As far as I know, there was a time that you can capture GPU workload for opengles game app on iOS using Xcode. However, currently I'm using Xcode version 15.2 and iOS18，it seems the "capture GPU workload" button is always disabled when I'm trying to debug my game app which is using opengles api for graphics rendering no matter switchinng "GPU Frame Capture" to "OpenGL ES" or "Metal" or "Automatically" in the scheme. And I'm not able to capture GPU workload for my game on iOS. The only way to make the "capture GPU workload" button enabled is creating a new project using metal api for graphics rendering. But I don't want to change the graphics API, because it will cause a lot. Does Xcode still support capturing GPU workload for OpenGLES game app on iOS? If not, is there an alternative way?

let package = Package( name: "MyLibrary", platforms: [.iOS(.v17)], There is no ios26 option. How do I build it under ios26? thanks

Hi! I am getting this error since an xcode update when trying to build my project. Module 'audioplayers' not found (in target 'Runner' from project 'Runner'). Thank you in advance for any help!

Ok, I'm going crazy here. I have a static library for iOS that I want to build for the simulator. I use xcodebuild -destination="iOS Simulator" and then check the library using otool which tells me the platform is 6, which is Mac Catalyst. When I look at the output of xcodebuild, it says --- xcodebuild: WARNING: Using the first of multiple matching destinations: { platform:macOS, arch:arm64, variant:Mac Catalyst, id:00006041-0008492E3AA1801C, name:My Mac } ... It has the simulator listed too, way down the list: { platform:iOS Simulator, arch:x86_64, id:AB7A99B3-8D24-4F73-A42D-9BB45321928D, OS:18.6, name:iPad (A16) } When I put all of that into xcodebuild for the platform, it still says there are multiple matching destinations and chooses Mac Catalyst. Why? How? What? Does platform="iOS Simulator" mean nothing? How in the world does "Mac Catalyst" match "iOS Simulator"????? I don't want Mac Catalyst, I don't need Mac Catalyst, and I can't get rid of Mac Catalyst. Nothing I specify in xcodebuild results in anything I can build that will compile for the simulator. What the heck am I doing wrong?

When upgrading to a new version of Xcode, normally we look in the "Toolchain version history" table of the Xcode wikipedia page. But for Xcode 16.2, it lists git tag swift-6.0.3-RELEASE, which fails to compile with a known error. There was a fix for this error way back on July 4, 2024, but for some reason this fix does not appear in swift-6.0.3-RELEASE (as confirmed with git log, even though the tag occurred on December 2, 2024). So it turns out the minimum tag is swift-6.1-RELEASE for building LLVM with Xcode 16.2 (there are no other release tags between these two). Is it possible that the wikipedia table is simply incorrect in this case? If not, is there a workaround to build swift-6.0.3-RELEASE using Xcode 16.2, as published by Apple?

I am using a script originally developed by Tommy in 2014. It updates the info.plist value for CFBundleVersion. Latest version of Xcode 16.4 modifies the behavior of the script. If I clean the build folder, the value is set by the script that runs after Copy Bundle Resources and modifies the info.plist file in the Debug version of the app. Subsequent runs using the same build seem to execute the script but the info.plist value reverts to the value set in the source directory. The script calculates a value based on the number of revisions to the current branch.

Hi, I compiled Intel Open Image Denoise library for iOS, and obtained a bunch of dependent dylibs. I want to use these ones in a swift project (via bridging as this is C/C++) targeting the iPad. I understand that it is required to embed these dylibs into frameworks as iOS doesn't allow dylib. Is it necessary to generate one framework for each dylib? If so, how are dependencies between the libraries (and their frameworks) managed? Or, is it possible to generate only one framework embeding all the dependencies?

Dear Apple Developer Support, We are experiencing a critical issue after upgrading our development environment from Xcode 15 to Xcode 16 (beta). Our iOS application integrates Flutter via CocoaPods (install_all_flutter_pods and flutter_post_install) and uses plugins like webview_flutter. After the upgrade, our project started failing at the linking stage with the following errors: Undefined symbol: _XPluginsGetDataFuncOrAbort Undefined symbol: _XPluginsGetFunctionPtrFromID Undefined symbol: Plugins::SocketThreadLocalScope::SocketThreadLocalScope(int) Undefined symbol: Plugins::SocketThreadLocalScope::~SocketThreadLocalScope() Linker command failed with exit code 1 These symbols seem to originate from Flutter’s new native C++ plugin architecture (possibly via webview_flutter_wkwebview), and were previously resolving fine with Xcode 15. We have ensured the following: Added -lc++ and -ObjC to OTHER_LDFLAGS Cleaned and rebuilt Flutter module via flutter build ios --release Re-installed CocoaPods with pod install Verified Flutter.xcframework and plugin xcframeworks are present Despite this, the linker fails to resolve the mentioned symbols under Xcode 16. This suggests a stricter linker behavior or a compatibility issue with the new C++ plugin system Flutter uses. Can you confirm: If Xcode 16 introduces stricter C++/Objective-C++ linker constraints? Is there an official workaround or updated documentation for dealing with Plugins::SocketThreadLocalScope and related symbol resolution? Should these symbols be declared explicitly or provided in .xcframework format from plugin developers? We would appreciate guidance or clarification on how to proceed with Flutter plugin compatibility under Xcode 16. Thank you.

