I've been using XCode for development in C++ for several years. Suddenly, today it started having the following problem: Any time I try to compile my code, (even if I just finished successfully compiling it), it spends several minutes running CLangStatCache. This is according to the result of "Perform Action... Build with Timing Summary". Furthermore, if I first delete the ".../DerivedData/SDKStatCaches.noindex" folder, the problem goes away and it compiles immediately. However, it creates a new folder with a 32 Mb file in it, and then has the same problem the next time unless I delete that folder again. I do not want to have to delete this file every time I compile my code. Is there some way to turn this off? What happened that is different today from any other day in the last several years? I did just download and install the latest System software update, including XCode... Did that break something?

I started using on-demand resources for some data assets. After that, the Swift Asset Symbol Extension feature began to fail in the Xcode editor. Even though the app builds and runs fine, the Xcode editor shows errors, indicating that there is no extension variable for my color and image assets. I submitted feedback and updated it after each new Xcode release. However, I have not received any responses, and the problem persists. The Xcode versions I tested: 15.3, 15.4, 16.1, 16.2, 16.3 Steps to reproduce this error: Create a new app project (SwiftUI, Swift). Create a new color asset named "myBackground." In ContentView, add a background modifier to a view: .background(Color.myBackground). Auto-completion will work, and there are no issues. Create a new data asset named "myData." Add the "On Demand Resource" tag to "myData" with the tag "some_tag." Create a new color asset named "myOtherBackground" and make its color different from "myBackground." In ContentView, try to replace the background with Color.myOtherBackground. It will not be listed in auto-completion and will show the error "Type 'Color' has no member 'myOtherBackground.'" However, it will still compile and show "myOtherBackground" in the preview, simulator, or on the device. You will start to see the failed "Project Build Preparation" report in the Reports Navigator in Xcode. According to the report, the "GenerateAssetSymbols" command fails. Error message: GenerateAssetSymbols /Users/***/Projects/***/***/Assets.xcassets (in target '***' from project '***') cd /Users/***/Projects/*** /Applications/Xcode_15.3.app/Contents/Developer/usr/bin/actool --output-format human-readable-text --notices --warnings --export-dependency-info /Users/***/Library/Developer/Xcode/DerivedData/***-***/Index.noindex/Build/Intermediates.noindex/***.build/Debug-iphonesimulator/***.build/assetcatalog_dependencies --output-partial-info-plist /Users/***/Library/Developer/Xcode/DerivedData/***-***/Index.noindex/Build/Intermediates.noindex/***.build/Debug-iphonesimulator/***.build/assetcatalog_generated_info.plist --app-icon AppIcon --accent-color tint --compress-pngs --enable-on-demand-resources YES --development-region en --target-device iphone --minimum-deployment-target 15.0 --platform iphonesimulator --asset-pack-output-specifications /Users/***/Library/Developer/Xcode/DerivedData/***-***/Index.noindex/Build/Intermediates.noindex/***.build/Debug-iphonesimulator/***.build/AssetPackOutputSpecifications.plist --compile /Users/***/Library/Developer/Xcode/DerivedData/***-***/Index.noindex/Build/Products/Debug-iphonesimulator/workoutai.app /Users/***/Projects/***/***/Assets.xcassets --bundle-identifier *** --generate-swift-asset-symbols /Users/***/Library/Developer/Xcode/DerivedData/***-***/Index.noindex/Build/Intermediates.noindex/***.build/Debug-iphonesimulator/***.build/DerivedSources/GeneratedAssetSymbols.swift --generate-objc-asset-symbols /Users/***/Library/Developer/Xcode/DerivedData/***-***/Index.noindex/Build/Intermediates.noindex/***.build/Debug-iphonesimulator/***.build/DerivedSources/GeneratedAssetSymbols.h --generate-asset-symbol-index /Users/***/Library/Developer/Xcode/DerivedData/***-***/Index.noindex/Build/Intermediates.noindex/***.build/Debug-iphonesimulator/***.build/DerivedSources/GeneratedAssetSymbols-Index.plist /* com.apple.actool.errors */ : error: Could not create a NSArray from '/Users/***/Library/Developer/Xcode/DerivedData/***-***/Index.noindex/Build/Intermediates.noindex/***.build/Debug-iphonesimulator/***.build/AssetPackOutputSpecifications.plist'. : error: Not enough arguments provided; where is the input document to operate on?

