I am trying to run Xcode 15 on macOS 15.4. As we need to build framework with older versions of Xcode. Any work around for it?

With Xcode 14, the device selection on the bottom of the storyboard canvas has changed, and the iPhone 12 and 13 mini screens are no longer there, as well as there only being one model of iPad. Is there a way to add more devices to this section? I have simulators installed for these devices, and this is the way I've been checking compatibility so far, but this is not sustainable. I appreciate any help that you can give me.

As subject, after update to Xcode 26.0.1, none of the simulator able to download, tried click the Get button, tried run command in terminal, all failed. Error from terminal: xcodebuild -downloadPlatform iOS Finding content...

I have an iOS app with a QuickLook extension. I also added Apple Vision Pro in the target's General > Supported Destinations section. About one year ago, I was able to run the app on iPhone, iPad and Apple Vision Pro Simulators. Today I tried running it again on Apple Vision Pro with Xcode 26.0.1, but Xcode shows this error: Try again later. Appex bundle at ~/Library/Developer/CoreSimulator/Devices/F6B3CCA8-82FA-485F-A306-CF85FF589096/data/Library/Caches/com.apple.mobile.installd.staging/temp.PWLT59/extracted/problem.app/PlugIns/problemQuickLook.appex with id org.example.problem.problemQuickLook specifies a value (com.apple.quicklook.preview) for the NSExtensionPointIdentifier key in the NSExtension dictionary in its Info.plist that does not correspond to a known extension point. I tried again later a couple times, even after running Clean Build Folder Immediately, without any change. I can reproduce this with a fresh Xcode project to which I add a Quick Look Preview Extension and Apple Vision Pro as a supported destination. The error doesn't happen when running on Apple Vision Pro (Designed for iPad) or iPad Pro 13-inch (M4) destinations. What is the problem? I created FB20448815.

Everytime when iOS simulator is launched I het a lot of repeated "*** quit unexpectedly" alerts. Where "***" is a mix of "managedappdistributiond","healthappd", and "findmylocated" Even after the simulator is launched I still het random "*** quit unexpectedly" alerts. Very annoying because the alerts deactivates the active window This is on an MacBook Pro M3 Max,, Xcode 15.2, Sonoma 14.2.1, it also happens with Xcode 15.1 A co developer (MacBook Pro M1 Max,Xcode 15.2, Sonoma 14.2.1) does not have the issue Any idea how I can prevent this from happening? Update Every mentioned service crash happens in libswiftCore.dylib at 0x1929f3938 assertionFailure(:_:file:line:flags:) + 248

The Files app in the iOS 18 beta simulator appears to be read-only. I am unable to: create folders copy files into it by dragging them from macOS safe files from safari I have been unsuccessful at finding a way to popular any file or folder in the Files app which is preventing me from testing some scenarios in my app where I import files using the files sheet. The earliest I tried was beta 3 and it still persists in beta 7. The iOS 17 simulator works fine in comparison. My mac is a 2019 macbook pro running Sonoma 14.5. To reproduce: New folder Launch Files app in iOS simulator Tap into "On my phone" From the top menu tap "New Folder" (nothing happens) Download a file Launch safari Find a file like a PDF to download Tap on the down arrow in the toolbar Files opens up with the filename in the textfield at the bottom The "Save" button is grayed out. Copy from macOS Open the Files app in iOS and browse to a local folder drag a file from the macbook onto the simulator the sheet appears with the filename in the text field The "Save" button is grayed out

When I update the macOS from 15.5 to 15.6, Preview error. 1、I try remove simulator cache， sdk 2、remove Xcode build cache 3、reinstall Xcode 4、try with this method https://byby.dev/uninstall-xcode#:%7E:text=Delete%20old%20simulators%20and%20devices,moving%20them%20to%20the%20Trash but all failed swiftui log.txt

I use Carthage to build a set of dependencies. I generate .xcframework files with code for both macOS and iOS. This works through Xcode 26 beta 4. With Xcode 26 beta 5, the resulting .xcframework files seem to have code only for iOS, not macOS. Each framework has a ios-arm64 directory and a ios-arm64_x86_64-simulator directory, but no macos-arm64_x86_64 directory. This is affecting 3 of my 7 cross-platform dependencies that I compile with Carthage. What those 3 seem to have in common is that each has one target and scheme for the shared library – instead of one for iOS and another for macOS. I may have to create a second scheme and target in each of these dependencies, or move to SPM. But I am wondering if anyone has another suggestion. Thank you. John

Beginning April 24 releasing on the App Store requires using Xcode 16, iOS 18 SDK. https://developer.apple.com/news/upcoming-requirements/?id=02212025a Xcode only offers simulators for iOS 15. I had not been able to install and use previous versions. Does it imply iOS 15 is the minimum target allowed?

