I’m working on an iOS workspace with: a static library project: M800SDK a test app project: TestAppObj I was able to build M800SDK for iOS Simulator on Apple Silicon as a simulator static library, and I also verified the architectures in the produced .a file. However, when I link the app target against that simulator build and try to build TestAppObj for iOS Simulator, I get the following linker errors: Undefined symbols for architecture arm64: _OBJC_CLASS_$_TokenMngr clang++: error: linker command failed with exit code 1 Additional context: The library links and works correctly when building the app for a physical iPhone. And the public header TokenMngr.h is found correctly by the app target. The app target is compiled as Objective-C++ where needed. The library is linked in the app target under “Link Binary With Libraries”. Could you help me understand: Is it possible to run on iOS Simulator ? the recommended way to package and consume this library for iOS Simulator on Apple Silicon? Also I am aware i can also build the library for : Any iOS Simulator Device (arm64, x86_64) And specify that on Build Phases in Link : Link Binary With Libraries adding the .a Before i do that i ensure the .a is arm64, x86_64 using the command : lipo -info libM800SDK.a end it returns : Architectures in the fat file: libM800SDK.a are: x86_64 arm64 However, even after confirming those architectures and linking the library to the app target, the app still does not link correctly for iOS Simulator. In some cases, Xcode reports errors suggesting that the build is targeting iOS Simulator, but that one of the linked binaries was built for iPhoneOS instead. This is where I am confused: I understand that lipo -info only shows the CPU architectures present in the library, but not whether a given arm64 slice was built for iPhoneOS or for iOS Simulator

I'm trying to use Xcode 26.3's official MCP Server (xcrun mcpbridge) on an Intel Mac（15.7.4）, but it crashes immediately. Run xcrun mcpbridge in Terminal： dyld[3809]: Symbol not found: _$s10AppSandbox17ASBBinaryIdentityC14teamIdentifierSSSgvg Referenced from: /Applications/Xcode.app/Contents/Developer/usr/bin/mcpbridge Expected in: /System/Library/PrivateFrameworks/AppSandbox.framework/Versions/A/AppSandbox [1] 3809 abort xcrun mcpbridge Observations The same command works on an Apple Silicon Mac (M1, macOS 26.3).

Area: Software Update Type of Feedback: Application Bug Description Device: iPhone 13 Pro running iOS 26 Build environment: Xcode 16.4 Problem description: When a text field has secureTextEntry = YES and Password Autofill / Passkeys is active, the autofill panel is not included in the rect reported from the keyboard notifications (UIKeyboardFrameEndUserInfoKey or others). As a result, when calculating the offset to move the screen up and reveal the hidden input field, the field is not displayed correctly because the reported keyboard height is smaller than the actual visible height. Observed behavior: This only occurs on devices running iOS 26 built with Xcode 16.4. On previous versions of iOS, with the same settings (secureTextEntry and Autofill active), the rect correctly includes the autofill panel height, and the UI works as expected. I tested with both UIKeyboardDidShowNotification and UIKeyboardWillChangeFrameNotification, and in both cases the behavior is the same: the height is incorrect (smaller than expected with the autofill panel). What I expect / questions: That UIKeyboardFrameEndUserInfoKey (or the related notification) correctly reports the total area covered by the keyboard, including any password autofill panel, when secureTextEntry is active. That the new behavior in iOS 26 be documented if this omission is intentional, or otherwise considered a bug if it is not. If there is any official workaround suggested by Apple for developers affected by this issue while a fix is provided. Thank you for your support.

I have three rogue iOS simulators, how to correctly delete them and reclaim the disk space? These img files are costing me 18gb of storage.

I would like to have the option to keep my xcode project open regardless of closing all tabs using cmd + w.

Xcode 16 and 26 changes in painful way how the Tab key works during autocomplete. Previously, pressing Tab would extend the typed text up to the word match. For example, we have two classes: NSViewController and NSViewCoordinator BEFORE, typing: "NSV" + Tab used to complete to NSViewCo Now, in Xcode 26, pressing Tab just use the first suggestion. Stupidly. Especially when you want DispatchQueue and it gaves you DispatchSemaphore… That is very inconvenient because very often I want just see all possible cases with some prefix...without need of typing all prefix manually. How to restore the previous behavior? How to do autocomplete word-by-word?

Hi, I am working on app at the moment that uses Icon Composer for all of its icons and variations. I want to add an iMessage App to my project however I get validation errors from App Store Connect even if I add an imessage app to my asset catalog and include all app icon assets. Is there any way to do this at the moment natively with Icon Composer? If not how do I manually overwrite the icon JUST for iMessage and not for my entire iOS app?

I'm facing an issue with Swift Playgrounds and files created in Xcode 16. It seems that Swift Playgrounds does not support Swift 6, but even when I create files specifically with Swift 5, Swift Playgrounds still reports that the files are unsupported. This creates a significant problem because macOS Sequoia does not allow me to revert to Xcode 15, which might have offered better compatibility. As it stands, I can't find a solution to work seamlessly between Xcode and Swift Playgrounds. Has anyone else encountered this issue? Are there any workarounds or updates planned to address this compatibility gap? Any advice would be greatly appreciated!

Can I download the iOS 26 simulator runtime via a download link? The machine I need to deploy on may require an offline package installation due to firewall restrictions.

