Will Icon Composer support development of tvOS and visionOS icons?
In the beta of Icon Composer, I see macOS, iOS, and watchOS icons, but there is nothing about visionOS and tvOS. Those icons are particularly hard and it would be great if this app worked for developing icons for all Apple platforms. I tried asking this in a WWDC group lab, but they didn't get to it and suggested posting to the forum.

How to report Xcode 26 / iOS 26 bugs with Feedback Assistant?
I'm running macOS 15.5. I now have Xcode 26 and I'm testing my iOS app against iOS 26. I've encountered several UIKit / iOS 26 bugs I'd like to report. In Feedback Assistant I choose "Developer Technologies & SDKs". Eventually I get asked "What build does the issue occur on?". The list of choices is: iOS 18.2 Seed 4 iOS 18.1.1 iOS 17.7.2 An earlier iOS build I'm not sure So how to I report this as an iOS 26 beta 1 issue?

The Xcode project keeps crashing on launch
Hello, I need a little bit of help. My game keeps crashing on launch no matter what I do. I’ve tried running it in Xcode on my Mac, on my iPhone, and through TestFlight, but I get the same result every time. I’ve tried everything I could find on the internet, and nothing worked. Asking here is my last resort because I’m completely stuck. The game runs fine in Unity, but not so much in Xcode. Can someone help me figure out what I’m doing wrong?Any help would be greatly appreciated. Here is the error log I found by connecting my iPhone to my Mac. To view the logs, I used the Console in the Devices and Simulators section of Xcode. ➤ SecKeyVerifySignature failed: Error Domain=NSOSStatusErrorDomain Code=-50 "rsa_pub_crypt failed" [10:27:36.034791+0200] kernel ➤ Sandbox: [App] deny(1) sysctl-read kern.bootargs [10:27:36.043389+0200] SpringBoard ➤ Live host view super view[(null)] not matching container view ➤ Frame not updated [10:27:36.050473+0200] backboardd ➤ Cycle detected [10:27:36.100799+0200] SpringBoard ➤ Live host view super view[(null)] not matching container view [10:27:36.538361+0200] akd ➤ Error fetching keychain item - Error Domain=NSOSStatusErrorDomain Code=-25300 "no matching items found" [10:27:36.545734+0200] akd ➤ Failed to set last known MID with error (Error Domain=NSOSStatusErrorDomain Code=-25300) [10:27:36.603384+0200] rtcreportingd ➤ Gap in hierarchy: [10:27:36.604536+0200] cloudd ➤ TCP input flags=[R.] state=LAST_ACK [10:27:36.613317+0200] cloudd ➤ TCP input flags=[R] state=CLOSED [10:27:36.648449+0200] kernel ➤ 1 duplicate report for Sandbox: [App] deny(1) sysctl-read kern.bootargs [10:27:36.648484+0200] kernel ➤ Sandbox: [App] deny(1) file-test-existence /private/var/Managed Preferences/mobile/com.apple.CoreMotion.plist [10:27:36.900275+0200] CommCenter ➤ Client is not entitled for request [10:27:37.131555+0200] storekitd ➤ AMSURLSession: Session decoder failed.

Problem getting Expectation objects (AI slop)
This is from an Xcode generated file. var values: [String] = [] let exp = Expectation() let c = pub.filter { $0 != nil }.map { $0! }.sink( The second line gives an error: "'Expectation' cannot be constructed because it has no accessible initializers". My best guess that Expectation objects come from some other Apple Swift Testing function, but I don't know where.

Immediate crash of Apple Watch simulator when typing a key
I get a crash in Apple Watch simulator (Series 9 45mm 18.0) as soon as the app launch if I type anything on external keyboard (just hitting command key for instance to capture a screenshot). Same crash on series 7 (45mm, OS 18.1) But app works normally when I use mouse to interact with the app on simulator. App does not crash on real device (Watch 4 OS 10.4.1). Nor does it crash on Series 6 simulator (44 mm OS 17.4). Here are the log I could collect (apparently, they contain sensitive language !!! so I attach as a file.: Attached logs