I implemented the cloudkit function, where users can connect with each other. The problem is, that if User A is doing a friend request and User B is accepting the request. The friend entry is correct visible for User B but not for User A. I can see in cloud kit that after the accepted request, the friend connection is set up correctly, also with the correct userID, but it not showing up for User A (the one that send the request) It's in the public database. In this view you sign in using Apple Sign-In and create a specific user ID. Then you can access a global leaderboard to compare with all signed-in users. Additionaly, there’s a friend tab where you can search for and type in a specific user ID. The target user sees the friend request, can accept it, and then the accepted friend appears in their friend list. However, the original requester doesn’t see the connection after acceptance even though CloudKit shows the records Add comment. I've also tried to add a placeholder in for User A, that e.g he send the request and then has a placeholder where it says e.g pending request to User B. After User B accepted the request, the placeholder will go away and no friend connection is displayed, very strange.

I'm on version 16 of simulator and Xcode. Last Friday, starting the simulator would take 10 seconds at the most. Now, it takes at least 10 minutes. My app target is the same and nothing in my app itself has changed. There's no new software installed and it has plenty of RAM and disk. When I target my phone, it is instant. So I'm testing / debugging everything on my phone now. When I use the simulator, the initial load is about 10 minutes, then it's fine (using the app itself). But something is causing it to hang when loading. And like I said - last week it was fine. If it was slow when running on my phone, I'd think it was something with me/the app. But it's not. This is the only messages I get in the system log.

I work on an iOS app, written in Objective-C and C++, that uses a static library. I build this library using a Run Script in Build Phases in Xcode. This is a fat library, containing arm64 code built for iPhoneOS, and x86_64 code built for iPhoneSimulator. I'm trying to figure out how to create an arm64 iPhoneSimulator build of my app, and I'm running into a problem. If I simply enable arm64 debug builds, I get an error message saying "building for iOS Simulator, but linking in object file built for iOS", indicating that the arm64 iPhoneOS code in the library is not compatible with an arm64 iPhoneSimulator target. Now, I can build the library as arm64 for iPhoneSimulator, but that means I'll have to build a separate library for the simulator build, since lipo won't combine arm64 iPhoneOS and arm64 iPhoneSimulator builds in one file. My question: how can I get Xcode to link with a different library for iPhoneSimulator builds than for iPhoneOS builds? All I can come up with is to use completely separate targets for debugging in the simulator vs. debugging on a real device, but that seems ugly. (It would be even better if I could use the same library for both arm64 iPhoneSimulator and iPhoneOS builds. The library in question is a math library which makes no system calls, so I think the same code should be usable for both builds, if only I could get the linker to allow that.)

Hi there - when attempting to upload the latest build of my macOS app to App Store Connect via Xcode's Organizer I'm now greeted with this warning. I don't even know what it's attempting to tell me.. Yes, I understand what dSYMs are for - but the UUIDs don't appear anywhere in my workspace (full text search on the folder), in the build log, or the ..thing.. the 'Export' button generates. Any help much appreciated, ATM I don't even know where to start. Cheers, Jay

I can't get my app's logo to show in the "About" box nor in the app switcher. I have: created "Assets.xcassets" created "AppIcon" added 10 image files of the logo to the AppIcon image well [? right terminology ?] saved and built the project – there are no errors or warnings When I run the project, I still get the default image showing in the About box and in the app switcher. Because first attempt failed, I changed "applet" to "AppIcon" in "App Icons and Launch Screen" in "General" settings. That did not change the result. I also toggled "Include all app icon assets" which also did not change the result. Weirdly, my app's logo DOES show beside the app name in every item of "Build Settings". Do I need to do something else to change the default image in the "About" box ? Thanks. [Xcode 16.2 on macOS 15.3.2.]

