Some Macs recently received a macOS system update which disabled the simulator runtimes used by Xcode 15, including the simulators for iOS, tvOS, watchOS, and visionOS. If your Mac received this update, you will receive the following error message and will be unable to use the simulator: The com.apple.CoreSimulator.SimRuntime.iOS-17-2 simulator runtime is not available. Domain: com.apple.CoreSimulator.SimError Code: 401 Failure Reason: runtime profile not found using "System" match policy Recovery Suggestion: Download the com.apple.CoreSimulator.SimRuntime.iOS-17-2 simulator runtime from the Xcode To resume using the simulator, please reboot your Mac. After rebooting, check Xcode Preferences → Platforms to ensure that the simulator runtime you would like to use is still installed. If it is missing, use the Get button to download it again. The Xcode 15.3 Release Notes are also updated with this information.

Xcode 26.2 RC has been out for over 24 hours and it's still not possible to submit apps.

I'm making a wrapper library to abstract away some of the 'missing platform support' of DeclaredAgeRange until hopefully it expands to additional platforms. When I'm trying to fully enumerate all of the cases of AgeRangeDeclaration, which they all state available starting 26.0 (mysteriously added in Xcode 26.2 beta), the app crashes due to a missing symbol at launch time. This happens both for Xcode 26.1, 26.2 beta 2, and matching Xcode Cloud builds. So I've isolated it beyond "doesn't work on my machine". I just made a handful of crashes and attached a sysdiagnose to a fresh feedback. FB21121092 - DeclaredAgeRange: Eligibility property and new declaration cases unavailable on iOS 26.1 device contradicting documentation - causes runtime symbol not found crash If anyone is curious what these crashes look like I've attached the DiagnosticPayload.jsonRepresentation() generated from one of my favorite frameworks, MetricKit. Very clearly articulated in the diagnostic metadata you can see the symbol not found. "diagnosticMetaData" : { "platformArchitecture" : "arm64e", "terminationReason" : "Symbol not found: _$s16DeclaredAgeRange0bC7ServiceV0bC11DeclarationO14paymentCheckedyA2EmFWC\nReferenced from: <1894EDCB-3263-3604-8938-97D465FF3720> \/Volumes\/VOLUME\/*\/PerformanceOrganizer.app\/PerformanceOrganizer\nExpected in: <B8FD2C23-0CC9-3D94-902D-875900307A7A> \/System\/Library\/Frameworks\/DeclaredAgeRange.framework\/DeclaredAgeRange", "exceptionType" : 10, "appBuildVersion" : "745", "isTestFlightApp" : true, "osVersion" : "iPhone OS 26.1 (23B85)", "bundleIdentifier" : "dev.twincitiesapp.performanceorganizer", "deviceType" : "iPhone18,1", "exceptionCode" : 0, "signal" : 6, "regionFormat" : "US", "appVersion" : "2.0.0", "pid" : 22987, "lowPowerModeEnabled" : false } DiagnosticPayload.json This is the offending code in a type I control and make available on other platforms but leave unused. extension AgeRangeDeclaration { // A factory or initializer that takes the AgeRangeService.AgeRangeDeclaration and maps to the common AgeRangeDeclaration type public init?(platform value: AgeRangeService.AgeRangeDeclaration?) { guard let value else { return nil } switch value { // Xcode 26.1 visible cases case .selfDeclared: self = .selfDeclared case .guardianDeclared: self = .guardianDeclared // Xcode 26.2 visible cases // This is the first culprit, all of the following symbols would crash, this is just the first case .checkedByOtherMethod: self = .checkedByOtherMethod case .guardianCheckedByOtherMethod: self = .guardianCheckedByOtherMethod case .governmentIDChecked: self = .governmentIDChecked case .guardianGovernmentIDChecked: self = .guardianGovernmentIDChecked case .paymentChecked: self = .paymentChecked case .guardianPaymentChecked: self = .guardianPaymentChecked @unknown default: // Apple added new cases in Xcode 26.2 betas that were available in iOS 26.0, // so it is probable that this could happen again.

