When developing app for iPad most of them are fixed portrait because of the nature of the app. IOS26 now ignores this settings because windows can be resized and windowed so breaking this fixed option, very annoying. Even if you maximise the window it still rotates.

For difficult reasons I won’t get into, I ended up manually downloading the latest iOS 26 simulator runtime. I now have a file named 78756498-8AB4-4E5A-986C-7AA435758657.aar copied to my Mac. How do I get this archive installed so Xcode 26 recognizes it as a proper simulator runtime component? All searching I‘ve done for manually installing simulators references dmg files and older versions of Xcode. There’s no mention of aar files. When I tried the command: sudo xcrun simctl runtime add ./78756498-8AB4-4E5A-986C-7AA435758657.aar I get the result: An error was encountered processing the command (domain=NSPOSIXErrorDomain, code=22): Error while creating AEA backend Invalid argument I tried to use Archive Utility to open the file but that just says it is unable to expand the file. I even tried renaming the file with a dmg extension and then tried mounting the file and I get the same “AEA backend” error. My Mac doesn’t have sufficient Internet access to let me download and install this normally through Xcode. I need to find a way to get this file installed manually.

Upgrading from XCode 16 to 26, I redownloaded the simulators, and now I'm having a blank simulator choice that I cannot seem to do anything about. When pressing the + at the bottom, Xcode stops responding. Things I've tried; Reinstalling Xcode (after removing /devlopers) Changing minimum deployments (to any version) Changing iOS Deployment Target (to any iOS version) Any clues on what I'm missing here? It was working on XCode 16 yesterday. Images https://preview.redd.it/blank-simulators-xcode-26-v0-g7h0rkdt1npf1.png https://preview.redd.it/blank-simulators-xcode-26-v0-zze2zsuv1npf1.png

I have four apps currently deployed on the App Store. One of these apps crashes on launch when running on iOS 26, but functions as expected on iOS 18 and earlier versions. I am seeking to understand what changes in iOS 26 might be causing this issue. When running the app in debug mode on devices with iOS 26 using Xcode 16.1, the app crashes. The crash log references libobjc-trampolines.dylib, suggesting a potential issue with the Objective-C runtime. Has anyone else encountered a similar issue? AGX: AGX: agxa_device_template.hpp:1467:setupCompiler: *** FATAL: driver shader binary file not found in (null) for extension g15p!!! D [yHZ]: added warning: [MEDIUM]: SW04: A debugger is attached to the App. D [ProbeCallbacks]: [IXGUARD] debugger detected objc[1461]: couldn't dlopen libobjc-trampolines.dylib: dlopen(/usr/lib/libobjc-trampolines.dylib, 0x0106): tried: '/usr/lib/system/introspection/libobjc-trampolines.dylib' (no such file, not in dyld cache), '/usr/lib/libobjc-trampolines.dylib' (no such file), '/private/preboot/Cryptexes/OS/usr/lib/libobjc-trampolines.dylib' (open() failed with errno=24), '/usr/lib/libobjc-trampolines.dylib' (no such file, not in dyld cache) What steps can I take to resolve this crash? Thank you for your assistance.

The other day the XCode account had some error that I so that I decided to log out and in again. But when trying to log in to my apple account I get this "Bad URL" with the description "Try signing in again or contact Apple Developer Support to resolve account access". This only happens on the XCode on my work computer. I can log in to XCode on other computers with the same account. This happens only on this computer and with any account that I try to log in to. Obviously there is some cache file somewhere that I need to delete. But I am not finding it.

So I asked the integrated AI a question and the answer was just some hallucination. Now that's nothing new. But the AI then proceeded to apply those hallucinated changes to my code base. Luckily I had no uncommited changes and could use git to revert those multi file changes. But it could have easily been different. So what did I do wrong? Did I click something? Pressed the wrong key? Don't want to happen this again and possibly destroy work.

I have Xcode 16.4 and want to upgrade to Xcode26 on a MacBookPro with Intel and macOS 26.0. However I keep getting the error message (in German), that the download of the App is not possible, Xcode could not be installed and I should try later. I tried to restart the Mac, close all Apps etc. I tried it meanwhile several times, but still no success. Any Idea what I could try or do to solve the problem? Thx in advance

The code is shown as follows. Once the tabViewBottomAccessory is enabled, the tabViewSidebarBottomBar disappears. TabView { Text("tab a") .tabItem { Image(systemName: "a.square") Text("Tab A") } .ignoresSafeArea(edges: [.all]) Text("tab b") .tabItem { Image(systemName: "b.square") Text("Tab B") } .ignoresSafeArea(edges: [.all]) } //.tabViewBottomAccessory { // Text("tabViewBottomAccessory") //} .tabBarMinimizeBehavior(.onScrollDown) .tabViewStyle(.sidebarAdaptable) .tabViewSidebarBottomBar { Text("tabViewSidebarBottomBar") }

I am scheduling critical user notifications with a custom sound. This worked for years both on devices and in the simulator. Since Xcode 26 it crashes in simulator. Example let content = UNMutableNotificationContent() content.title = "Critical" content.body = "Example" content.sound = UNNotificationSound.criticalSoundNamed(UNNotificationSoundName("notification.aiff"), withAudioVolume: 0.5) content.interruptionLevel = .critical let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 10, repeats: false) let request = UNNotificationRequest(identifier: "exampleCriticalNotification", content: content, trigger: trigger) UNUserNotificationCenter.current().add(request) It seems that simpler variants such as just content.interuptionLevel = .critical or just content.sound = UNNotificationSound.defaultCritical also crash. I assume that critical notifications is a small niche use case but i still hope this gets fixed. This is filed as FB20272392 with a full crash log.