I’ve developed an Apple Watch extension for an existing iOS app. When I run the app on the watch via Xcode using the simulator, everything works fine. However, when I try to install it on my iPhone, the Watch app doesn’t show it in the "Available Apps" list, so I can't install it on the watch. The Apple Watch is connected to my iPhone, and I can see other apps available for installation without any issues. I also created a brand new project with watchOS support to troubleshoot, but the same problem occurred. Any ideas on how to resolve this?

Hello everyone, I’m encountering an issue when trying to build and archive my library BleeckerCodesLib using Swift Package Manager. My project is structured with two targets: CBleeckerLib: A C target that contains my image processing code (C source files and public headers). BleeckerCodesLib: A Swift target that depends on CBleeckerLib and performs an import CBleeckerLib. Below is the relevant portion of my Package.swift: // swift-tools-version:5.7 import PackageDescription let package = Package( name: "BleeckerCodesLib", platforms: [.iOS(.v16)], products: [ .library(name: "BleeckerCodesLib", targets: ["BleeckerCodesLib"]) ], targets: [ .target( name: "CBleeckerLib", publicHeadersPath: "include" ), .target( name: "BleeckerCodesLib", dependencies: ["CBleeckerLib"] ) ] ) Directory Structure My project directory looks like this: BleeckerCodesLib/ ├── BleeckerCodesLib.xcodeproj/ │ └── xcuserdata/ │ └── robertopitarch.xcuserdatad/ │ └── xcschemes/ │ └── xcschememanagement.plist ├── BleeckerCodesLib.h ├── Package.swift └── Sources/ ├── CBleeckerLib/ │ ├── bleecker-lib.c │ └── include/ │ ├── bleecker-lib.h │ └── CBleeckerLib.h └── BleeckerCodesLib/ ├── UIImage+Extensions.swift ├── ImageProcessingUtility.swift ├── APIManager.swift ├── BleeckerCodesLib.swift ├── CameraView.swift ├── RealTimeCameraView.swift └── BleeckerCameraWrapper.swift Code Example In my Swift code (for example, in BleeckerCodesLib.swift), I import the C module as follows: import SwiftUI import UIKit import CBleeckerLib // Import the C module public struct BleeckerCodes { public struct DetectedCode { public let code: String public let corners: [CGPoint] public init(code: String, corners: [CGPoint]) { self.code = code self.corners = corners } } // Initialization function public static func initializeLibrary() -> String { bleecker_init() // Call the C module function return "BleeckerCodesLibrary initialized!" } // ... other functions } The Problem When I try to compile or archive the project using commands such as: xcodebuild archive -project BleeckerCodesLib.xcodeproj -scheme BleeckerCodesLib -destination "generic/platform=iOS" -archivePath "archives/BleeckerCodesLib" I receive the error: "no such module 'CBleeckerLib'" Any assistance or step-by-step guidance on resolving this integration issue would be greatly appreciated.

iOS simulator way slower to launch after updating to Xcode Version 16.2 (16C5032a). macOS 15.3.1 (24D70) MacBook Air M1, 8GB

