Xcode 26.6 no longer shows the built-in Agents (Codex / Claude Agent) in Intelligence settings
Installed from the Mac App Store Signed in with my Apple ID in Xcode Apple Intelligence is enabled Chat providers work normally (ChatGPT, Claude, Google) What I expected According to Apple's documentation, the Intelligence settings should display built-in Agents such as: Claude Agent Codex with a Get button to install them. Reference: https://developer.apple.com/documentation/xcode/setting-up-coding-intelligence What actually happens After upgrading to Xcode 26.6, the Agents section only contains: Allow external agents to use Xcode tools Add an Agent... The built-in Agents (Claude Agent and Codex) are completely missing.

Xcode 26.6 (17F113) -Onone: UIScene.ActivationState enum comparison crashes at runtime (works in Release)
Summary On Xcode 26.6 (17F113) / Swift 6.2, a Debug build (-Onone) crashes at runtime when comparing UIScene.ActivationState inside a closure passed to Array.first(where:). The exact same code runs fine when built with optimizations (-O / Release). This looks like an -Onone code-generation (miscompile) bug rather than a logic error in the app. Environment Xcode: 26.6 (17F113) Toolchain: Swift 6.2 (Apple default toolchain) Optimization: SWIFT_OPTIMIZATION_LEVEL = -Onone (Debug scheme) Deployment target: [ iOS xx.x ] Run destination: [ Device / Simulator — model, OS version ] Configuration: also reproduces in a fresh checkout after Clean Build Folder + DerivedData wipe Steps to Reproduce Add the following to any app and call it early in the launch path (e.g. from an async context / Task during startup): import UIKit enum ScreenUtil { static var keyScene: UIWindowScene? { let scenes = UIApplication.shared.connectedScenes .compactMap { $0 as? UIWindowScene } // Crashes here in Debug (-Onone) on Xcode 26.6 (17F113) return scenes.first { $0.activationState == .foregroundActive } ?? scenes.first } } 2. Build and run with the Debug scheme (-Onone). 3. The app crashes as soon as keyScene is evaluated. Expected keyScene returns the foreground-active UIWindowScene (or the first scene), identically to the optimized build. Actual Immediate crash when the closure evaluates $0.activationState == .foregroundActive. UIScene.ActivationState is an Objective-C-imported (NSInteger-backed) enum, and the failure appears tied to how its value is handled under -Onone. The crash surfaces inside Swift concurrency resume plumbing because keyScene is reached from an async context at launch. Representative frame: (1) await resume partial function for partial apply forwarder for reabstraction thunk helper ... @isolated(any) @callee_guaranteed @async () -> (@out τ_0_0) ... -> ldr x0, [x22, #0x8] ; faults here br x0 ; preceding: bl swift_task_dealloc Reproducibility - Debug (-Onone): crashes 100% - Release (-O): works correctly Workaround Rewriting the closure comparison as an explicit loop avoids the crash: static var keyScene: UIWindowScene? { let scenes = UIApplication.shared.connectedScenes .compactMap { $0 as? UIWindowScene } for scene in scenes where scene.activationState == .foregroundActive { return scene } return scenes.first } Notes A sysdiagnose / crash log and a minimal sample project are attached via Feedback Assistant (FB[ number ]). Happy to provide additional details.

Device Hub sucks
Or maybe I suck? Is there really no way with the new Xcode to take a simple screenshot from the device you're testing?You have to connect this Device Hub? An entirely separate app. And not only that, then you have to pair it, which maintains a live connection to the phone? Fine. Okay then. But now I can no longer test the microphone functions of my app because that shared session is interfering with it. Oh, well, I'll just disconnect the session then, right? Nope. The button to disconnect the session doesn't work. Device Hub thinks it's disconnected, but my phone still shows the blue sharing session icon in the upper left hand corner. The only way to stop that is to unpair the phone completely. So then every time I want to take a screenshot, I've got to do this pairing crap? I think I'll be running a second copy of Xcode 26 for quite a while just to use the screenshot button.

Apple watch series 9 (OS 10.3) not showing up in xcode 15.1 under devices list.
When connecting my iphone (14pro with iOS 17.2.1) with a paired apple watch (series 9 with OS 10.3), it is not showing up on the devices/simulators list in xcode 15.1. Beyond unpairing/repairing the watch, restarting either iphone or watch, connecting/disconnecting the iphone from the computer or deleting xcode and re-installing xcode, any other suggestions? Under the WatchApp field it shows "no eligible device connected", however, under the console the Apple Watch does appear. I have tried just about everything and can't get the watch to appear in Xcode. I am running all this on a MacBook Pro with Sonoma. Thanks for any assistance!