I have an AppleTV app which I released in 2016. I've updated it and released a new version every year without much hassle. This year, with tvOS 17.2, the layered app icon isn't working right. This is a two-layer image made with PNGs. When it's selected, it looks right and the layers move correctly: But when it's not selected, the background layer disappears: Screenshots are from the simulator but it also happens on the device. It's inconsistent; sometimes it's the front layer that disappears. Occasionally both layers work, but I can't tell why. I've spent a day trying everything. Very frustrated. The icon previews correctly in Xcode and in Parallax Viewer. The image sizes are correct: 400 x 240 for Small, 800 x 480 for Small@2x, 1280 x 768 for Large. The back layer is a non-transparent PNG. I tried adding a Large@2x set. Didn't help. Originally I had a three-layer image with no middle layer PNG. I deleted the empty middle layer, but that didn't help. All the PNG files are from GnuIMP. Same color space, even. I was using the filenames tvicon-back-s.png and tvicon-back-s@2x.png. I tried taking out the @ sign in case that was confusing Xcode. (It never has before, but I am flailing here.) Anybody have any clues? If it's an Apple bug and there's nothing I can do, I'm going to just push the release button and hope it fixes itself someday.

We are trying to run Xcode 26 Beta 3 in our CI but it gives the following error when trying to install simulators: [04:23:37]: ▸ 2025-07-22 04:23:37.173 xcodebuild[856:11336] [MT] DVTPlugInLoading: Failed to load code for plug-in com.apple.dt.IDESimulatorFoundation (/Applications/Xcode-beta.app/Contents/Frameworks/IDESimulatorFoundation.framework), error = Error Domain=NSCocoaErrorDomain Code=3588 "dlopen(/Applications/Xcode-beta.app/Contents/Frameworks/IDESimulatorFoundation.framework/IDESimulatorFoundation, 0x0109): Library not loaded: /Library/Developer/PrivateFrameworks/CoreSimulator.framework/Versions/A/CoreSimulator [04:23:37]: ▸ Referenced from: <AE950330-CC10-3EA9-8604-F0BACFEAD81B> /Applications/Xcode-beta.app/Contents/Frameworks/IDESimulatorFoundation.framework/Versions/A/IDESimulatorFoundation [04:23:37]: ▸ Reason: tried: '/Library/Developer/PrivateFrameworks/CoreSimulator.framework/Versions/A/CoreSimulator' (no such file), '/System/Volumes/Preboot/Cryptexes/OS/Library/Developer/PrivateFrameworks/CoreSimulator.framework/Versions/A/CoreSimulator' (no such file), '/Library/Developer/PrivateFrameworks/CoreSimulator.framework/Versions/A/CoreSimulator' (no such file)" UserInfo={NSLocalizedFailureReason=The bundle couldn’t be loaded., NSLocalizedRecoverySuggestion=Try reinstalling the bundle., NSFilePath=/Applications/Xcode-beta.app/Contents/Frameworks/IDESimulatorFoundation.framework/IDESimulatorFoundation, NSDebugDescription=dlopen(/Applications/Xcode-beta.app/Contents/Frameworks/IDESimulatorFoundation.framework/IDESimulatorFoundation, 0x0109): Library not loaded: /Library/Developer/PrivateFrameworks/CoreSimulator.framework/Versions/A/CoreSimulator I tried adding everything in the book: xcode-select --switch /Applications/Xcode-beta.app xcodebuild -runFirstLaunch xcodebuild -downloadPlatform iOS But nothing seems to work.

