (I'm doing this directly on the watch and not on the watch app on the phone) once I'm in Privacy & Security, there is no option to select Developer Mode. How do I get my watch in Developer Mode in order to get a successful build in xCode?

Importing files to Files.app in iOS 26 Simulator
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.

Does Carplay work in Enterprise apps?
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.

Simulator high CPU usage (CrashReport and MercuryPosterExtension)
Simply opening Simulator app (26.0) causes high CPU usage on macOS Tahoe (26.1). ReportCrash process usage is very high throughout and causes the system to heat up pretty soon. Looking into Console app for the logs found MercuryPosterExtension process is keep on crashing. (Check under Crash Reports) simctl Diagnose https://download.developer.apple.com/OS_X/OS_X_Logs/simctl_Diagnose_Logging_Instructions.pdf Share the Simulator Diagnose report while reporting, Thanks. I have raised a ticket/feedback with Apple. I request all of you to raise one too so this gets fixed soon. Apple Feedback Assistant - FB20985249

Unable to download iOS 26 Beta 5 Simulator
Hello, I'm checking to see if anyone else is experiencing an issue downloading the latest beta simulator. When I try to download the iOS 26 beta 5 simulator in Xcode, the download fails instantly. There is no progress, just an immediate error with no message other than the code itself: DVTDownloadableErrorDomain Code: 41. I've already restarted both Xcode and the Mac multiple times. I have also tried downloading on different networks to rule out a firewall issue.

Developer app on the Mac doesn't play videos in full screen
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.

How are Assets removed?
Hello, I'm trying to figure out the behavior of AssetPackManager.shared.remove(assetPackWithID: ). I'm working with MapKit tiles and currently working on trying projecting them correctly which involves serving the AssetPack locally, downloading, checking alignment, and then deleting and changing. My question is that remove(assetPackWithID: ) completes successfully and the asset pack is removed. This is confirmed by trying to remove the AssetPack again which throws an error. However, the asset is still appearing on MapKit after the removal. This is a bit odd as this persists not only with force killing, but also restarting the device. Please advise on how to properly remove an AssetPack. Thank you iPhone 15 Pro Max (iOS 26.0.1) iPhone 17 Pro Max (iOS 26.0.1)

Forbidden request when using API in Codemagic( Unable to find a team with the given Content Provider ID )
Failed to fetch certificates: This request is forbidden for security reasons - Unable to find a team with the given Content Provider ID '72df6041-c291-4d95-b690-2a3b75ff72f6' to which you belong. Please contact Apple Developer Program Support. https://developer.apple.com/support I have already confirmed that: All API keys were generated correctly. All required roles and permissions have been assigned in App Store Connect. To confirm my doubt, I requested api key from a fellow developer, and that worked in CodeMagic without throwing an error. Could you please help me figure out why the given Content Provider ID is not being recognized? Thank you.

Set date and time in iOS Simulator
I am trying to fix a bug in my iOS app that is dependent upon date and time. Is there any way to set the actual time on the iOS Simulator to a specific date and time? I know that you can set one for the status bar, but that doesn't affect the actual date and time that is reported by the system to apps.

Using alternate app icons with Icon Composer
I've been messing around with converting my app icons to use Icon Composer. My app has multiple app icons, but I've noticed that I cant seem to set .icon files using the alternate app icon api. I believe this is due to the requirement that alternate app icons live in the Assets Catalogue but .icon files go anywhere in your project. Is there any plan to support this? Or am i missing something? I was able to successfully set a .icon file for the primary app icon.

Mergeable Libraries using XCFramework
Hello.

On my app I have the necessity to use mergeable libraries, in my context my libraries are indirect dependency, in other words the dependency isn’t target in my project, and they are XCFramework where they are imported on Framework, Libraries, and Embedded Content session on my app target. Following the documentation on Configuring your project to use mergeable libraries it said. 
  But on Manually configure merging don’t said how to configure to indirect dependencies. 
  So I have tried configure use the linker flag -merge_framework for each XCFramework using -Wl, -merge_framework, {XCFramework_Name}, but I am receiving the following error unknown argument: -merge_framework’ when build the release. 

In app target is set build settings MERGED_BINARY_TYPE = manual; The question is: 
 Is possible using mergeable libraries in XCFramework dependencies ? How I do this? Because on the doc is not clear how to use in indirect dependency like XCFramework. 

 Regards 
Michel Carvalho

Errors with PerfPowerTelemetryClientRegistrationService and PPSClientDonation when running iOS application in Xcode
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. Messages below: Connection error: Error Domain=NSCocoaErrorDomain Code=4099 "The connection to service named com.apple.PerfPowerTelemetryClientRegistrationService was invalidated: Connection init failed at lookup with error 159 - Sandbox restriction."

What exactly an Xcode framework does?
I created 2 iOS projects in Xcode: Project 1: 4 targets (main app + 3 app extensions) 4 static libraries the main app's target dependencies include - 3 app extensions and the 4 libs. the main app's binary is linked to all 4 libs similarly, each extension is linked to all 4 libs Project 2: 5 targets (main app + 3 app extensions + 1 framework) 4 static libraries the main app's target dependencies include - 3 app extensions and the framework each extension is dependent only on the framework the framework's target dependencies include all the 4 static libs As per my understanding, the app bundle size for Project 2 should be less than that of Project 1, since we eliminate duplicating the static libs for each target by using a framework instead. However, I have found that the bundle size is more for Project 2 as compared to the bundle size of project 1. I do not understand, why?

How to test SignificantChange Permission Ask
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?

Discrepancies in MetricKit and Xcode Organizer Data
We recently integrated MetricKit into our app; however, the 90th percentile data does not seem to match the data in Xcode Organizer. The values reported by MetricKit appear to be higher. Additionally, it looks like data for previous app versions is not being updated in Organizer as adoption of the latest version increases. Has anyone else experienced this issue? Could there be a delay in data updates for older versions in Organizer? Are there any known limitations or best practices for ensuring consistency between MetricKit and Xcode Organizer data? Any guidance would be greatly appreciated.