Hello everyone, I’m facing an issue with running my app on my iPhone, and I’m hoping someone can help. Here’s my situation: I’m using Xcode 14.3.1 on macOS Ventura 13.7.4. My iPhone is running iOS 18.3.2 (Model: iPhone 14 Pro). When I connect my iPhone to Xcode, I get the error: "Could not locate device support files. You may be able to resolve the issue by installing the latest version of Xcode from the Mac App Store or developer.apple.com." I understand that Xcode 14.3.1 only supports up to iOS 16.4, and my iPhone’s iOS 18.3.2 is much newer. Unfortunately, I cannot update my macOS to Sonoma (14.x) due to hardware limitations, so I cannot install a newer version of Xcode (like 15.x or 16.x) that supports iOS 18.3.2. I’ve tried adding device support files manually, but the repositories I found (e.g., iGhibli/iOS-DeviceSupport and JinjunHan/iOSDeviceSupport) only have files up to iOS 16.4 or 17.3, and they don’t work for iOS 18.3.2. Does anyone have the device support files for iOS 18.3.2 (or a close version like 18.3) that I can add to my Xcode 14.3.1 to make it work with my iPhone? Alternatively, does anyone know a reliable source where I can download these files? Any other suggestions to resolve this issue without upgrading my macOS would be greatly appreciated! Thank you in advance for your help! [Your Name or Username]

Hi. I have a xcframework that has a dependency on 'RxSwift' and 'RxCocoa'. I deployed it using SPM by embedding it in a Swift Package. However when I import swift package into another project, I keep getting the following error: "Missing required module 'RxCocoaRuntime" How can I fix this? Below are the steps to reproduce the error. Steps Create Xcode proejct, make a dependency on 'RxSwift' and 'RxCocoa' (no matter doing it through tuist or cocoapods) Create XCFramework from that proejct. (I used commands below) xcodebuild archive \ -workspace SimpleFramework.xcworkspace \ -scheme "SimpleFramework" \ -destination "generic/platform=iOS" \ -archivePath "./SimpleFramework-iphoneos.xcarchive" \ -sdk iphoneos \ SKIP_INSTALL=NO \ BUILD_LIBRARY_FOR_DISTRIBUTION=YES xcodebuild archive \ -workspace SimpleFramework.xcworkspace \ -scheme "SimpleFramework" \ -archivePath "./SimpleFramework-iphonesimulator.xcarchive" \ -sdk "iphonesimulator" \ SKIP_INSTALL=NO \ BUILD_LIBRARY_FOR_DISTRIBUTION=YES xcodebuild -create-xcframework \ -framework "./SimpleFramework-iphoneos.xcarchive/Products/Library/Frameworks/SimpleFramework.framework" \ -framework "./SimpleFramework-iphonesimulator.xcarchive/Products/Library/Frameworks/SimpleFramework.framework" \ -output "./SimpleFramework.xcframework" Embed in Swift Package, and deploy. // swift-tools-version: 6.0 // The swift-tools-version declares the minimum version of Swift required to build this package. import PackageDescription let package = Package( name: "SimplePackage", platforms: [.iOS(.v16)], products: [ .library( name: "SimplePackage", targets: ["SimplePackage"]), ], dependencies: [ .package(url: "https://github.com/ReactiveX/RxSwift", from: "6.8.0") ], targets: [ .binaryTarget( name: "SimpleFramework", path: "Sources/SimpleFramework.xcframework" ), .target( name: "SimplePackage", dependencies: [ "SimpleFramework", "RxSwift", .product(name: "RxCocoa", package: "RxSwift") ] ) ] ) Download Swift Package in another project and import module. I resolved this by removing dependencies from the Swift Package, downloading package in another project, and fetching dependencies by cocoapods. Thist works, but I don't want to use another dependency manager while using SPM. Development Environment CPU : Apple M4 Max MacOS : Sequoia 15.3 Xcode : 16.2