Unstable behavior of xcodebuild -showdestinations
Hi, I am having an issue with xcodebuild -showdestinations command. Steps to reproduce: Create a new iOS application project in Xcode or use an existing one. Navigate to this project in a terminal. Run xcodebuild -project 'your-project-name.xcodeproj' -scheme 'your-scheme' -showdestinations What I expect: All destinations available in the Xcode UI should be listed. What I get: It depends. For new projects, I consistently get only generic platform destinations and my connected physical device. When I run the same command on an older project, I sometimes see all the expected destinations. It seems to be a roughly 50/50 chance between the two outcomes. Is there a way to get consistent results from xcodebuild -showdestinations? What can I do to ensure all destinations are listed reliably? Here is a more detailed log and a screenshot: ❯ xcodebuild -workspace 'WorkoutDiary.xcworkspace' -scheme 'WorkoutDiary' -showdestinations Command line invocation: /Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild -workspace WorkoutDiary.xcworkspace -scheme WorkoutDiary -showdestinations User defaults from command line: IDEPackageSupportUseBuiltinSCM = YES 2025-06-17 19:13:50.261 xcodebuild[34753:6177985] DVTDeviceOperation: Encountered a build number "" that is incompatible with DVTBuildVersion. 2025-06-17 19:13:50.342 xcodebuild[34753:6177959] [MT] DVTDeviceOperation: Encountered a build number "" that is incompatible with DVTBuildVersion.

How to package a static library and headers into an XCFramework?
I have static libraries and headers of a C++ project that I believe are correctly built for iOS and iOS Simulator destinations. The C++ project is built via CMake with something like: cmake dirName \ -G "Unix Makefiles" \ -B buildDir \ -DCMAKE_INSTALL_PREFIX=installDir \ -DCMAKE_SYSTEM_NAME=iOS \ -DCMAKE_SYSTEM_PROCESSOR=arm64 \ -DCMAKE_OSX_ARCHITECTURES=arm64 \ -DCMAKE_OSX_SYSROOT=$(xcrun --sdk iphonesimulator --show-sdk-path) \ -DCMAKE_OSX_DEPLOYMENT_TARGET=15.0 ... cmake --build buildDir --config Release --target install I believe those are all the important parameters. This gives me a static library (.a) and headers that I believe should be compatible with arm64 iOS simulators, and I do this same thing for x86_64 architecture with simulators and for actual iOS non-simulator via the iphoneos SDK path. I'm pretty sure this gives me the correct static lib and headers. Let's assume it does because I'm not able actually create the XCFramework to know if they're right. This does work with a macOS lib and headers, but I need iOS for this library. How do I package this into an XCFramework now? This Apple developer articles says I should be a able to create an xcframework via xcodebuild -create-xcframework -library libName.a -headers include but when I try to do this with my my iOS arm64 simulator static lib I get: error: binaries with multiple platforms are not supported '/Users/.../install/ios-arm64-simulator/libName.a But, when I run: lips -info libName.a I get Non-fat file libName.a is architecture arm64, so, I'm not sure what to do here. Trying to extract arm64 from that static library also produces an error as it it is just an arm64 lib. I'm not really sure what's going on, but from reading online this specific command, xcodebuild -create-xcframework is a consistent pain point in the process of trying to get an XCFramework, and the seemingly only workaround is to archive a framework project and then create the xcframework via xcodebuild -create-xcframework -archive MyFramework.xcarchive -framework[or -library]. However, how am I supposed to get this static lib and headers into a suitable xcodeproj so that I can archive it correctly? Everytime I try to copy the headers and static lib into the Framework xcodeproj and set what I believe are all the correct settings, my .xcarchive is always empty. Does anyone have any advice here on how to get this to work? The main impetus for trying to get this C++ static lib and headers into an XCFramework as that seems like the only valid way to link a 3rd party C++ lib to an SPM package and have the C++ package be interfaceable with Swift.