Hello, I was told from Developer engineers to post an Xcode issue on Feedback Assistant. It has been 6 weeks and I have yet to receive a single reply or acknowledgement on my feedback post. I would just like to at least get some sort of acknowledgement from Feedback Assistant that my post is being tracked or if a resolution is in work please. Here's the post: https://feedbackassistant.apple.com/feedback/21824703

In the Coding Intelligence feature introduced in Xcode 26, when I send a message using ChatGPT in Xcode, the message “Your request couldn't be completed. Networking error.” appears and I’m unable to use the feature. I suspect the issue may be related to the VPN or network proxy connected to my Mac and am attempting to investigate. However, Xcode does not display any specific error details, nor does it provide a way to view them, which makes a detailed investigation difficult. Next to the error message, there is a feedback button rather than a stethoscope (🩺) button, and the feedback window does not provide access to the underlying error information. Is there a way to view the detailed network error logs generated by ChatGPT in Xcode? (I am using Xcode 26.0.1.)

Hi everyone, I’m running out of space on my Mac and I need to use an external SSD to free up room, especially because Xcode is taking a lot of storage. I want to know if it’s safe to move some Xcode files—projects, derived data, or system-related files—to an external SSD. Which files can I move safely, and which should stay on the internal drive? I want to avoid breaking anything or causing issues with Xcode or macOS. Also, is it the same situation if I use an external HDD instead of an SSD? Are there additional risks or performance issues to consider?

I'm struggling to build a driver for iPadOS in a particular project configuration. If I put the driver code and dext target into the same Xcode project which contains the iPad app, all is well. This is the way the Xcode driver template does it. However, I'd like to build and debug the dext on macOS, while eventually deploying on iPadOS. So I put the dext into a different project, which has a macOS target, a minimal iPadOS target and a DriverKit target. I made a workspace which contains both projects. I dragged the macOS project into the iPadOS project so that I can refer to the products of the macOS project (specifically, its driver target) as a dependency of the iPadOS target. Note that the main iPad app target depends on the driver target. So the workspace organization looks like this: Workspace iPad project main iPad app target (depends on driver) test project reference test project test macOS/iPad app target DriverKit dext target When I build the iPadOS target, it builds the dependent driver target in the macOS project, but it fails to link because Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang/15.0.0/lib/darwin/libclang_rt.profile_driverkit.a is not found. If I just build the driver target directly in Xcode, there is no such complaint. I looked closely at the build logs, and I see for the failed link, there are these two linker flags set which are not set in the successful case -debug_variant -fprofile-instr-generate I can't seem to control the generation of this flag. I tried turning off the Profile switch in the Scheme editor for the driver, but is makes no difference. When I directly build the driver target, no -fprofile-instr-generate is set and it compiles and links. When i build the driver as a dependency of another target, -fprofile-instr-generate is passed to the linker, which fails. The obvious workaround is to put the driver source code into a separate driver target in the iPadOS project, but I'd rather have just one DriverKit driver for both platforms, with a few settings (such as bundle ID) controlled by a configuration file. Has anyone else encountered this problem, and know of a workaround?

On XCode 26.x, calling XCFail with continueAfterFailure set to false causes xcodebuild command to hang indefinitely if the XCUIApplication object is stored outside the test method. Create a new template iOS App project with UI tests Add XCFail(...) to a UI test test-case Set the XCUIApplication in self.app (avoiding this fixes the hang) Run tests with xcodebuild test The terminal hangs forever Reproduction example import XCTest final class TestAppUITests: XCTestCase { var app: XCUIApplication? = nil override func setUpWithError() throws { continueAfterFailure = false } override func tearDownWithError() throws { app?.terminate() } @MainActor func testExample() throws { let app = XCUIApplication() self.app = app // <- HERE this causes the problem app.launch() XCTFail() } } Reproduction environment macOS Sequoia 15.7.3 Tested XCode 26.3 and XCode 26.2 have the hang Tested XCode 16.4 does work as expected XCode 16.4 The issue does not happen on XCode 16.4, and is likely introduced in XCode 26. Related threads: https://developer.apple.com/forums/thread/809989 https://developer.apple.com/forums/thread/793307 Work-around Do not store XCUIApplication in the XCTestCase instance, maintain it scoped to the test methods.

I have Xcode 26.1.1 (installed on a Mac Mini with Sequoia 15.7.2), which was installed from the Universal .xip file available from the Apple Developer site. This file is 2.7Gb. When Xcode is run, there is a menu item at Settings -> Components, and the top section "Platform Support" includes an option to "Get" the iOS SDK, which is an additional 10.3Gb download.[1][2] I would like to either use command-line tools to obtain this iOS SDK component, or find where the downloaded package or its contents are installed on this Mac. This Apple Documentation some examples of using command-line tools to download components for Xcode. However, there is no specific documentation on how to separately download the iOS SDK. It seems that if possible, it could be done with "xcodebuild -downloadComponent", however I have tried a number of likely component names (ios, ios_sdk, ios26.1, ios_sdk26.1, iphoneos, iphoneos_sdk, iphoneos_sdk26.1), and none are valid. Does anyone know either where the SDK download can be found, or how to download it using command-line tools? Background: I require this as I am managing a fleet of Mac Minis located in a data centre (used for iOS/Android builds), and Internet access is restricted - any action requiring Internet access needs the Mac to be removed from the machine room racks and taken to a build room, then connected to a mobile hotspot or similar. This access is slow, and the above 10.3Gb download can take over an hour. If I can download the SDK separately, I can distribute it to all of the Macs over the internal network overnight, in advance of visiting the DC for upgrade tasks. [1] Various web sites say that the iOS SDK is "bundled with" Xcode. However, if that's the case a) how is a 10.3Gb download somehow included in a 2.7Gb file? And b) why do I still need to "Get" this component after installing Xcode from the 2.7Gb file? [2] Note that I am not looking for the iOS Simulator, I have already downloaded the iOS 26.1 version of this. I am specifically looking for the iOS SDK as listed under "Platform Support" in the Xcode menu described above.

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