Xcode won't sign into ChatGPT Codex account anymore
As of May 8th, 2026, after I upgraded to "codex-cli 0.129.0" via Xcode, I can no longer sign into my ChatGPT account in Xcode Intelligence Settings. The Log In window is always successful, but the settings never update to show the login being successful. It's a constant loop. Perhaps a hand-shake fail. Versions: Tahoe 26.3.1, Xcode 26.4.1, codex-cli 0.129.0.

Xcode Codex sign-in fails after updating OpenAI component
Environment: macOS: Tahoe 26.4 Xcode: 26.5 ChatGPT account successfully authenticated Codex CLI installed and working Codex App installed and working Steps to reproduce: Install Xcode Codex/OpenAI component version where GPT-5.4 is the highest available model. Sign in with ChatGPT account. Confirm Codex works in Xcode. Update the OpenAI/Codex component in Xcode. Attempt to sign in again. Expected result: Xcode completes authentication and shows signed-in status. Actual result: Browser successfully completes authentication and displays "Signed in to Codex." Xcode remains in a sign-in loop or shows "Not Signed In." Authentication never completes. Additional observations: Codex CLI authentication succeeds. Codex App authentication succeeds. ChatGPT web/app access succeeds. Anthropic/Claude component updates continue to work normally in Xcode. Issue appears specific to the updated OpenAI/Codex Xcode component. Older component (GPT-5.4 maximum model available) authenticates successfully.

Reproduction Minimal, reproducible with the plain command-line tool — no Claude tooling involved in this step: SHELL xcrun simctl install "iPhone 17 Pro" "/DerivedData/Build/Products/Debug-iphonesimulator/QuestionsWeCarry.app" Result (100% reproducible, every attempt): STDERR An error was encountered processing the command (domain=IXErrorDomain, code=13): Simulator device failed to install the application. Missing bundle ID. Underlying error (domain=IXErrorDomain, code=13): Failed to get bundle ID from /QuestionsWeCarry.app Missing bundle ID. Also reproduced with xcrun simctl launch, which fails as a consequence: Isolation steps taken All of the following were tried, and none changed the outcome — the exact same "Missing bundle ID" error occurs every time: 01 Two signing configurations — unsigned/linker-signed (Sealed Resources=none) vs. proper ad-hoc sign (Sealed Resources version=2 rules=13 files=4), plus a manual codesign --force --deep --sign - re-sign pass. Same failure every time. 02 Two simulator destinations — generic/platform=iOS Simulator and a concrete device id for iPhone 17 Pro. 03 Two never-before-used simulator devices — iPhone 17 Pro and iPhone Air — ruling out per-device CoreSimulator state corruption. 04 Erase + cold boot — simctl shutdown, erase, boot immediately before a fresh install attempt. 05 Real Simulator.app GUI running — not just a headless simctl boot — ruled out a CoreSimulatorService/GUI dependency. 06 Path with no spaces — copied the .app out of a path containing "Application Support" — ruled out a path-quoting issue. The build itself is never in question — xcodebuild reports BUILD SUCCEEDED every time; only the subsequent simctl install step fails. What I'd like feedback on Is this a known issue with this specific Xcode 26.6 / iOS 26.5 Simulator runtime combination — both very recently installed, so possibly a fresh-install/first-boot bug? Is there a required build setting for this Xcode version not yet reflected in commonly-documented XcodeGen/xcodebuild recipes — e.g. an entitlements file now required even for simulator-only, no-team builds, or a different expected code-signing identity/format? Is Info.plist=not bound in the codesign -dv output actually abnormal for an app bundle (as opposed to a framework), and could that be the root cause simctl is choking on?

Connection issue between Apple Watch and Xcode
I'm developing an app for Apple Watch, but I can't connect the Apple Watch to Xcode when I try to run the app on the actual device. I get the following errors: A networking error occurred The device rejected the connection request and A connection to this device could not be established. Timed out while attempting to establish tunnel using negotiated network parameters. The iPhone connects to Xcode without any problem. I've already tried several things without success: Resetting the "trusted computers" settings and trusting the Mac again Restarting all of the devices Making sure all devices are on the same Wi-Fi network On the iPhone, I can see the Developer Mode toggle in Settings, but on the Apple Watch there doesn't seem to be a Developer Mode toggle at all. I'm wondering whether enabling Developer Mode is required in my case. Could anyone tell me how to enable Developer Mode on Apple Watch, or suggest any other way to resolve this issue? Here is my environment: Mac mini (M1, 2020), macOS Tahoe 26.4.1 Xcode 26.4.1 Apple Watch SE 3, watchOS 26.1 iPhone 13, iOS 26.5 Thanks in advance for any help.