Static library produced by Xcode 26 causes link error on Xcode 16
When a static library is built with Xcode 26 (with deployment target set to iOS 13) and then linked into an app project compiled with Xcode 16, the build process fails with the following linker error: Undefined symbols for architecture arm64: "_swift_coroFrameAlloc" This occurs even though both the static library and the app project have their deployment targets set to iOS 13.0. The static library works on Xcode 26, but fails to link on Xcode 16. This issue shows up with certain Swift syntax. For example, in my case, using a property getter and setter caused the compiler to emit a reference to _swift_coroFrameAlloc, which in turn triggered the issue. This issue prevents us from distributing pre-built static libraries compiled with Xcode 26 to teammates who are still using Xcode 16. I’ve filed feedback for this issue (FB21130604). Is there any way to work around it? For example, by adding specific Build Settings or something similar? A demo project is available here: https://github.com/Naituw/SwiftLibraryDeploymentTargetIssue The demo project includes: StaticLibraryProject: A simple Swift static library with property getter setter usage AppProject: An iOS app that links against the static library verify_compatibility.sh: An automated script to reproduce the issue Method 1: Manual Build and Verification Open StaticLibraryProject/StaticLibraryProject.xcodeproj in Xcode 26 Build the StaticLibraryProject for iOS device (Release configuration) Locate the built libStaticLibraryProject.a in the build products directory Copy libStaticLibraryProject.a to AppProject/AppProject/ directory Open AppProject/AppProject.xcodeproj in Xcode 16 Build the AppProject for iOS device Method 2: Automated Script Edit verify_compatibility.sh to configure the paths to your Xcode installations: Set XCODE_26_PATH to your Xcode 26 installation path (e.g., /Applications/Xcode.app) Set XCODE_16_PATH to your Xcode 16 installation path (e.g., /Applications/Xcode16.app) Run the script: ./verify_compatibility.sh

NSUserDefaults + iPhone Transfer Issues
Hi! I was wondering if anyone else encountered similar issues and what the solution ended up being. We're encountering weird sign-in issues on our iOS version of our app. It seems like an uninstall and reinstall solves it, but the issue seems to only impact users who underwent the transfer process from one iOS device to another. What I am curious about: What is copied over from one device to another in this process? Is there a way outside of owning multiple test devices to replicate this flow? Our current suspicion is that NSUserDefaults is not being cleared by our app on first start, and that stale data is copied over during this transfer process, breaking the sign-in until a re-install wipes everything properly. Does it seem like we're on the right track with this assumption, or completely out to lunch?

libclang_rt.profile_driverkit.a' not found
Hi guys! I have gone through an absolute nightmare, trying to solve the issue that I am about to tell you about. As the title says, I am getting the error: Library '/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang/17/lib/darwin/libclang_rt.profile_driverkit.a' not found I trimmed off part of that directory as I did not want to reveal that information about my computer. From what I can tell, the file in question is no longer even a part of Xcode. I have searched, it is not on my computer anywhere. I have also downloaded older versions of Xcode to search with it. None of them have it. I have literally tried everything under the Son to solve this issue. I have been stuck on it for two days. I have even resorted to doing something I hate, which is asking for ChatGPT to assist me with solving the issue. No help there. I am at my wits end. So I am coming to you guys, have you seen this error? Any ideas at all? The odds are pretty good whatever you recommend I have probably already tried 200 times over. But I am still open to hearing anything. Have any of you had this error? Any ideas? I am on the latest version of macOS. The project is for a macOS app. M4 Mac mini. Any additional information I can provide, that will be helpful? At this point, I am leaning more towards this being a bug with Xcode than anything.

Why does a Swift test think my simple struct is main actor-isolated?
My experience with Swift 6 strict concurrency so far doesn't match my understanding of implicit MainActor isolation semantics. This is a cross-post from StackOverflow. I will link answers between both forums. TL;DR Build succeeds when testing a struct declared in the test module, but fails when the struct is moved to the main module: Main actor-isolated property … cannot be accessed from outside the actor. Steps to reproduce Open up Xcode 26 beta 2 on macOS 26 (probably also ok on current stables). Create a new Swift app with Swift testing, no storage. Call it WhatTheSwift. Set the Swift Language Version on all three targets to Swift 6. Update the default test file to be this: import Testing @testable import WhatTheSwift struct WhatTheSwiftTests { @Test func example() async throws { let thing = Thing(foo: "bar") #expect(thing.foo == "bar") } } struct Thing { let foo: String } That should build fine, and the tests should pass. Now, move the Thing declaration into its own Thing.swift file in the WhatTheSwift module, and try running the test again. You should see this: Observations Marking the test @MainActor allows the test to pass, suggesting the compiler actually wants to isolate Thing.foo to the main actor. My question Why? And why only when Thing is in a different module?

