I inherit from a protocol that implements in its extension those functions, that should not be required by the adopting class and instead I get those errors. Could someone explain why those errors appear and how to fix it.

It annoys me that Xcode keeps downloading Simulators automatically, even though I haven't asked for them. Under Settings > Components > Other Installed Platforms I see iOS Simulator iOS 18.0 uptil 18.5. These are eating space in /Library/Developer/CoreSimulator/Caches/dyld/25E253. Is there a way to prevent these automatic downloads?

Hi, I'm setting up Xcode and after updating MacOS to 15.2 and Xcode to 16.2, I cannot download the Predictive Code Completion Model. I've done some research and I haven't found any solution, specially since most people suggest that it randomly fixed itself, which for me hasn't been the case. I've tried restarting my Mac, uninstalling and reinstalling Xcode multiple times, I've also reinstalled MacOS from Recovery and haven't found any success (I'm also not running Xcode inside a VM, as I've seen this can cause some problems in this case). This is the error that I receive when I attempt to download the model: And here are the details: The operation couldn’t be completed.

Codex will no longer be available in Xcode 26.3 starting on Friday, May 8th. Please upgrade to Xcode 26.4 or later to continue using Codex.

We came across reports on Medium and Apple Developer Forums suggesting that ApplicationToken and ActivityCategoryToken values issued by the FamilyControls framework are not guaranteed to be stable, that iOS may silently re-issue new tokens for the same apps after OS or app updates, making any previously stored tokens invalid. We are storing FamilyActivitySelection tokens encoded via JSONEncoder to a backend for long-term use, and relying on them inside a DeviceActivityMonitorExtension to restore and apply shields when a schedule fires. What we're trying to understand is: is this token instability still an active problem in iOS 16/17/18/26, and when a token does become invalid, does JSONDecoder actually throw a DecodingError giving us a clear signal, or does it decode successfully and ManagedSettingsStore just silently ignore the stale tokens with no error at all? On Medium, We Found That The Token Mutation Problem One of the more painful bugs in real production apps: application tokens are not guaranteed to be stable forever. iOS can silently issue new, different tokens for the same app. If your store contains the old token and the Shield delegate receives a new one, the delegate has no way to match them — it doesn’t know which store is responsible for the shield, or which blocking “profile” caused it. This has been reported by multiple developers of real Screen Time apps and confirmed across several Apple Developer Forum threads. There is no official fix yet. The workaround is defensive: when the ShieldConfigurationDataSource or ShieldActionDelegate receives a token you don't recognise, fall back to a generic shield UI rather than crashing or returning empty data. And never rely on token identity as a long-term stable key in your persistence layer — always re-derive from a fresh FamilyActivityPicker selection when the user re-activates a profile.

Description Xcode 26.4.1 crashes immediately on launch with a code signature error. The issue exists on macOS 26.4.1 and persists after upgrading to macOS 26.5 (25F5058e) and attempting 26.6 beta. Crash Details: Exception Type: EXC_BAD_ACCESS (SIGKILL (Code Signature Invalid)) Termination Reason: Namespace CODESIGNING, Code 2, Invalid Page Key symbols: dyld3::MachOFile::trieWalk, dyld4::JustInTimeLoader::applyFixups, dyld4::Loader::forEachBindTarget All Steps Tried (All Failed): Fresh reinstall from Mac App Store and .xip from Developer website Multiple sudo xattr -cr + sudo codesign --force --deep --strict --options=runtime --sign - Deleted all Xcode caches, DerivedData, and preferences Tested in a brand new user account (same crash) Downgraded Xcode to older versions macOS remains on 26.4.1 (issue existed here) and upgraded to 26.5 / attempted 26.6 beta — still same crash Refreshed Apple Worldwide Developer Relations certificates Multiple restarts The crash report is identical every time. System Information Model: MacBook Pro (M1 Pro, MacBookPro18,1) macOS: 26.5 (25F5058e) — issue started after upgrade from 26.4.1 Xcode: 26.4.1 (24909.0.3) SIP: Enabled Developer Mode: Enabled Additional Notes Other applications launch normally. This appears to be a system-level compatibility issue introduced in macOS 26.5's stricter code signing validation on mapped files / chained fixups. Request Is there a known workaround? Is Apple preparing a fix in a future macOS 26.5 patch or Xcode update? What additional information would help? Thank you!

Hello Apple Developer Community, I'm seeing a persistent crash in my iOS app reported via Firebase Crashlytics. The issue only started appearing on devices running iOS 26.3.0 and above (the crash does not occur on lower iOS versions, and it's unrelated to my app's version number). Key points: My app does NOT use any Text-to-Speech (TTS) features whatsoever. No AVSpeechSynthesizer, no Speech framework, no related APIs called from our code. My app is primarily written in Objective-C (with some Swift components possibly via dependencies). The crash stack is entirely within Apple's private TextToSpeech framework, specifically in ausdk::BufferAllocator::instance(). I suspect it might be indirectly triggered by a third-party ad SDK (e.g., Google Mobile Ads, AppLovin, etc.) that could be loading or interacting with accessibility features in the background — but this is just a hypothesis, as I have no direct evidence yet. Here is one representative crash log: Crashed: com.apple.root.user-initiated-qos.cooperative 0 TextToSpeech 0x6bb00 ausdk::BufferAllocator::instance() + 99800 1 TextToSpeech 0xf8c60 ausdk::BufferAllocator::instance() + 677688 2 TextToSpeech 0xf8c60 ausdk::BufferAllocator::instance() + 677688 3 TextToSpeech 0x1a0b9c ausdk::BufferAllocator::instance() + 1365620 4 libswift_Concurrency.dylib 0x628b4 swift::runJobInEstablishedExecutorContext(swift::Job*) + 288 5 libswift_Concurrency.dylib 0x63d28 swift_job_runImpl(swift::Job*, swift::SerialExecutorRef) + 156 6 libdispatch.dylib 0x13f48 _dispatch_root_queue_drain + 364 7 libdispatch.dylib 0x146fc _dispatch_worker_thread2 + 180 8 libsystem_pthread.dylib 0x137c _pthread_wqthread + 232 9 libsystem_pthread.dylib 0x8c0 start_wqthread + 8 The crash occurs on a background cooperative queue (Swift Concurrency). Questions: Has anyone else seen crashes inside ausdk::BufferAllocator::instance() in TextToSpeech on iOS 26.3.0+ even without using TTS in their app? Could a third-party ad SDK be causing the TextToSpeech framework to load unexpectedly (e.g., via accessibility preloading)? Is this a known bug in iOS 26's Spoken Content / Speak Selection features? Any workarounds or fixes from Apple? Any insights, similar reports (especially from Objective-C based apps), or advice would be greatly appreciated! Thanks!