I have a multi target project where every target relies on a built "web bundle" which is basically a collection of html, optimized images, and optimized javascript. Right now that web bundle is built in a pre build step by running a script. The script takes awhile to run and outputs to a folder that is referenced into the project via a PBXFileReference which is then referenced in the Copy Bundle Resources step. 96516AC22BF928DD00576562 /* build */ = {isa = PBXFileReference; lastKnownFileType = folder; name = build; path = "../web-ui/build"; sourceTree = "<group>"; } .... 96516AC32BF928DD00576562 /* build in Resources */ = {isa = PBXBuildFile; fileRef = 96516AC22BF928DD00576562 /* build */; }; As a step, I wrote an aggregate target that can also run this script. I specified its input and output files and turned off sandboxing. It does exactly what I need it to. Critically it is ran based on dependency analysis. If I modify any file in web-ui it rebuilds, if I dont I can repeatedly build the aggregate target and it will not re-run the script. This is perfect. A97590172E419CBA00741928 /* Build Web Bundle */ = { isa = PBXShellScriptBuildPhase; buildActionMask = 12; files = ( ); inputFileListPaths = ( ); inputPaths = ( "$(SRCROOT)/xcodescripts/build-web-bundle.bash", "$(SRCROOT)/web-ui/index.html", "$(SRCROOT)/web-ui/vite-env.d.ts", "$(SRCROOT)/web-ui/vite.config.ts", "$(SRCROOT)/web-ui/tsconfig.json", "$(SRCROOT)/web-ui/stats.html", "$(SRCROOT)/web-ui/postcss.config.js", "$(SRCROOT)/web-ui/package.json", "$(SRCROOT)/web-ui/justfile", "$(SRCROOT)/web-ui/src/", ); name = "Build Web Bundle"; outputFileListPaths = ( ); outputPaths = ( "$(SRCROOT)/web-ui/build/", ); runOnlyForDeploymentPostprocessing = 0; shellPath = /bin/sh; shellScript = "exec \"${SCRIPT_INPUT_FILE_0}\"\n"; }; You may notice I reference a src file. This is made possible via a flag USE_RECURSIVE_SCRIPT_INPUTS_IN_SCRIPT_PHASES which allows Xcode to check folder dependencies recursively. The problem is that my other targets do not automatically recognize that they need to run the "WebBundle" aggregate target in order to update a resource they copy in their "Copy bundle resources" phase. So I tried adding it as a Target Dependency. A9DE685B2E41C9A8005EF4E0 /* PBXTargetDependency */ = { isa = PBXTargetDependency; target = A97590132E419C1200741928 /* WebBundle */; targetProxy = A9DE685A2E41C9A8005EF4E0 /* PBXContainerItemProxy */; }; Unfortunately this breaks whatever magic was allowing the script to be run only when there are web bundle changes. Every build it runs the "Build Web Bundle" script. I think what I am missing is a way to specify in these other targets that a resource they are used to copying from the Xcode PBXFileReference is produced by the aggregate target. This way they can start to reason about the dependencies. Other possibilities are that I should be building the web bundle to a separate location. Or that these references are somehow broken in another way. To be clear the folder format is as thus project/ iOS/ client.xcodeproj web-ui/ build/ (web bundle build is output here and referenced relatively) src/ index.html (and other things)

Starting Xcode 14, iOS Simulator is able to communicate with APNs in order to register for notification in the sandbox environment. I created a sample test for this. A dumb iOS application that registers for notifications. It has UITests to automatize the tap on the consent popup (it is not possible to ask for the permission via CLI sadly). Once the application registers, the AppDelegate method didRegisterForRemoteNotificationsWithDeviceToken is called and the device token is sent to a local server application (node.js). The test itself creates an iOS 18.6 Simulator with xcrun simctl, builds such app and run the tests through through CLI with xcodebuild. Running this on my personal Macbook Pro M1 2021 goes well every time, so I wanted to bring it on Github Actions (arm64 macOS machines), in order to test the works on a open source library I'm building (hapns). Contacting Github support led me to test this on a macOS image running inside a VM inside a Veertu Anka container on my personal Macbook Pro, due to an VM architectural limit suspicion. The results were the same: iOS simulator isn't able to receive the device token. Not even didFailToRegisterForRemoteNotificationsWithError is called (tested through some network probes-requests that communicate to the server which checkpoints the process reached). So, as asked, I've setup a repro-case to be run in the VM and I've collected VM diagnostics ready to be tested and attached. Does anyone know if there is some unspecified (or specified but buried in the documentation) limit for this? Thanks. Github discussion link for further details, repro-case and so on: https://github.com/actions/runner-images/issues/12747

