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?

‌Using Xcode 26, the built package encounters device compatibility issues — while it installs successfully on supported iPhone devices, but it crashes immediately upon launch and cannot run normally.‌‌In previous versions of Xcode, the same "minimum deployment" setting in the project did not cause such compatibility issues.‌ The app built with Xcode 26 shows the following behavior when installed and tested on various devices:‌ iPhone6p iOS12.5.8 fails to run 2.iPhone6 iOS11 fails to run 3.Iphone6 iOS12.5.7 fails to run 4.iPhone7 iOS12.1.3 ok 5.iPhoneX iOS 12.2 ok 6.iphone6s plus iOS10.3.1 ok 7.iphoneXS. iOS 12.1.4 ok 8.iPhone11 iOS 13.6.1 ok 9.iPhone7. iOS 13.7 ok We have tested and found that an iPhone 6s Plus running iOS 10.3.1 can normally run the app. We would like to know whether apps built with Xcode 26 are inherently incompatible with iPhone 6 and older devices. Has Xcode 26’s underlying build environment removed full support for the A8 chip, resulting in binary files containing instructions or memory models that older devices cannot parse? ‌Looking forward to your reply‌.

Hi everyone, (you can answer in french) I’m french-rookie in xcode, and I have a problem: I’m trying to choice my custom font to add it in my Main.storyboard button, but it not works. I have my « Font provided by application » line in my Info.plist, with the name of my font in [0] (See images below) When I’m on storyboard button, I chose « custom » in font selector, then display font list but my custom font doesn’t appear. I already tried to install the font in my mac, but still stucked, nothing change 😭 Could you help me please? Thanks a lot (I specify that I scrupulously followed the way of doing explained on the Apple official page: Adding a Custom Font to Your App )

At the Platform State of the Union, Apple demoed clicking a ✨ button in the Xcode toolbar to use Apple Intelligence in Xcode. I don't see that button in Xcode Version 26.0 beta (17A5241e). Am I missing it? It's supposed to be in the upper-left corner, right? Do I need to turn it on or something? I'm on macOS 15.5 Sequoia, on a 16-inch, 2021 MacBook Pro

I downloaded the latest version of Xcode 26 (beta). I'm running Max OS 15.5. How can I use Claude 4 Opus? I can't wait to try this out. Thanks in advance!

Hi! In neither Xcode 16.2 beta 3 nor Xcode 16.2 I am able to get App Shortcuts Preview to recognise my Shortcuts. In either supported language I always get "No Matching Intent" as the result. Flexible matching is enabled, minimum deployment target is iOS 18. The Shortcut phrases do work in the simulator and on device. Is this a known issue or am I missing something?

I have designed a new icon for my app/Tahoe in Icon Composer (launched from within Xcode)but I simply cannot get it to show up. The documentation for Icon Composer spends a lot of time describing how to design the icons but goes distressingly vague/silent on how one might use it. It suggests that I should drag the file to Xcode and it will guide me as to where to put it. The app continues to use the old (pre-Tahoe) icon. I don't get any change of behaviour and I don't know what to name the file. I assume that there are no other settings that I have to change. I can't find anything on the web or in Apple's documentation: maybe I'm missing something obvious! My app is a working NSDocument-based Cocoa project. Any suggestions please. Tahoe 26.0.1, Xcode 26.0.1, Apple M1 Max MBP.

I am using SwiftData for my model. Until Xcode 15 beta 4 I did not have issues. Since beta 5 I am receiving the following red warning multiple times: 'NSKeyedUnarchiveFromData' should not be used to for un-archiving and will be removed in a future release This seems to be a CoreData warning. However, I am not using CoreData directly. I have no way to change the config of CoreData as used by SwiftData. My model just uses UUID, Int, String, Double, some of them as optionals or Arrays. I only use one attribute (.unique).

