“Xcode”

iOS 12 is no longer supported for debugging with Xcode 26. There is no supported path for using iOS 12 in on-device development workflows in Xcode 26.

Per the Xcode 26.3 Release Notes, Xcode 26.3 supports on-device debugging in iOS 15 and later. iOS 12 is no longer supported target for running your app with the debugger attached.

The SDKs for all of Apple's platforms are included in the main Xcode XIP image. By SDK here, I mean the textual files for the API interfaces, like header files and other supporting content. You can see them all if you peak inside the Xcode bundle under Xcode.app/Contents/Developer/Platforms/.platform/Developer/SDKs. What you need to download isn't the SDK, it's the platform support components, which includes the simulator. While you always have the textual SDKs, you can't run a build without installing the platform support components, as they are used during the build process. So while you aren't downloading installing the textual part of the SDK content, the large extra component download enables builds using that SDK. You found the right documentation article, and you want a command like this: xcodebuild -downloadPlatform iOS -exportPath ~/Downloads That will give you a DMG file, which you can then also install through the command line over night in your data center with: xcodebuild -impor

I've just received a notification that this issue has been addressed in Xcode 26.3, which introduced a setting to enable individual width for navigators/inspectors in window tabs. It's great that the Xcode team listens to our feedback.

@DTS Engineer: Thanks for chiming in, Ed. I've just received a notification that this issue has been addressed in Xcode 26.3, which introduced a setting to enable individual width for navigators/inspectors in window tabs. It's great that the Xcode team listens to our feedback. P.S. My next rant that I'm about to post will be regarding the bug FB19249805 to highlight another productivity downgrade in Xcode 26: the inability to open files in new window tabs, which destroys workflows that have been established for many years.

This keeps happening in Xcode cloud watchOS simulator 26.2 (Apple Watch Series 10 (46mm) (watchOS 26.2) simulator) and I cannot finish my test CI/CD pipelines. How can I solve?

How do I go about troubleshooting this? So, the place to start is actually with this log message: eventually ends with provider entitlements check failed The log message is the final, generic, error message printed by IOUserService when the entitlement check process fails. A few things to understand about what this tells you about what HASN'T gone wrong: Basic entitlement validation happens outside the kernel well before this point. So getting to this point means that your DEXT is at least somewhat coherently signed, even if it doesn't actually work. IOKit passive matching happens at the same time as entitlement checking (just before actually), so this message means that either your passive match failed or your entitlement configuration was wrong. So, the next step here is to actually take a closer look at this logging: In the logs I see the matching log entry for my driver, and it goes through some setup that mentions my driver and some entries that do not. Focusing on the entitlement checking side, each IOK

I'm seeing a similar issue as well. Seems like the Foundation model is just not available for iPhone and iPad simulators anymore. To test it out I created a simple playground (similar to https://developer.apple.com/events/resources/code-along-205/) and just used basic code: import FoundationModels import Playgrounds #Playground { // Create a new session with the language model. let session = LanguageModelSession() // Asynchronously generate a response from a text prompt. let response = try await session.respond(to: Generate a 3-day itinerary to Paris.) } For macOS simulator it works, but for iPhone and iPad simulators it gives either error: Apple Intelligence is not enabled. The operation couldn’t be completed. (FoundationModels.LanguageModelSession.GenerationError error -1.) I've tried Xcode 26.2. 26.3, 26.4 beta 1 & 2 versions. iPhone Simulators 26.2, 26.3 and 26.4 beta and none of them works. This is on a M4 Macbook pro I also have an old M1 Macbook pro I haven't used since December and just t

i have the same issue, i have a claude account paid, with xcode 26.3 but im having infinite loading after finishing the SSO. The infinite loop appears in xcode

Another strange thing is that when dragging the crash report to the Xcode dock icon, the Xcode console logs this error: User Command: command script import -s lldb.macosx.crashlog User Command: crashlog --interactive --skip-status --no-parallel-image-loading ~/crash.ips Resolved symbols for 0A35BC69-660D-3BC0-8AB4-3FA8D922EECB /usr/lib/libobjc-trampolines.dylib...