I recently updated to macOS sequoia 15.6 Afterward, I updated to Xcode 26 The project I've been running for the last couple years no longer compiles on existing simulators and doesn't build to a physical device. I'm getting an error I'm not familiar with and have no idea how to directly resolve it: The specific error is 'Command SwiftGeneratePch failed with a nonzero exit code' Looking up this issue via Google, there wasn't really a lot of information on this particular build failure. Most suggestions were to change the location of the Derived Data folder (Xcode -> File -> Project Settings -> update location of derived data from default to relative) This was one of the only actionable solutions I found online but this doesn't fully address the issue for me, it just creates a new issue: "Command PhaseScriptExecution failed with a nonzero exit code" I feel like with enough digging around I should be able to find a solution to the "PhaseScriptExecution" issue; there seems to be a decent amount of information online about that particular problem. I would prefer if I could solve the original 'SwiftGeneratePch" failure without needing to address other issues, though. Is this possible?

I've instilled Tahoe and Xcode 26(17A324) and the combination is virtually unusable, particularly the latter I'm no longer able to build projects reliably. My workflow is completely disrupted by a spinning beach ball so just a warning that you might want to delay until taking the plunge as I should have done. Fortunately, I have a back sequoia machine I can use instead.

Hi everyone - I'm seeing an issue specifically on iOS26 where we instantiate a few storyboard items programmatically and pull their restoration identifier. On iOS26, these identifiers are null and cause a crash, but the assignments are on the storyboard and there has been no change to that logic. On iOS 18, for example, there is no crash and the identifiers are pulled properly. Anybody else seeing this?

Tab titles are truncated and unreadable when many tabs are open. The old scrolling behaviour in Xcode 16.4 was better. Xcode 26.0 Xcode 16.4

Touch Bar items: Jump to destination and Ident missing and Customise Touch Bar unavailable in Xcode 26.0 (17A324).

Hello all, I saw the update of xcode26 on the App store, and from the compatibility information, I saw that xcode26 supports macos15.6 and higher. I'm not sure if xcode26 can be installed on macos 15. I can't install xcode26 on macOS 15.7.

Error: Unable to install “My App” Failed to install embedded profile for com.apple.myapp : 0xe800801a (This provisioning profile does not have a valid signature (or it has a valid, but untrusted signature).) I've tried almost everything, but I keep getting the same message on a Mac Mini M1 and several physical iPhones (11 and 16, both Pro). On a MacBook Air (Sequoia 15.7) with the same account, the same profiles work without any problems; and on simulators with iOS 26, it also works without any problems. This clearly tells us that the provisioning profile is not the problem, which is what the message mentions. It obviously has to do with the 26 update. P.S All of this worked fine before installing iOS, macOS, and Xcode 26.

Totally noob programmer here, forgive me if this is a basic user error. But there seems to be a mismatch between my apple id identifier and my team identifier. It has been automatically configured, and worked until today, but while trying to run a new app on my iphone i all of a sudden got "Failed to install embedded profile for com.kylland.formattingtest : 0xe800801a (This provisioning profile does not have a valid signature (or it has a valid, but untrusted signature).)". Now it does not work on any apps. Went through what chatgpt had to give me, trying to log in and out, made sure automatic signing is enabled and tried to delete the key from keychain. Still comes up with two different keys.

The iPad Pro on iPadOS 26 now operates on the same class of silicon as Apple’s entry-level Macs. It ships with M-series processors, 8GB of unified memory, support for multiple resizable windows, a menu bar, and proper external display connections. The device already has the foundation required for professional software development. The only gap is the absence of Xcode. Making the full version of Xcode available on iPad Pro would not take away from the Mac. Large and resource-intensive projects will still require the power of MacBook Pro and Mac Studio. What it would do is allow smaller and mid-sized projects to be developed directly on iPad Pro, which the hardware is fully capable of handling. That dynamic is complementary, not cannibalizing. Developers would continue to buy Macs but would also buy iPad Pros for portability and flexibility. The revenue upside is clear. Lowering the entry barrier means more developers enrolling in the Apple Developer Program at $99 per year, creating predictable recurring subscription income. A wider developer base leads to more apps reaching the App Store. Even if many are small, Apple benefits from every transaction through its revenue share. This strengthens the services business, which already delivers the company’s highest margins. There is also a direct hardware impact. Once Xcode is available, iPad Pro will be recognized as a legitimate professional development device. That drives more unit sales of a high-margin product line and increases attachment rates for accessories like the Magic Keyboard, Apple Pencil, and external monitors. Instead of eroding Mac sales, the effect is expansion. Developers will own both devices. The case is straightforward. The hardware is ready. The operating system is ready. Enabling full Xcode on iPad Pro would expand the developer funnel, grow recurring subscription revenue, increase App Store volume, and boost high-margin hardware and accessory sales. It is a decision that benefits developers, strengthens the ecosystem, and maximizes profit.