I have an AppleTV app which I released in 2016. I've updated it and released a new version every year without much hassle. This year, with tvOS 17.2, the layered app icon isn't working right. This is a two-layer image made with PNGs. When it's selected, it looks right and the layers move correctly: But when it's not selected, the background layer disappears: Screenshots are from the simulator but it also happens on the device. It's inconsistent; sometimes it's the front layer that disappears. Occasionally both layers work, but I can't tell why. I've spent a day trying everything. Very frustrated. The icon previews correctly in Xcode and in Parallax Viewer. The image sizes are correct: 400 x 240 for Small, 800 x 480 for Small@2x, 1280 x 768 for Large. The back layer is a non-transparent PNG. I tried adding a Large@2x set. Didn't help. Originally I had a three-layer image with no middle layer PNG. I deleted the empty middle layer, but that didn't help. All the PNG files are from GnuIMP. Same color space, even. I was using the filenames tvicon-back-s.png and tvicon-back-s@2x.png. I tried taking out the @ sign in case that was confusing Xcode. (It never has before, but I am flailing here.) Anybody have any clues? If it's an Apple bug and there's nothing I can do, I'm going to just push the release button and hope it fixes itself someday.

I am building a bundle target for macOS 12 and later using Xcode. The bundle is not a standalone app, but a plug-in that is loaded by a host app. The code is written in Swift and uses the new Span API which is available in the OS-provided standard library in macOS 26 and backdeploys to macOS 10.14.4+. Xcode should instruct the linker to include libswiftCompatibilitySpan.dylib in the compiled bundle to provide this backdeployment, but that does not happen. SwiftPM does this additional linking by adding an rpath. When trying to load the bundle using the NSBundle.loadAndReturnError() API, I get the following error on macOS 15 (and no error on macOS 26): Error Domain=NSCocoaErrorDomain Code=3588 "dlopen(.../MyBundle.someBundle/Contents/MacOS/MyBundle, 0x0109): Library not loaded: @rpath/libswiftCompatibilitySpan.dylib Referenced from: <CE92806C-94B7-367E-895D-EF6DF66C7FC2> .../MyBundle.someBundle/Contents/MacOS/MyBundle Reason: tried: '/usr/lib/swift/libswiftCompatibilitySpan.dylib' (no such file, not in dyld cache), '/System/Volumes/Preboot/Cryptexes/OS/usr/lib/swift/libswiftCompatibilitySpan.dylib' (no such file), '/private/Frameworks/libswiftCompatibilitySpan.dylib' (no such file), '.../MyBundle.someBundle/Contents/MacOS/../Frameworks/libswiftCompatibilitySpan.dylib' (no such file), '/usr/lib/swift/libswiftCompatibilitySpan.dylib' (no such file, not in dyld cache), '/System/Volumes/Preboot/Cryptexes/OS/usr/lib/swift/libswiftCompatibilitySpan.dylib' (no such file), '/private/Frameworks/libswiftCompatibilitySpan.dylib' (no such file), '.../MyBundle.someBundle/Contents/MacOS/../Frameworks/libswiftCompatibilitySpan.dylib' (no such file)" UserInfo={NSLocalizedFailureReason=The bundle couldn’t be loaded., NSLocalizedRecoverySuggestion=Try reinstalling the bundle., NSFilePath=.../MyBundle.someBundle/Contents/MacOS/MyBundle, NSDebugDescription=dlopen(.../MyBundle.someBundle/Contents/MacOS/MyBundle, 0x0109): Library not loaded: @rpath/libswiftCompatibilitySpan.dylib Referenced from: <CE92806C-94B7-367E-895D-EF6DF66C7FC2> .../MyBundle.someBundle/Contents/MacOS/MyBundle Reason: tried: '/usr/lib/swift/libswiftCompatibilitySpan.dylib' (no such file, not in dyld cache), '/System/Volumes/Preboot/Cryptexes/OS/usr/lib/swift/libswiftCompatibilitySpan.dylib' (no such file), '/private/Frameworks/libswiftCompatibilitySpan.dylib' (no such file), '.../MyBundle.someBundle/Contents/MacOS/../Frameworks/libswiftCompatibilitySpan.dylib' (no such file), '/usr/lib/swift/libswiftCompatibilitySpan.dylib' (no such file, not in dyld cache), '/System/Volumes/Preboot/Cryptexes/OS/usr/lib/swift/libswiftCompatibilitySpan.dylib' (no such file), '/private/Frameworks/libswiftCompatibilitySpan.dylib' (no such file), '.../MyBundle.someBundle/Contents/MacOS/../Frameworks/libswiftCompatibilitySpan.dylib' (no such file), NSBundlePath=.../MyBundle.someBundle, NSLocalizedDescription=The bundle “MyBundle” couldn’t be loaded.} My setup: Xcode 26.2 macOS 26.2 (25C57) SDK (Built-in)