Unable to Test Xamarin App with iOS 26 Simulators in Visual Studio
Hello, I’m trying to test a Xamarin.iOS application using the iOS 26 simulators in Mac Visual Studio, but I’m encountering an issue where the simulators are not appearing or accessible from Visual Studio. Details: macOS version: 15.6 (24G84) Xcode version: 26 Beta 5 Visual Studio version: 17.6.0.80 Xamarin.iOS version: Xamarin.Forms (Version: 4.6.0.1180) using XAML for cross-platform support (iOS/Android) The problem started after updating to iOS 26 SDK. I am unable to select or run the app on any iOS 26 simulator from Visual Studio. Has anyone faced a similar issue? Is there any configuration or workaround to enable iOS 26 simulators for Xamarin projects? Thanks in advance for your help.

Is the new iPadOS/macOS 26 help icon available in SF Symbols?
Under macOS 26 and iPadOS, the Help menu in many cases has a menu item for "App Help". This item has the following icon: I need to use this in my own app. I am unable to find this icon in SF Symbols 7 beta. I've scanned all of the icons under "What's New". I've searched for "help", "light", and "bulb" and this icon does not appear. Does anyone know if it's even a new SF Symbol? Or does anyone know of a way to use this icon?

How to install cocoapods and pod
Hi, I am developing IOS(Android App) with React Native. I am very confused about cocoapods and pod and how to correctly install it on my new Macbook Pro M4. I am not using bash but I am using zsh. Note, actuallywhich pod return nothing During the preparation of my environment, it say CocoaPods is one of the dependency management system available for iOS. CocoaPods is a Ruby gem. You can install CocoaPods using the version of Ruby that ships with the latest version of macOS. the web site show two commands gem install cocoapods sudo gem install cocoapods I saw another command as well brew install cocoapods During different processes, I experienced several time the following error (Command 'pod install failed) Command pod install failed. └─ Cause: pod install --repo-update --ansi exited with non-zero code: 1 Then I am confused about cocoapods and pod. Are both he same? With my previous MacBook pro, I spend time to install cocoapod on my profile because Ruby was not the latest version on the system. But apparently, on my new Macbook Pro M4, the command ruby -v return (as well) ruby 2.6.10p210 (2022-04-12 revision 67958) [universal.arm64e-darwin25] The current stable version is 4.0.0. I bought a new macbook pro M4 and I reinstalled node and all package for Rect Native 0.81 a expo 54 excepted cocoapods. Now, I need to configure the push notification and it's time to install cocoapods as it's require here But on my new macbook pro, I would like to make sure I do it correctly and I kindly ask your help and recommandation to install Ruby and cocoapods/pod Q1: Should I install cocoapods with brew install cocoapods or gem install cocoapods? Q2: what's is the difference or the common point with cocoapods and pod? Cocoapod web site said If using the default Ruby included with macOS, installation will require you to use sudo when installing gems As ruby -v print 'ruby 2.6.10p210', I suppose, I should not install cocoapod with sudo You can use a Ruby Version manager such as RVM or rbenv to manage multiple Ruby versions, or you can use Homebrew to install a newer Ruby with brew install ruby. As far I understand, I should not install cocoapods with the Ruby version of the system, then I suppose the command Q3: Will 'brew install cocopads' install the latest version on my profile? Will it upgrade the system version Q4: What will do the command brew install rbenv ruby-build rbenv install 3.2.2 (or better: rbenv install 4.0.0) in comparison with brew install ruby My guess I suppose that the following will help, but it would nice if you could correct me and clarify # All should be done in my profile brew install rbenv ruby-build echo 'eval "$(rbenv init - bash)"' >> ~/.zprofile source ~/.zprofile rbenv install 4.0.0 # rbenv global 4.0.0 # What is it? ruby -v gem install cocoapods Q5: But then, what about pod and the error message Command pod install failed. As you can see, I am a bit confused and I would appreciate your clarification I thanks you for your help and clarification and I wish you a happy new years