I am currently developing a No-Sandbox application. What I want to achieve is to use AuthorizationCopyRights in a No-Sandbox application to elevate to root, then register SMAppService.daemon after elevation, and finally call the registered daemon from within the No-Sandbox application. Implementation Details Here is the Plist that I am registering with SMAppService: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Label</key> <string>com.example.agent</string> <key>BundleProgram</key> <string>/usr/local/bin/test</string> <key>ProgramArguments</key> <array> <string>/usr/local/bin/test</string> <string>login</string> </array> <key>RunAtLoad</key> <true/> </dict> </plist> Code that successfully performs privilege escalation (a helper tool popup appears) private func registerSMAppServiceDaemon() -> Bool { let service = SMAppService.daemon(plistName: "com.example.plist") do { try service.register() print("Successfully registered \(service)") return true } catch { print("Unable to register \(error)") return false } } private func levelUpRoot() -> Bool { var authRef: AuthorizationRef? let status = AuthorizationCreate(nil, nil, [], &authRef) if status != errAuthorizationSuccess { return false } let rightName = kSMRightBlessPrivilegedHelper return rightName.withCString { cStringName -> Bool in var authItem = AuthorizationItem( name: cStringName, valueLength: 0, value: nil, flags: 0 ) return withUnsafeMutablePointer(to: &authItem) { authItemPointer -> Bool in var authRights = AuthorizationRights(count: 1, items: authItemPointer) let authFlags: AuthorizationFlags = [.interactionAllowed, .preAuthorize, .extendRights] let status = AuthorizationCopyRights(authRef!, &authRights, nil, authFlags, nil) if status == errAuthorizationSuccess { if !registerSMAppServiceDaemon() { return false } return true } return false } } } Error Details Unable to register Error Domain=SMAppServiceErrorDomain Code=1 "Operation not permitted" UserInfo={NSLocalizedFailureReason=Operation not permitted} The likely cause of this error is that /usr/local/bin/test is being bundled. However, based on my understanding, since this is a non-sandboxed application, the binary should be accessible as long as it is run as root. Trying post as mentioned in the response, placing the test binary under Contents/Resources/ allows SMAppService to successfully register it. However, executing the binary results in a different error. Here is the plist at that time. <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Label</key> <string>com.example.agent</string> <key>BundleProgram</key> <string>Contents/Resources/test</string> <key>ProgramArguments</key> <array> <string>Contents/Resources/test</string> <string>login</string> </array> <key>RunAtLoad</key> <true/> </dict> </plist> Here is the function at that time. private func executeBin() { let bundle = Bundle.main if let binaryPath = bundle.path(forResource: "test", ofType: nil) { print(binaryPath) let task = Process() task.executableURL = URL(fileURLWithPath: binaryPath) task.arguments = ["login"] let pipe = Pipe() task.standardOutput = pipe task.standardError = pipe do { try task.run() let outputData = pipe.fileHandleForReading.readDataToEndOfFile() if let output = String(data: outputData, encoding: .utf8) { print("Binary output: \(output)") } task.waitUntilExit() if task.terminationStatus == 0 { print("Binary executed successfully") } else { print("Binary execution failed with status: \(task.terminationStatus)") } } catch { print("Error executing binary: \(error)") } } else { print("Binary not found in the app bundle") } } Executed After Error Binary output: Binary execution failed with status: 5 Are there any other ways to execute a specific binary as root when using AuthorizationCopyRights?

Hi everyone, I’m trying to detect if Developer Mode is enabled on iOS 16+ devices using Swift but haven’t found any official APIs or documentation for this. Are there Apple-recommended ways to achieve this, or is it restricted for privacy/security reasons? Thanks!

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 create a screentime app using the Family Controls as well as Device activity frameworks. The build succeeds but while pushing to an iphone we are getting an info.plist file for deviceactivity.framework could not be found error. For reference when using the Screentime API a physical device must be used not a simulator. When we remove the device activity framework this error also occurs for the family controls framework. We have added the Family Controls(development) Capability and applied for the distribution capability. We have redownloaded xcode multiple times on the main device, deleted derived data, and redownloaded all of the iphone SDKs and the issue still persists.

Hi, I have a project that is based on a GPL library. The GPL library has some issue since early 2024 that requires it to be run on XCode 15.2. Any XCode above 15.2 will only give you "Invalid MinimumOSVersion." and "Missing Info.plist value." errors. So I installed 15.2 again. But now I have another problem because it can only run on Ventura. How do I run XCode 15.2 on my Sequoia MacOS? I hate to reinstall the OS all again. Thank you.
