I understand that mastering essential English skills is fundamental for developers. However, as a Chinese developer, having an IDE with a Chinese interface when encountering Xcode operational issues can absolutely make development work twice as effective with half the effort. A native-language interface environment allows us to focus all our energy on project development. Xcode exists as our development “tool” to facilitate our work, not as another knowledge point requiring study—which could waste significant effort. Don't let an interface turn our beloved tool into a burden. Translated with DeepL.com (free version)

Did DYLD_PRINT_STATISTICS stop working? I am using Xcode 26.0.1 and have tried it on several simulators and real devices, but am not getting any output. I haven't used this environment variable in a few years so don't know when it might have stopped working. Has it been superseded or replaced?

I am developing a binary SDK for consumption by others. When we updated to Xcode 26, any builds which are generated cannot be consumed by Xcode 16. The specifics lie in the optionals. The following Swift code generate a .swiftmodule func affectedApi() -> Int? { return 1 } In Xcode 16 it generated the following .swiftmodule in the framework. public func affectedIntApi() -> Swift.Int? In Xcode 26 it adds an "if" statement. #if compiler(>=5.3) && $NonescapableTypes public func affectedIntApi() -> Swift.Int? #endif That if statement prevents Xcode16 from seeing the API, and it causes compile failures. This happens regardless of which Swift version is used, and it only affects functions which use Optionals. Is there a way to prevent the compiler from wrapping the API in that statement?

Prior to iOS 26.0 we were able to download specific simulator runtimes from the command line by using a command like xcodebuild -downloadPlatform iOS -buildVersion 18.0 This is described in the documentation here. This no longer works for 26.x. If I run the following command: "xcodebuild -downloadPlatform iOS -buildVersion 26.0" it fails with the following error: "Finding content... iOS 26.0 is not available for download." If I omit the -buildVersion flag it will download the latest version, currently 26.2, but if I try and specify 26.2 as the buildVersion I still get "iOS 26.2 is not available for download". This behavior has been confirmed on Xcode 26.2. Perhaps related, it appears these runtimes are also no longer being made available for download on https://developer.apple.com/download/all

So I have a project with an Objective-C framework which has unit tests. One of the unit tests has a file 'sample.emlx' in its 'Resources' folder, which has its target membership set to the tests target. I expect this file to be copied into the correct place, such that I can find it (in the 'setup') method with: NSBundle *bundle = [NSBundle bundleForClass:[self class]]; NSString *path = [bundle pathForResource:@"sample" ofType:@"emlx"]; NSData *content = [NSData dataWithContentsOfFile:path]; NSString *entire = [NSString stringWithUTF8String:content.bytes]; _sample = [entire componentsSeparatedByString:@"\n"]; NSLog(@"sample lines: %d", (int)_sample.count); The idea is to make an array where I can pull various subsections of lines out to test various parts of the code. This works every time, if I set a breakpoint at the "create the NSBundle" line, and single-step through the code after right-clicking on the specific test method I want to run It never works if I just right-click on the specific test method I want to run and allow it to run freely. I will always see "sample lines: 0" This is with the latest public Xcode, I haven't tried any beta variant.

Hi everyone, I'm experiencing a persistent issue for months now where I'm unable to download the iOS 26 simulator Runtime. I've tried reinstalling Xcode and also Xcode Beta but same issue. iOS 26 Simulator is also not on developers download page, so manual installation is impossible. And sadly I can't compile any code without having iOS 26 simulator installed. Anyone able to get passed this? Hardware: M1 Pro OS: Tahoe 26.1 Heres the error Download failed.

I have created a virtualised Mac machine where I am running the latest Xcode version 16.4 with macOS Sequoia as the base image. While running XCTest tests, I am observing a clear difference in behaviour between virtualised and non-virtualised setups. Below is the command I am using to run the tests: /Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild -xctestrun /Users/ltuser/290103613/xcui.xctestrun -destination "platform=iOS Simulator,id=79A5F8CC-4A2E-4C91-895D-AE97E25CB824,arch=arm64,OS=18.0" test-without-building "-only-testing:ClassName/MethodName/testName" -derivedDataPath /Users/ltuser/290103613/Archive -verbose IDELogLevel=debug IDETestLogLevel=debug ONLY_ACTIVE_ARCH=YES Observed Issue On virtualised hosts: Every XCTest is executed twice This happens for both passed and failed tests The behaviour is consistent across all virtualised machines On non-virtualised (bare-metal) Macs: Tests execute only once, as expected Debugging Steps Taken Multiple destination suspicion Initially, I noticed the following warning: --- xcodebuild: WARNING: Using the first of multiple matching destinations: { platform:iOS Simulator, id:0FFB9082-94AB-4D0A-A731-CC4452BDD4E7, OS:17.0, name:iPhone 15 } { platform:iOS Simulator, id:0FFB9082-94AB-4D0A-A731-CC4452BDD4E7, OS:17.0, name:iPhone 15 } This raised suspicion that tests might be running twice due to multiple matching destinations. Destination narrowed down I then explicitly restricted the destination to a single simulator UDID, after which: The warning disappeared However, the issue still persists Tests continue to run twice on virtualised hosts Version Comparison Xcode 16.4 + macOS Sequoia (virtualised) → Tests run twice Xcode 15.x (same setup otherwise) → Tests run once Questions Has anyone else faced this issue with Xcode 16.x on virtualised macOS? Is this a known issue with Xcode 16 + Virtualisation? Is there any recommended workaround or configuration change to avoid duplicate test execution? I am currently blocked on this issue and would appreciate confirmation on whether this is an Xcode or virtualisation-related problem. Thank you.