As a side note, thank you for this property, it will let me check what states I need to perform extra checks for in a clean way, I just will need it to now not crash my app on 26.0 and 26.1 runtime devices. :) Edit: DTS did confirm on a comment I had in another thread that this is a bug. Now just to wait for an Xcode beta update. https://developer.apple.com/forums/thread/807906?answerId=867205022#867205022 In any case, this is a great example of how MetricKit totally rocks capturing things other off the shelf crash tools might not have a chance to get. I did have to roll back my TestFlight to an earlier build, but MetricKit was there to send me the previous crashes as soon as the app could launch. Thanks MetricKit team!

Just recently, any pkg file that I create with pkgbuild will install the Payload's application as a zero-byte file in the /Applications directory. This has been working for years without issue for me. Here are the commands I am using with company specific items replaced: pkgbuild --analyze --root MyApplicationRootDirectory standalone.plist plutil -replace BundleIsRelocatable -bool NO standalone.plist pkgbuild --identifier MyIdentifier --version 1.0 --install-location /Applications --root MyApplicationRootDirectory --component-plist standalone.plist --sign 'Developer ID Installer: MyCompany (MySignId)' --timestamp installer.pkg Any ideas on what could be causing the issue? I have verified the following: The application being added to the pkg is both signed and notarized using the correct Developer ID Application certificate. The resultant pkg file is both signed and notarized using the Developer ID Installer certificate. Verified the pkg contents using "pkgutil --expand" to dump the contents. Verified the pkg's Payload contents by extracting the data using "cat Payload | gunzip | cpio -1". This results in an application file that is a binary match for file added in the "pkgbuild --root" argument. My application is the only file within the directory passed to the "pkgbuild --root" argument. There are no warnings in the System Settings / Privacy & Security Panel when running the package installer. I have a valid Mac Developer account. I am building the application and the pkg file on the same computer. Thank you for any insight.

I'm experiencing a strange issue where ASWebAuthenticationSession works perfectly when running from Xcode (both Debug and Release), but fails on TestFlight builds. The setup: iOS app using ASWebAuthenticationSession for OIDC login (Keycloak) Custom URL scheme callback (myapp://) prefersEphemeralWebBrowserSession = false The issue: When using iOS Keychain autofill (with Face ID/Touch ID or normal iphone pw, that auto-submits the form) -> works perfectly When manually typing credentials and clicking the login button -> fails with white screen When it fails, the form POST from Keycloak back to my server (/signin-oidc) never reaches the server at all. The authentication session just shows a white screen. Reproduced on: Multiple devices (iPhone 15 Pro, etc.) iOS 18.x Xcode 16.x Multiple TestFlight testers confirmed same behavior What I've tried: Clearing Safari cookies/data prefersEphemeralWebBrowserSession = true and false Different SameSite cookie policies on server Verified custom URL scheme is registered and works (testing myapp://test in Safari opens the app) Why custom URL scheme instead of Universal Links: We couldn't get Universal Links to trigger from a js redirect (window.location.href) within ASWebAuthenticationSession. Only custom URL schemes seemed to be intercepted. If there's a way to make Universal Links work in this context, without a manual user-interaction we'd be happy to try. iOS Keychain autofill works The only working path is iOS Keychain autofill that requires iphone-authentication and auto-submits the form. Any manual form submission fails, but only on TestFlight - not Xcode builds. Has anyone encountered this or know a workaround?

Validation failed Missing app icon. Include a large app icon as a 1024 by 1024 pixel PNG for the 'Any Appearance' image well in the asset catalog of apps built for iOS or iPadOS. Without this icon, apps can't be submitted for review. For details, visit: https://developer.apple.com/documentation/xcode/configuring-your-app-icon. (ID: 525f6327-6859-4ae7-977b-7951423127a6) getting this error while archive and validation then validation failed and got this error But in my xcode each icon is present and when i build the app then in simulator or a real phone the icon is present but while archive and validation then validation failed also i have tried a lot solution but unable to resolve this.

