dSYM size became thrice for builds generated via xcode 26 compared to xcode 16. These are all release builds.

Hello! I am trying to automate iOS builds for my Unreal Engine game using Unreal Automation Tool, but I cannot produce a functionnal build with it, while packaging from XCode works perfectly. I have tracked down the issue to a missing file. I'm using the Firebase SDK that requires a GoogleService-Info.plist file. I have copied this file at the root of my project, as the Firebase documentation suggests. I have not taken any manual action to specify that this file needs to be included in the packaged app. The Firebase code checks the existence of this file using NSString* Path = [[NSBundle mainBundle] pathForResource: @“GoogleService-Info” ofType: @“plist”]; return Path != nil; If I package my app from XCode using Product -> Archive, this test returns true and the SDK is properly initialized. If I package my app using Unreal Engine's RunUAT.sh BuildCookRun, this test returns false and the SDK fails to initialize (and actually crashes upon trying). I have tried several Unreal Engine tricks to include my file, like setting it as a RuntimeDependecies in my projects Build.cs file. Which enables Unreal Engine code to find it, but not this direct call to NSBundle. I would like to know either how to tell Unreal Engine to include files at the root of the app bundle, or what XCode does to automatically include this file and is there a way to script it? I can provide both versions .xcarchive if needed. Thanks!

After updating Xcode from 16.2 to 16.4, my xcodebuild commands began failing with "Server SSH Fingerprint Failed to Verify" when accessing Bitbucket repositories. During the build process, I could see Xcode's AuthenticationAgent running SSH with these arguments: /usr/bin/ssh -v -F /dev/null -o UserKnownHostsFile=/dev/null -o IdentitiesOnly=yes -o SendEnv=GIT_PROTOCOL git@bitbucket.org git-upload-pack '***.git' Xcode 16.4 appears to be ignoring my local ~/.ssh/known_hosts file and instead using its own managed known_hosts system (stored in IDESourceControlModernKnownSSHHostsDefaultsKey within com.apple.dt.Xcode.plist). My local known_hosts file contains three entries for Bitbucket: ssh-ed25519, ecdsa-sha2-nistp256, and ssh-rsa. After updating Xcode to 16.4 and opening my existing project, Xcode prompted with "Xcode can't verify the identity of a repository hosted on 'bitbucket.org'" and offered a "Trust" button. When I clicked "Trust," Xcode's managed known_hosts only stored the ecdsa-sha2-nistp256 entry for Bitbucket. I was able to resolve the issue by overwriting Xcode's managed known_hosts with the ssh-rsa Bitbucket entry from my local known_hosts file. Also, this behavior for some reason seems to vary between machines after the same Xcode update. So on my machine, Xcode 16.4 ignores the local ~/.ssh/known_hosts. My coworker's Xcode continues to use the local ~/.ssh/known_hosts file and works normally. What could cause Xcode 16.4 to handle SSH known_hosts differently on seemingly identical setups? Is there a hidden configuration that determines whether Xcode uses its managed known_hosts versus respecting the system's SSH configuration? Additionally, why did Xcode only store the ecdsa-sha2-nistp256 host key for Bitbucket when I clicked "Trust" instead of all available host key types, and why doesn't this single key type work?

My post-build script takes the "developeridexport" archive export, zips it up and uses notarytool to notarize it. I then add the .zip to a .dmg disk image. The next step is to codesign the disk image before notarizing that too. The issue is my Developer ID Application certificate is not accessible to the build host. (When I was doing this in Microsoft AppCenter (now defunct), it had a copy of my Developer ID Application certificate.) What steps do I need to take to get the disk image signed for notarization? Thanks! Lance

Xcode will transfer the app to the iPhone, and I can run it on the iPhone, but the Xcode debugger fails to attach. I am using iPhone 14 Pro with iOS 18.6. I've tried connecting via cable, also via network - same issue both ways. The message raised by Xcode says: Could not attach to pid: "6303" Ensure “<a\AppName>” is not already running, and has permission to debug it. I don't know how to determine if I have permission. I assume I do; I am the owner of the account, with admin role.

Hello , am facing issue in submitting my app to store I have submitted my case to apple developer team my case ids "101969263018","101975805043". they told me to submit the report from feedback assistance my case id : FB12141270. but still I don't get any replay form feedback assistance. after that I submitted my case to DTS engineer case id : 2394373. got email to submit some file which I have submitted after that still I don't get any reply from DTS team. please help me to short out this issue. last one month am trying to short out this issue with apple developer team. still I don't get solution.