The documentation of the NSPopover property hasFullSizeContent says that when it's true, you should Use the safeAreaLayoutGuide of the contentViewController view to ensure that your content is fully visible and doesn’t become clipped when displayed. I can do that by adding auto-layout constraints programmatically, but is there a way to do it in the xib? When I googled it, the AI summary begins To use safe areas in a Mac XIB (Interface Builder), enable the "Use Safe Area Layout Guides" checkbox in the File Inspector for your view but I have not found any non-AI indications that such a checkbox exists for macOS. (I'm using Xcode 26.2.)

hy! apple developer community! No, I have a problem that's driving me crazy: Multiple commands produce '/Users/giulia/Library/Developer/Xcode/DerivedData/ScheduledStudy-dcmmhcdncitvfkdditbjoipfalqg/Build/Products/Debug-iphonesimulator/singintestwidgetExtension.appex/Info.plist'. Can you help me fix it? I know it's probably stupid, but I've been trying to fix it for days. There aren't two info.plist file, and that's why I don't quite understand. If you could help me, you'd be doing me a favor. Thanks for your time. P.S. I'm sorry, but I'm just starting out with programming and I'm also quite young.

I’m using macOS Tahoe 26, and Xcode is version 26.2. I’ve tried all the methods suggested online, but I still can’t download it. In addition, iOS 26.* and iOS 18.* simulators also fail to download.

Each time I try to launch Xcode 26, it immediately crashes in SourceEditorDataSource.ideChat_gracefullyApplyChangesToReflect. I'm now no longer able to use Xcode. A partial crash log attached. So far I've tried deleting derived data, rebooting, deleting ~/Library/Caches/com.apple.dt.Xcode. What should I do? Thank you in advance for any help. crash-report.txt

I'm having a strange issue with my iOS app icon rendering in the App Store - it seems to be low-res and clipping part of the image. I updated the icon in Icon Composer to apply the liquid glass overlay for the new build. It looks fine on the device and the asset itself isn't corrupted. I think it might be a resolution issue since the small icon thumbnails in App Store Connect have the same problem, but they look fine when I click through to the larger preview. Has anyone else run into this and figured out a fix?

I've been going through different fixes for a few weeks and nothing seems to work. Prior to updating everything to iOS 26 and OS 26, everything worked normally except for the predictive code which wouldn't download. Download failed.

Trying to develop a little Watch app in Swift, and it's been kind of a miserable experience. I constantly get transport errors trying to connect to my watch. I've tried the trick of putting the Mac and the watch on my iPhone hotspot instead of just on the same WiFi network, but I am not sure that actually helps. I can run maybe once or twice, and then the transport error happens and it's very hard to get XCode to recognize the watch again. Also, when it DOES connect, it seems that XCode almost always loses the debugging connection (I just continue, and it IS actually running on the Watch at that point, but no debugger).

I'm trying to manage multiple Command Line Tools versions side-by-side (e.g., 16.2 and 26.2). I renamed the CLT directory to /Library/Developer/CommandLineTools-26.2.0 and set: xcode-select -s /Library/Developer/CommandLineTools-26.2.0 or DEVELOPER_DIR=/Library/Developer/CommandLineTools-26.2.0 Both result in: c++: error: unable to find Xcode installation from active developer path "/Library/Developer/CommandLineTools-26.2.0" It appears CLT only works at the fixed path /Library/Developer/CommandLineTools, unlike Xcode which can be at any location. Is this by design? Is there a supported way to use multiple CLT versions in parallel, similar to how multiple Xcode versions can coexist?

I'm trying to download an iOS Simulator runtime in Xcode 26.2 or 26.1 on macOS 26.1, but the download keeps failing with the following error: Download failed. Domain: DVTDownloadableErrorDomain Code: 41 Failed fetching catalog for assetType (com.apple.MobileAsset.iOSSimulatorRuntime), serverParameters ({ RequestedBuild = 23C54;}) Domain: DVTDownloadsUtilitiesErrorDomain.

Completely deleted Xcode and its related files several times (/Applications/Xcode.app, caches, preferences). Tried different internet connections from multiple locations. Checked Apple servers and verified network. Attempted downloading other simulator runtimes (fail). but download fails immediately with DVTDownloadableErrorDomain Code 41 and bad URL error. Question: How can I fix the simulator download issue in Xcode 26.2 on macOS 26.1? Is there a known workaround for the bad URL / catalog download error?

I set "show live issues", but in the Xcode 26.2 version, I defined an unused variable in the function. This variable does not trigger real-time warnings; it only alerts when the compilation is completed. What settings should I make to trigger an alert for unused variables in real time?

Hi, I am running build on ios 26.2 device, connected with cable (not wifi) and it crashes because files are not loaded or something. But when i turn off Debug Exetuble, it works just fine. Also, tried to run on ios 18.2 device, with Debug executable On - everything is ok, and breakpoints work. My guess, App crashes on reading and loading Assets and others app files like certificates. XCode run logs shows: **"Too many file errors". ** sample.txt xcode_run_logs.txt Also, exectued image list on lldb console, could not attach here, if needed i can add it with some url here.