The buttons in the navigation bar are not available in the element tree after iOS 26 upgrade of the test phones. The same IPA version, the same XCode version, but different trees on different phones. There is no way to automate UI testing for these missing buttons. # ios 18 NavigationBar, 0x108e0c3c0, {{0.0, 47.0}, {390.0, 44.0}}, identifier: 'Profile' Button, 0x108e0c500, {{8.0, 47.0}, {43.0, 44.0}}, identifier: 'UserProfileSceneViewController_profile_back_button', label: 'chevronLeftIcon' StaticText, 0x108e0c640, {{169.3, 58.0}, {51.3, 22.0}}, label: 'Profile' Button, 0x108e0c780, {{339.0, 47.0}, {43.0, 44.0}}, identifier: 'UserProfileSceneViewController_settings_bar_button', label: 'Settings' # ios 26 NavigationBar, 0x13d63c8c0, {{0.0, 47.0}, {428.0, 54.0}}, identifier: 'Profile' StaticText, 0x13d63ca00, {{188.3, 58.0}, {51.3, 22.0}}, label: 'Profile'

I have a Unity AR project that I want to build for iOS. The build in Unity succeeds just fine, but when it opens in XCode, whatever I do, it keeps showing this error in GameAssembly: "Command PhaseScriptExecution failed with a nonzero exit code". This error also doesn't open when choosing "Reveal in Log". I have added the IL2CPP package in the Unity version, deleted and reentered scenes and no issue on Unity's side. On XCode I signed in with my developer account, tried deleting derived data, made a clean build and still the issue persists.

I'm really sick of Apple and their BS kickbacks they get from github and the other source control outfits restricting what source control packages we can use inside of XCode. We have used Code Commit with AWS for YEARS! We are not switching but apple's Xcode will not allow us to add it as an account. We used to be able to use it, but Apple took away the GIT account setup so now you have to use one of their kickback outfits. This is complete BS Apple. Even AWS realized how important Code Commit is and made it available to everyone again and pledged full support going forward. How about you get off your collective sixes and do the same. I'd like an explanation on why you took away the one feature that allows us to use what works for us.

I have been using Xcode Version 26.1.1 on macOS Tahoe Version 26.1. In VIM mode, whenever I quickly tap d twice, to delete the complete line, most of the time Xcode crashes. Is anyone else facing this issue? Should I move to any older version of Xcode or any other solve for this?

I have an Xcode app where currently txt files in the project display text data as a list. I can search through the lists and have buttons that will swap between different lists of information that you can look through. The next task is I have URL connections to docx files on a SharePoint site. I am trying to use an URLsession function to connect to the URL links to download the documents to the document directory then have the application read the doc information to then be displayed as the txt info would. The idea is that the docx files are a type of online update version of the data. So when the app is used and on wifi, the app can update the list data with the docx files. I have code set up that should access the URL files but I am struggling to figure out how to read the data and access from this Documents directory. I have been looking online and so far I am at a loss on where to go here. If anyone can help or provide some insight I would greatly appreciate it. I can try and provide code samples to help explain things if that is needed.

I can create an ipa file with vs using the wildcard bundle identifier but this is rejected by apple when I upload with the Transporter app saying invalid identifier and no distribution profile/certificate. When I create a new distribution profile with the correct XC identifier and distribution certificate and try to archive with visual studio publish says the bundle id is not a match for the distribution profile with iOS? This is a net 10 net maui project and my first build attempt

I've recently run into an issue in Xcode where the sks editor's preview canvas just vanishes for every project on my computer. I don't think it is an issue with my sks files because this works as expected on another computer with the same files, and when it happens it happens for ALL sks files in all projects. There used to be menu items to toggle the canvas and its settings, but those are now gone for me in sks files (they show up for swift files that have previews, however). Any idea what is going on here? How do I get the canvas back? I literally cannot get any work done on my primary computer because of this...