I am building my first app. I submitted 1.0 to the App Store, it was rejected and I needed to make some changes. Am I unable to upload a new build with changes to testflight before I resubmit those changes? Also, I accidentally removed the app for review, so I cannot respond to the changes they asked. What do I do now? Thank you for your help

What happened to CMD-Option-Click in Xcode 26 for opening a symbol in a new editor split pane? This was one of the most usefull shortcuts. Xcode 26 is a pain to use without it.

Good morning everyone! I have an issue with AutoFillExtension. I think that my integration is correct but I don't see the page with the list. I'm developing a password manager and I see the name of the app in Default Pass in Settings, I see the name of my app when I tap on key to choose credentials but when I tap on my app... don't see anything. Came back Password. Somebody have a list or a tutorial to implement this extension? Thanks 😔

Hello! Trying to find any info about how to add In-App Purchase with application Entitlements.plist file manually (NOT with XCode). Is there any reference within keys and description?

I'm getting an error after clicking on a TestFlight Beta version invite from email. The error says The Apple Account you're currently signed in with, ****@outlook.com, doesn't match the one associated to this invitation. The invitation was sent to the email that I use to sign into my Apple account (it is my apple id) and I am signed into my iphone with that account. What can I do to get the invite to match up and go through with TestFlight?

Hi There We are looking to download the iOS 18.4 Simulator Runtime but due to restrictions on internet access in our company we are unable to use XCode to download the required file. Is there an alternative location we can browse to and download the iOS 18.4 Simulator Runtime file? We checked the downloads sections of the Apple Developer site but can only find 18.2 version of the iOS Simulator Runtime. Thanks

How can you distribute an XCFramework via Swift Package Manager when it has dependencies on other Swift packages? We accomplished this with CocoaPods in order to distribute our closed source SDK that has dependencies, but need to migrate to SPM. Note none of the types from the dependencies are used as part of our module’s public interface - usage is purely internal. I’ve made a lot of progress following these steps for a simple example: Create Framework Project Create a new iOS Framework project in Xcode and name it WallpaperKit In the project settings select the target and verify in Build Settings that Build Libraries for Distribution is Yes then set Skip Install to No Create a new UIViewController subclass, name it WallpaperPreviewViewController, make it public, and add some functionality to it to show a UIImageView Add a new Package Dependency in the project settings, for this example we’ll use https://github.com/onevcat/Kingfisher, and specify exact version 8.5.0 Add internal import Kingfisher and use it in WallpaperPreviewViewController to download and show an image from the web Close the WallpaperKit project Create Hosting App Project (this makes it easier to develop the framework functionality and test it in an app with Xcode building both in the same workspace) Create a new iOS app project and name it WallpaperApp Create a new workspace named WallpaperApp Close the WallpaperApp project Drag and drop WallpaperApp.xcodeproj into the workspace’s sidebar Drag and drop WallpaperKit.xcodeproj into the workspace’s sidebar Switch the scheme to WallpaperKit and build Select WallpaperApp project, then with WallpaperApp target selected, in the General tab under Frameworks, Libraries, and Embedded Content, click + and add WallpaperKit.framework In ViewController.swift, import WallpaperKit and add functionality to present an instance of WallpaperPreviewViewController Run the app and verify it works Create XCFramework In Terminal, cd into WallpaperKit and run xcodebuild archive -scheme WallpaperKit -configuration Release -destination 'generic/platform=iOS' -archivePath './build/WallpaperKit.framework-iphoneos.xcarchive' SKIP_INSTALL=NO BUILD_LIBRARIES_FOR_DISTRIBUTION=YES DEFINES_MODULE=YES Run xcodebuild archive -scheme WallpaperKit -configuration Release -destination 'generic/platform=iOS Simulator' -archivePath './build/WallpaperKit.framework-iphonesimulator.xcarchive' SKIP_INSTALL=NO BUILD_LIBRARIES_FOR_DISTRIBUTION=YES DEFINES_MODULE=YES Run xcodebuild -create-xcframework -framework './build/WallpaperKit.framework-iphonesimulator.xcarchive/Products/Library/Frameworks/WallpaperKit.framework' -framework './build/WallpaperKit.framework-iphoneos.xcarchive/Products/Library/Frameworks/WallpaperKit.framework' -output './build/WallpaperKit.xcframework' Open the build folder and retrieve the XCFramework Create Swift Package Create a new package in Xcode, select Library, and name it WallpaperKitDist Drag and drop WallpaperKit.xcframework into Sources Create a new directory in Sources called WallpaperKitDependencies Create a new Swift file in WallpaperKitDependencies called WallpaperKitDependencies (SPM requires a Swift file to recognize WallpaperKitDependencies as a valid target and fetch dependencies) Open Package.swift and change it to import PackageDescription let package = Package( name: "WallpaperKit", platforms: [ .iOS(.v18) ], products: [ .library( name: "WallpaperKit", targets: ["WallpaperKit", "WallpaperKitDependencies"] ), ], dependencies: [ .package( url: "https://github.com/onevcat/Kingfisher.git", exact: "8.5.0" ) ], targets: [ .binaryTarget( name: "WallpaperKit", path: "./Sources/WallpaperKit.xcframework" ), .target( name: "WallpaperKitDependencies", dependencies: [ "Kingfisher" ], path: "./Sources/WallpaperKitDependencies" ) ] ) Create Test App (to simulate a third-party app using the package) Create a new iOS app project and name it TestApp Add a new Local package selecting the WallpaperKitDist directory that contains Package.swift Import WallpaperKit and use it to present a WallpaperPreviewViewController This works! Though the console logs objc[39953]: Class _TtC10KingfisherP33_6AA794C9C370CDB07604B4D8B99AEAA312BundleFinder is implemented in both /Users/Name/Library/Developer/Xcode/DerivedData/TestApp-capvhjiqxrdgdnbevpkajicnjpcs/Build/Products/Debug-iphonesimulator/WallpaperKit.framework/WallpaperKit (0x100e8bbf8) and /Users/Name/Library/Developer/CoreSimulator/Devices/E0AF13C2-874C-47B9-B864-72AF3E4D5D4B/data/Containers/Bundle/Application/AF32011A-92E7-4E26-9A97-9F0C25C07863/TestApp.app/TestApp.debug.dylib (0x101a543b0). This may cause spurious casting failures and mysterious crashes. One of the duplicates must be removed or renamed. I thought using internal import Kingfisher (or @_implementationOnly import Kingfisher) would have resolved this, but seems to make no difference compared to just import Kingfisher. I suspect it might not be an issue as long as the Kingfisher version number specified in the distribution Package.swift matches the version used in the framework project (and the app does not add a different version as a dependency), but not positive. Can these warnings be resolved, or is it not a concern in this setup? Is this the best solution to distribute an XCFramework via Swift Package Manager that has dependencies on other Swift packages for now or is there a better approach? Thanks!