Anyone else notice that Xcode 16.1 seems to have stopped building universal binaries for both debug and release builds even though under "Build Settings-Build Active Architecture" both Debug and Release are set to NO. We had been using the universal binary builds out of Debug for preliminary tests on Intel based machines. The Architectures setting is set to: Standard Architectures (Apple Silicon, Intel) - $(ARCHS_STANDARD). I started a brand new empty app and it does the same thing. A workaround is to set the Destination in Xcode's menu bar to "Build on Any Mac" and then find the binary and drag it to the Intel computer. You can't run that one though from Xcode. Another workaround is to build an Archive and drag that one.

I have spent nearly an hour trying to get my iPhone 7 with iOS 15.8 to be recognized within xCode 26. I did not have this issue with the previous version of xCode. I have tried rebooting my Mac, rebooting my iPhone 7, removing the iPhone 7 from the list of devices that belong to my account, verified that I have support files for iOS 15.8 installed, signing out of my Apple account and signing back in....nothing works. Every time I go to "Windows > Devices" I see the iPhone 7, but I get a never-ending spinning circle next to the iPhone 7 (which is shown as connected) along with a banner that says "xCode will continue when Joe's iPhone 7 is finished." I can leave the phone connected to my Mac for an hour, and this message and the spinning circle next to the iPhone 7 never changes.

Hi Apple Developer Community. I have a problem with opening my Xcode File in Xcode 16. It says, that a specific File is missing and I don't know how to resolve this. Can someone help me? Thanks for the help :)

I downloaded the Xcode Beta 3 on my MacBook Pro M4 Base today and tested out some iOS26 mechanics of my app. And when I came back to my main Xcode to continue developing in iOS18, I couldn't build my app. I went to Product &gt; Destination &gt; Manage run destinations and then tried to create a simulator with iOS18 but it didn't show up, only choice that's showing up was iOS26. I tried deleting iOS18 platform and downloading it again but it didn't solve, I tried deleting Xcode Beta but it didn't solve the problem either. I deleted Runtimes folder, it didn't solve too. I can not create a simulator of iOS18 or below too, the error says "The iOS 18.5 simulator runtime is not available. Try reinstalling Xcode or the simulator runtime." How can I fix this problem?

I'm trying to bring up an existing macOS app workspace to build against the macOS 26 SDK, however Xcode 26b1 is producing the following error, and I'm unable to proceed: /Users/tonyarnold/Documents/Reveal/<unknown>:1:1: error reading '/Applications/Xcode-beta.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang/17/include/module.modulemap': No such file or directory /Users/tonyarnold/Documents/Reveal/<unknown>:1:1: failed to emit precompiled module '/Users/tonyarnold/Library/Developer/Xcode/DerivedData/ModuleCache.noindex/_Builtin_stdbool-LVR359SH1U4537HG9T3JOGN.pcm' for module map '/Applications/Xcode-beta.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang/17/include/module.modulemap' I've checked and the module map that it claims is missing is there on the filesystem. Is this a known issue with this beta?

Hi everyone, I’ve run into a strange issue while building my app with Xcode 26 beta 6 (targeting iOS 26). When I include an app icon created using Icon Composer, the build time jumps to over 5 minutes. During this time, I noticed that a utility called AssetCatalogSimulatorAgent is consuming a significant amount of CPU. If I remove the Icon Composer-generated icon from my target, the build completes in about 40 seconds. This behavior is consistent across multiple builds. Has anyone else experienced this? Is there a known workaround or optimization for icons created with Icon Composer? I’d love to keep using the new icon format, but the build time is becoming a real bottleneck. Thanks in advance!

Canvas Previews (targeting macOS) in both Xcode 16.4 & Xcode 26 fail to load, when the project imports a Swift package that imports and uses WebKit. I'm on macOS 15.5. Tried also to bring minimum targets of both the project and the package to 15.0. I see that there are some work-arounds for iOS simulator but nothing for the Mac. Anyone facing the same problem?

This is the Icon Composer from Xcode 26.0 Beta 1 (not the really old one Xcode6? 😆 that I find when I search here) Is there a way to show the really cool 3D that they showed off during demos? Maybe all we get is which level is on top. Upon export it only seems to be able to do 2x? - is there some way to get it to take 1x? Every time I change it - it jumps back to 2x and iOS wants 1x... maybe a feedback. Also Xcode seems to want 3 icons - but there are 6 iOS ones exported. How do I get the other 3 in there? It does seem pretty easy to import PNG's from Sketch and order them and move pieces around. I guess you can save individual lighting for each icon mode.
