I just updated my device to iOS 18.3 and despite it connecting to my computer, it doesn't appear in Xcode. Some quick troubleshooting led me to the theory that I need to download the matching simulator runtime for it to appear. But I have searched far and wide and the latest sim runtime is ios 18.2 Am I missing something here?

When I try to run a simple executable from Cmake, I get this error. dyld[5005]: dyld cache '(null)' not loaded: syscall to map cache into shared region failed dyld[5005]: Library not loaded: /usr/lib/libSystem.B.dylib Referenced from: <7EB1C677-BB05-338C-8B29-CC2803CB8C21> /Users/pop/Desktop/Lang Reason: tried: '/usr/lib/libSystem.B.dylib' (no such file), '/System/Volumes/Preboot/Cryptexes/OS/usr/lib/libSystem.B.dylib' (no such file), '/usr/lib/libSystem.B.dylib' (no such file, no dyld cache), '/usr/local/lib/libSystem.B.dylib' (no such file) I have tried looking for my file sudo find / -name libSystem.B.dylib but not luck. I am using an M1 chip and Ventura 13.1. Please ask for more details if you need them, as I really have no idea what to do about my problem.

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?

It is gone from where I used to find it on Apple’s web site. Is it deprecated or no longer available?

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.

Description When starting the iOS simulators on macOS-15 intel image, the following assertion happens: The same issue not showing for macOS 15-arm64 image.

I am getting the following warning printed in the console while my app is running Invalid profile 'c2ci': tags 'gTRC' and 'desc' overlap Console metadata specifies it comes from ColorSync at com.apple.colorSync How to fix this? It prints a lot in the console.

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.

Hi, I have just updated my MacBook to Tahoe Beta 2, but now I cannot boot the iOS simulator. Where can I download the next Xcode beta? The Application download page is still showing the Xcode beta 1 build. Cheers, Jeff

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.

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.

Hi I'm building native app for SearchAds. Is it possible to use app specific password with SearchAds API or get a token using app specific password? I know its possible using JWT: https://developer.apple.com/documentation/apple_search_ads/implementing_oauth_for_the_apple_search_ads_api But using that in the app is not very user friendly even if the app will generate public and private keys.

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.

Does anyone know where I can get to the API diffs for iOS 18 -> iOS 26?

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)

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.

When I'm inspecting a WKWebView in a simulator and the WKWebView loads a local URL with a port number, I've found that most features of Safari dev tools that worked in iOS 17 are broken in iOS 18. Here are the steps I'm taking: Set up a WKWebView with isInspectable = true that loads a local URL, e.g. https://www.local.mydomain.com:3000 Install a self-signed SSL certificate on a simulator for www.local.mydomain.com Run my app on the simulator The WKWebView loads successfully In Safari on my Mac, I can select the WKWebView and open dev tools to inspect it If the simulator is on iOS 17, this works fine, no issues. But if the simulator is on iOS 18, Safari dev tools are mostly broken. I can tell that there is a connection to the WKWebView because the Network tab logs the requests that I expect. But I cannot use any of the other dev tools features: Elements, Sources, Console, etc. Has anyone else encountered this? Is there a workaround?

App Icon created with Icon Composer is empty for visionOS app We are developing a universal app, and the app’s icon was created using Icon Composer. Xcode 26, RC visionOS 26 and visionOS 2.5 App Icons on macOS, iOS, and iPadOS are correct We have archived the app for macOS and iOS and successfully uploaded it to the App Store. This strongly suggests that the App Icon configuration in our project settings is correct for these platforms. App Icon issue on visionOS However, the visionOS app icon is not working as expected: When testing on the Vision Pro simulator (versions 2.x and 26.0), the app icon appears empty. When archiving and submitting to the App Store, the process fails with the following error: The app’s Info.plist file is missing the CFBundleIcons.CFBundlePrimaryIcon key for the visionOS App Icon. This suggests that the project’s App Icon settings may not be correctly applied for visionOS builds. Request for assistance We are preparing to release our app, one of the first to support Liquid Glass, and would greatly appreciate guidance on how to resolve this issue with the visionOS app icon.