I am constantly reaching my daily ChatGPT limit and even though it's recommending that I log in, I already am. What can I do to fix this?

It has been two years since I wrote my a SwiftUI app, and I wanted to start again in Xcode 26. I can no longer see the attributes inspector when I select an element in the canvas. This was an Xcode feature that was very helpful as I am still a novice. Has this feature been deprecated in Xcode 26? And if not, please help explain how I can find and use it.

Hi, I am trying to update my apps and i couldn't do it, can anyone please help? this is what happened to me. Once my membership renewed, i couldn't compile my apps due to signing error. here is the error message: Xcode archive done. 31.7s Failed to build iOS app Error (Xcode): Communication with Apple failed: Your team has no devices from which to generate a provisioning profile. Connect a device to use or manually add device IDs in Certificates, Identifiers & Profiles. https://developer.apple.com/account/ /Users/tony/vn246/ios/Runner.xcodeproj when I go to the portal developer.apple.com/account to create the Provisioning Profile manually then it said there is no device, and when i go into the Devices section then the machine uuid is added and it's there and registered, i had always been compiling with it before the old membership was expired. I tried to remove those and re-added and the error still persisted. P.S.: I renewed all my certificates (removed old and recreated new) thank you

Stale TBD Files Cause Runtime Crash When Framework Changes from Dynamic to Static Summary When using EAGER_LINKING=YES, Xcode generates TBD files for dynamic frameworks. When a framework changes from dynamic to static, Xcode doesn't remove the stale TBD, causing dyld: Library not loaded crash at runtime.

Hi, We are trying to use Apple Security API for KeyChain Services. Using the common App Group : Specifying the common app group in the "kSecAttrAccessGroup" field of the KeyChain query, allowed us to have a shared keychains for different apps (targets) in the app group, but this did not work for extensions. Enabling the KeyChain Sharing capability : We enabled the KeyChain Sharing Ability in the extensions and the app target as well, giving a common KeyChain Access group. Specifying this in the kSecAttrAccessGroup field also did not work. This was done in XCode as we were unable to locate it in the Developer portal in Indentifiers. We tried specifying "$AppIdentifier.KeyChainSharingGroup" in the kSecAttrAccessGroup field , but this did not work as well The error code which we get in all these 3 cases when trying to access the Keychain from the extension is error code 25291 (errSecNotAvailable). The Documentation says this error comes when "No Trust Results are available" and printing the error in xcode using the status says "No keychain is available. The online Documentation says that it is possible to share keychain with extensions, but by far we are unable to do it with the methods suggested. Do we need any special entitlement for this or is there something we are missing while using these APIs? We really appreciate any and all help in solving this issue! Thank you

I'm trying to add a confirmationDialog to an app, so that the user can select an option from a menu that comes up from the bottom of the screen. This works perfectly for an iOS 18 simulator, but the behavior changes when the simulator is running iOS 26.1. Is this the intended behavior of .confirmationDialog in iOS 26.1?

Hi, I have an iOS project with the following app targets: main iOS application a notification service extension 5 static libs containing some swift files with public methods 1 dynamic framework with above static libs as dependencies. The framework only contains 2 files - a default .h file and 1 .exp file. This exports file contains mangled-names of all the public methods that are exposed by the 5 static libs present as framework's dependencies. I obtained these symbols using the nm command for each static lib. The main iOS app target has 2 dependencies - the framework and the notification extension. The notification extension only depends on the framework. This setup works perfectly fine. I wanted to understand: If using the exports file is the only way to make this setup work? If not, what else can I do? What way does Apple recommend? According to my requirements, I only need at-most 2-3 functions to be exposed by the framework - thus using a exports file just for that seems to bug me. Thank you.