I’m testing Game Activities in my Unity project with the new Apple.GameKit 2025-beta1 plugin. When I go into Xcode- Debug → GameKit → Manage Game Progress → Leaderboards → and click the generated link: If my app is already running in the background, the link opens the app and my handler (Apple.GameKit.GKGameActivity.WantsToPlay += OnWantsToPlay;) fires as expected. I can read the activity and route the player to the right level. If the app is completely closed, clicking the same link launches the app, but my OnWantsToPlay listener is never invoked. The app just boots normally and the activity intent seems lost. I’ve tried to subscribe as early as possible (in Awake() of my bootstrap scene, also tested with RuntimeInitializeOnLoadMethod(RuntimeInitializeLoadType.BeforeSplashScreen)]). Nothing works. Also, “Get Started with Game Center” video only demonstrates activation when the app already running, not a cold start from a Game Activity link. What am I missing?

I'm currently running Xcode 26 beta 7; it comes with macOS 26 beta 6 and can download iOS 26 beta 6. I can compile and test my app on simulators, but to upload the app to TestFlight I need a version of the Platform support more recent than beta 6. How can I download beta 9? In Settings -> Components I see only beta 6.

Hello Apple team, I am using xctrace to record an Allocations trace on iOS. For example: xctrace record --template "Allocations" --launch com.example.myapp --time-limit 30s --output alloc.trace After recording, I can export the results in Allocations List format (flat list of allocations) using: xcrun xctrace export --input ./alloc.trace --xpath '/trace-toc/run/tracks/track[@name="Allocations"]/details/detail[@name="Allocations List"]' --output ./alloc.xml This works fine and produces an XML output. However, what I really need is to export the data in Call Tree format (as shown in Instruments GUI). I checked xctrace export --help, but it seems that the Allocations template only supports the List view for export, not the Call Tree breakdown. My question is: 👉 Is there a way to export an Allocations trace in XML with Call Tree details using xctrace? 👉 If not, is there an API or recommended workflow to automate this instead of exporting manually from Instruments GUI? Thanks in advance for your help!