Hi everybody! I am pretty new to app development. I started by creating an app and linking it to Firebase as DB. I had added them directly on Xcode (File>Add Package Dependencies>...). Then I needed one specific package that was not there, so I started using cocoapods (all from the terminal), but it didn't work. When I deleted the ones from cocoapods (I am not 100% sure I deleted everything I had to), I started using the packages in the first way, but now it doesn't even build with the packages I have. I checked many times and I actually have those packages, but it does not work at all. Any suggestions on how to solve it or who I could contact? Thanks.

Hi I'm using Xcode 16.4 on a Mac mini m4 so please let's not get in the weeds about latest this or that for software, etc... I'm trying to move one of the tab bar items in the controller, the home item, the the far left and I can grab it and drag it but it won't drop anywhere except where it exists. the other items won't move either. I've googled this and not finding anything stating you have to do a key combo, etc... which I've tried the command, option and control keys each with the dragging. Also the ability to actually select and item to drag it is extremely inconsistent, sometimes it grabs it and most of the time it doesn't. do I need to just delete the connectors and add them back in the proper order? is that really the solution here?

I used Xcode to upload to App Store Connect, and I only clicked "Distribute App" once, but the build was uploaded to TestFlight twice, resulting in build numbers 356 and 357 ( I need 356 ). But this doesn’t happen every time. Why would this happen?

Ok, I have a bit of special problem. I want to use the "Swift Upcoming Feature Flags" in my packages. The problem is that we have quite a lot of Packages in a quite deep tree: at the root of the Package directory there are four dirs: AppA/ AppB/ Shared/ Temporary/ also the packages ExternalLibs and BuildPlugins. Temporary contains Packages that need rework and the other three subdirs each contain the subdirs: Features/ Utilities/ Services/ All in all there are over 100 packages. Now I would like to use definitions like https://github.com/treastrain/swift-upcomingfeatureflags-cheatsheet to use in the Package.swift files. And as you might guess, I do not want to copy those into each and every Package.swift file. It seems like SPM is only finding includes by itself if they are in the exact same directory as the Package.swift file 🙄 That's not at all helpful… Has anyone found a way to do useful includes into Package.swift files? Any help appreciated. Thank You Roddi

Hey everyone, I'm encountering an issue when trying to run my iOS application, which integrates a Unity project, on the iOS Simulator. I'm consistently getting a dlopen error 232 related to UnityFramework.framework. The full error message is: Error loading ...UnityFramework.framework/UnityFramework (232): dlopen(...UnityFramework.framework/UnityFramework, 0x0109): tried: '...UnityFramework.framework/UnityFramework' (mach-o file (...UnityFramework.framework/UnityFramework), but incompatible platform (have 'iOS', need 'iOS-sim')) It seems like the UnityFramework.framework is built for a physical iOS device (ARM architecture), but the simulator requires a different architecture (x86_64 for Intel Macs or arm64 for Apple Silicon Macs). I've already tried: Cleaning the build folder in Xcode. Checking the "Frameworks, Libraries, and Embedded Content" settings in my target's General tab. Could anyone provide guidance on how to properly configure my Unity build or Xcode project to ensure UnityFramework.framework includes the necessary simulator architectures? Any specific build settings in Unity or Xcode, or steps to re-export/re-integrate the framework, would be greatly appreciated! Thanks in advance for your help!

PLATFORM AND VERSION Development environment: Xcode 16.4 (16F6), macOS 15.5 (24F74) Run-time configuration: iOS 18.3.1 DESCRIPTION OF PROBLEM I cannot build my app due to a module not found error when I'm importing Sample-Swift.h header to an ObjectiveC file. I need to use Swift code to ObjectiveC file with Swift code using an external XCFramework. It seems to be related to a mix with ObjectiveC and Swift code when Swift code uses class inheritance from FZWorkoutKit class. With a full Swift project, no issue. STEPS TO REPRODUCE Project https://fizzup.s3.amazonaws.com/files/public/Sample-WK.zip Open the provided project and try to build it. The issue occurs. In MyObject.m file, if you comment the first import (Sample-Swift.h), no issue occurs but I cannot use my Swift code (MyFile class). Uncomment the line commented in step 1. Go to MyFile.swift and change class inheritance from GoModeController (from FZWorkoutKit framework) to UIView (from UIKit). No issue occurs.

Do simulators match real device for pixel density for testing image assets?

Hi guys, i have an issue with my app, i am able to view in app purchase products from my deployed hybrid app (Ionic 8 with Capacitor 7) IOS platform. My inapp products are displaying on real device os 18.5 but on simulators there are no products. Is there a bug or something. Simulators tested 16 Pro max iPad m4, and iPad 5th gen all 18.5 other versions below the products does show and on real device. Your assistance will be much appreciated.