Any idea why this might happen and how to stop it? I try to run a simple iOS app from Xcode, in the iOS Simulator, and it takes a very long time to start. I see "mediaanalysisd" in the Activity Monitor, taking a lot of CPU, fans are blowing. When I quit the simulator, the mediaanalysisd process goes away and the fans stop. Maybe related: I have a 2020 MacBook Pro with Intel chips, and general it's been having more bogged down performance and fans blowing that in years past. My suspicion is the latest macOS updates are not caring much about Intel CPUs...

Hello! I've been trying to automate tests using Appium/XCUITests in a React Native APP, but I'm finding many blockers. They are related to the amount of nested elements in the "DOM" in which the XCUItest can not go deeper to get all the elements we need. snapshotMaxDepth -> The XCUITest does not support more than 60 value, otherwise it returns the following error: Got response with status 404: {"value":{"error":"stale element reference","message":"The previously found element "Application 'xyz.xxx.xxx'" is not present in the current view anymore.

Is there any solid documentation to get the controllers to work in my experience? I am having the hardest time figuring out how to get the controllers to work properly. I get them to work in the system, but within my project, they work, but inconsistent and some buttons will not register taps, grabs, grips, etc

Hello. I don't know if this is a place to ask questions and get solutions, but I think there will be a lot of experts gathered, so I'm posting it. I'm a student who recently started learning Xcode. In the book, you can see a graph-shaped pop-up window by pressing the eye-shaped quick look button in the Xcode playground, but I can't find that button in my Xcode 26 version. Can you tell me where the button is? I'm sorry for asking such a basic question.

I just noticed this but am curious: Why does Xcode use list.bullet SF Symbol to toggle the "navigators" (sidebar) instead of sidebar.left? For the inspectors Xcode uses "sidebar.right" but I don't understand why the left sidebar uses a different icon from the right sidebar? Shouldn't the left sidebar icon match the right sidebar (just flipped)? Am using the wrong SF Symbol in my app to toggle the sidebar? Is the list.bullet the recommended symbol for this now? Every other app seems to use sidebar.left.

Xcode 26.4.1, iOS 26.4.2, watchOS 26.4, Apple Watch Ultra 3 not appearing as development device. Can't do any IWatch development

For me it looks like Xcode 26 has problems reading SPM packages from a locally hosted BitBucket git solution. While Xcode 16 work perfectly fine, Xcode 26 fails to load and gives "Server SSH Fingerprint Failed to Verify" as error description. Cleaning build data and DerivedData sometimes makes loading work. Any change in Package dependencies will break it again. Anyone having same problems? How do you handle it?

I have a brand new iPhone 15 with iOS 17, paired with a watch on WatchOS10. In devices and simulators, the iPhone 15 and Watch 10 device show up as disconnected (with the globe icon I think is what it is?) and if I click on either of them, that icon changes to a spinner, and the main window says "Xcode will continue when the operation completes", but it NEVER completes. This makes the device not usable for development. In addition, I have updated my iPad to iOS17, and it doesn't even show up at all in the devices and simulator list, even though it is enabled for developer mode. I have toggled developer mode off and on (thus rebooting). I have quit and restarted Xcode. I have even rebooted the Mac. Nothing helps. This is incredibly frustrating.

Currently, when creating a new Git remote in Xcode, the visibility for the new repository is set to public by default. It would be safer if it were set to private by default. FB22673051 https://github.com/feedback-assistant/reports/issues/797

Hello, My request to get the family control entitlement for distribution has been approved on June 30, 2025, for my app with bundle id io.onelife.app.ios. I added a device report extension to it recently, but since then I'm not able to upload a new archive to testflight. The upload fails with error: exportArchive Provisioning profile "iOS Team Store Provisioning Profile: io.onelife.app.ios.YoholDeviceActivityReportExtension" doesn't include the com.apple.developer.family-controls entitlement. I ticked the checkbox in developer.apple.com -> identifiers -> YoholDeviceActivityReportExtension -> Capability, and it seems to have created a new request 9AHY2B7947 on April 23, 2026. Did I miss something ? Should I just wait to have it approved a second time ?

I switch between Project / Tests / Breakpoints using top left pane 100s times a day. I also switch to search using CMD-Shift-F. In Xcode 26.4 I have to tap the <> to open menu. Is there a way to bring back the old behavior. Does any of the UX guys who worked on that feature use Xcode on daily basis? This is so bad :(

I am using objective-c to develop a custom keyboard on iPhone X to run in landscape orientation. I want my to make use of the full iPhone X screen and have my custom keyboard layout extending from left edge to right edge of the screen in landscape orientation.No matter what I try, my custom keyboard layout stays confined in the safe area.What do you recommend?Thank you