Xcode 27 beta - Device Hub - Missing "Slow animations"
Where did the simulator "Slow animations" mode go? I can't find it in the Xcode 27 beta 2 "Device Hub". This feature is incredibly useful. I'm assuming it's a glitch that it's missing, or I'm just not looking in the right place.

CODESIGN -DV ON THE BUILT APP CODESIGN -DV Executable=/QuestionsWeCarry.app/QuestionsWeCarry Identifier=QuestionsWeCarry-******* Format=bundle with Mach-O thin (arm64) CodeDirectory v=20400 size=338 flags=0x2(adhoc) hashes=3+3 location=embedded Signature=adhoc Info.plist=not bound TeamIdentifier=not set Sealed Resources version=2 rules=13 files=4 Internal requirements count=0 size=12 Note Info.plist=not bound — unclear whether this is expected for an ad-hoc-signed bundle app (as opposed to a framework), or is itself a symptom of the underlying problem. Reproduction Minimal, reproducible with the plain command-line tool — no Claude tooling involved in this step: SHELL xcrun simctl install "iPhone 17 Pro" "/DerivedData/Build/Products/Debug-iphonesimulator/QuestionsWeCarry.app" Result (100% reproducible, every attempt): STDERR An error was encountered processing the command (domain=IXErrorDomain, code=13): Simulator device failed to install the application. Missing bundle ID. Underlying error (domain=IXErrorDomain, code=13): Failed to get bundle ID from /QuestionsWeCarry.app Missing bundle ID. Also reproduced with xcrun simctl launch, which fails as a consequence: Isolation steps taken All of the following were tried, and none changed the outcome — the exact same "Missing bundle ID" error occurs every time: 01 Two signing configurations — unsigned/linker-signed (Sealed Resources=none) vs. proper ad-hoc sign (Sealed Resources version=2 rules=13 files=4), plus a manual codesign --force --deep --sign - re-sign pass. Same failure every time. 02 Two simulator destinations — generic/platform=iOS Simulator and a concrete device id for iPhone 17 Pro. 03 Two never-before-used simulator devices — iPhone 17 Pro and iPhone Air — ruling out per-device CoreSimulator state corruption. 04 Erase + cold boot — simctl shutdown, erase, boot immediately before a fresh install attempt. 05 Real Simulator.app GUI running — not just a headless simctl boot — ruled out a CoreSimulatorService/GUI dependency. 06 Path with no spaces — copied the .app out of a path containing "Application Support" — ruled out a path-quoting issue. The build itself is never in question — xcodebuild reports BUILD SUCCEEDED every time; only the subsequent simctl install step fails. What I'd like feedback on Is this a known issue with this specific Xcode 26.6 / iOS 26.5 Simulator runtime combination — both very recently installed, so possibly a fresh-install/first-boot bug? Is there a required build setting for this Xcode version not yet reflected in commonly-documented XcodeGen/xcodebuild recipes — e.g. an entitlements file now required even for simulator-only, no-team builds, or a different expected code-signing identity/format? Is Info.plist=not bound in the codesign -dv output actually abnormal for an app bundle (as opposed to a framework), and could that be the root cause simctl is choking on?

Connection issue between Apple Watch and Xcode
I'm developing an app for Apple Watch, but I can't connect the Apple Watch to Xcode when I try to run the app on the actual device. I get the following errors: A networking error occurred The device rejected the connection request and A connection to this device could not be established. Timed out while attempting to establish tunnel using negotiated network parameters. The iPhone connects to Xcode without any problem. I've already tried several things without success: Resetting the "trusted computers" settings and trusting the Mac again Restarting all of the devices Making sure all devices are on the same Wi-Fi network On the iPhone, I can see the Developer Mode toggle in Settings, but on the Apple Watch there doesn't seem to be a Developer Mode toggle at all. I'm wondering whether enabling Developer Mode is required in my case. Could anyone tell me how to enable Developer Mode on Apple Watch, or suggest any other way to resolve this issue? Here is my environment: Mac mini (M1, 2020), macOS Tahoe 26.4.1 Xcode 26.4.1 Apple Watch SE 3, watchOS 26.1 iPhone 13, iOS 26.5 Thanks in advance for any help.

Select the model in Xcode
How do I select between GPT and Claude, and the model, when opening a new task for the coding agent with the ‘New Conversation’ button in the toolbar?