Each time I launch a Debug version of the app on iOS Simulator, I see the Launch Screen presented and then about a 30-second delay before the app is responsive and debug output appears in the console panel. Filed FB22345091

Hello! When launching/debugging on my iPad and iPhone I keep getting the following error: “Previous preparation error: Failed to find a DDI … Run ‘devicectl list preferredDDI’ …” I believe this was caused by a previously interrupted Xcode update around June due to low disk space, which may have left DeviceSupport/DDI/CoreDevice files incomplete. Even after finishing the update later, the error persists. I now use a new Mac with 4 TB of storage, but the issue still occurs. Since then I have unfortunately been blocked from testing or presenting my app on devices. It seems that only a new, fully completed Xcode update might resolve the problem. Tried so far: – Cleared caches (CoreDevice/Devices) – Reset trust on device and re-paired – Checked devicectl list preferredDDI I would really appreciate guidance, as at the moment I cannot present my app due to this blocking issue. Thank you very much for your support!

Hi everyone, I'm experiencing a persistent issue for months now where I'm unable to download the iOS 26 simulator Runtime. I've tried reinstalling Xcode and also Xcode Beta but same issue. iOS 26 Simulator is also not on developers download page, so manual installation is impossible. And sadly I can't compile any code without having iOS 26 simulator installed. Anyone able to get passed this? Hardware: M1 Pro OS: Tahoe 26.1 Heres the error Download failed.

It didn't happen with Xcode 16.2 that I used before, but after updating to 16.3, when I build the app, the following error is output to the console and the app doesn't run. dyld[2150]: Symbol not found: ___cxa_current_primary_exception Referenced from: <6B00A4F2-B208-3FDB-BA38-B7095AF0034A> /private/var/containers/Bundle/Application/B590DB18-9C66-4C9E-8330-104943419E60/Mubeat DEV.app/Mubeat DEV.debug.dylib Expected in: <7F51CB08-A0CA-386E-BB62-4B8BFB0CED9F> /usr/lib/libc++.1.dylib Symbol not found: ___cxa_current_primary_exception Referenced from: <6B00A4F2-B208-3FDB-BA38-B7095AF0034A> /private/var/containers/Bundle/Application/B590DB18-9C66-4C9E-8330-104943419E60/Mubeat DEV.app/Mubeat DEV.debug.dylib Expected in: <7F51CB08-A0CA-386E-BB62-4B8BFB0CED9F> /usr/lib/libc++.1.dylib dyld config: DYLD_LIBRARY_PATH=/usr/lib/system/introspection DYLD_INSERT_LIBRARIES=/usr/lib/libBacktraceRecording.dylib:/usr/lib/libMainThreadChecker.dylib:/usr/lib/libRPAC.dylib:/Developer/Library/PrivateFrameworks/DTDDISupport.framework/libViewDebuggerSupport.dylib After looking for another solution, I found a way to remove the -Objc option in Other Linker Flags, but this method only works on iOS 18.4 and doesn't work on other versions. Is there another solution?

Since upgrading my iPhone 13 Pro Max to iOS 26, apps have become nearly impossible to debug. The recent update to iOS 26.1 has made this even worse. Going from app start to a fully rendered & responding screen takes <1 second on a Debug build when no debugger is attached, but with the debugger attached I get these times (measured manually with a stopwatch): First render: <1 second without debugger 5 seconds on USB debugger 30 seconds on wireless debugger Data loaded from webserver and UI responding: <1 second without debugger 19 seconds on USB debugger 5 minutes on wireless debugger! Doing an online speed test reports 55 Mbps for the phone and 60 Mbps on the MacBook, so I doubt it's my WiFi. Having a debugger attached used to make minimal difference on iOS 18, but the performance has tanked completely since the last major release. What happened?
