Does Xcode 26 still support creating pull requests and/or viewing comments from GitHub pull requests associated with the current branch? This used to be possible, but I cannot get it to work with the current version of Xcode (26.0.1). The "Create Pull Request" menu item takes me to github.com directly, instead of presenting a nice UI menu; hence I'm wondering.

Environment: Xcode 26.3 RC macOS 26.3 (25D125) (Apple Silicon / arm64) Setup: Xcode > Settings > Intelligence > Claude Agent: Signed In (account status shows "Signed In") Model: Default Steps to reproduce: Open a new chat in Xcode's Coding Assistant Select "Claude Agent" from the agent dropdown (instead of "Claude Sonnet 4.5") Send any message (e.g. "HI") Expected result: Claude Agent responds normally. Actual result: The message is sent but immediately returns the error: "Your request couldn't be completed." 🚩I have an active Claude Code subscription with remaining usage. Running claude in Terminal works perfectly, confirming the subscription and quota are valid.

Hi. In my app a need do change launch screen. During development sometime in when I install new version of app over old version sometimes I see old launch screen. Is it possible that this situation will happen on production when I will publish app to App Store? Is Launch screen somehow cached?

Currently it's Sonnet 4.5. I know that 4.6 is out.

Will I be able to download and run Xcode 26.3 on a new MacBook Air with an M5 chip? If yes, what memory size is recommended? 16, 24 or 32 GB ?

It doesn't show any files, only warning or errors for me. Same behavior with @

I've recently updated to Xcode 26.3 and I can't download any iOS Simulator Runtime from 26.2 to 18.0, every download gives me: Download failed.

I saw some reddit posts where they suggested to check out VPNs, host files and other stuff but everything was okay, also I can reach apple cdns etc. I also tried using Xcode beta 26.4 and going back to 26.2 but still the same problem. Anyone has a solution?

My project uses about 10 local packages. When Xcode determins its dependencies graph it includes project Foo (a package) and project Foo_Foo (???). This is a no op for normal builds, but causes the Foo package to be linked twice for test builds which then fail due to duplicate symbols. Nowhere in my repository is Foo_Foo defined or reference. Nowhere in the .xcodeproj/ folder is there mention of Foo_Foo. What am I doing wrong?

I have a group of XCUItest suites that were designed to run in parallel on simulators. They run fine in xcode 16.2, but when I try to run them in Xcode 26 they run fine the first time, but on the second time I get an error that the simulator cannot be found: "No matching device (62621AD4-C8D6-4A1B-B511-79236113FD94) ". This UDID seems to be from one of the clones that were spawned on the previous test run.

Here's the text of FB22001359 I've just submitted: Xcode 26 changed the behavior of the Inspectors pane (which hopefully is a bug and not an intended behavior). Now, if I close (or open) the Inspectors pane in a window tab, it closes (or opens) the Inspectors pane in ALL tabs. This is insanely horrible, unproductive, time-wasting behavior that breaks workflows that has been established for many years. By way of example: In a window tab that contains a .xib, I always want the Inspectors pane to be open. While in the window tabs that contain code files, I want the Inspectors pane to be closed. (Sometimes I do open it in certain window tabs, when needed). Before Xcode 26, the Inspectors pane was open or closed in each individual tab as the user desired. Now, if I close the Inspectors pane in one window tab, the pane closes EVERYWHERE. Thus when, for example, I go to a .xib window tab, I have to open the Inspectors pane AGAIN. But then when I go back to a code window tab, I have to CLOSE the Inspectors pane there (because it became open globally). And have to do this endlessly every day. WHY??? Please restore the normal, pre-26 behavior of the Inspectors pane. That is, the Inspectors pane should remain open or closed as PER INDIVIDUAL WINDOW TAB, not globally. Thank you for your attention to this important issue!

Here's the text of FB22008758 I've just submitted: Xcode 26 changed the behavior of the Navigators pane (which hopefully is a bug and not an intended behavior). in Xcode 26, if I close (or open) the Navigators pane in a window tab, it closes (or opens) the Navigators pane in ALL window tabs. This is insanely horrible, unproductive, time-wasting behavior that breaks workflows that has been established for many years (I've been using Xcode since 2006). By way of example: In a window tab that contains a .xib, I prefer the Navigators pane to be closed. While in all other window tabs (that contain code files and other items), I want the Navigators pane to be always displayed. Before Xcode 26, the Navigators pane was open or closed in each individual window tab as the user desired. But in Xcode 26, if I close the Navigators pane in one window tab, the pane closes EVERYWHERE. Thus when, for example, I go to a .xib window tab, I have to close the Navigators pane AGAIN. But then when I go back to a code window tab, I have to OPEN the Navigators pane there (because it became closed globally). And have to do this endlessly every day. WHY???

Steps to reproduce: Open Xcode 26.3 → Settings → Intelligence → Claude sign-in Click the sign-in button — spinner begins, never completes An email the arrives with a magic link. The magic link opened a browser page which displayed a 6-digit verification code with instructions reading "enter this verification code where you first tried to sign in" — i.e. back in Xcode. However, Xcode was showing only an endless spinner with no code entry field anywhere in the UI. This is the core bug. I did since manage to complete authentication sign-in through a second browser verification field that eventually appeared after about 10 minutes and did get signed in, but the Claude Intelligence agent still returns "Your request could not be completed" even after successful sign-in and a full Xcode restart. Prior to this bug starting at 10 am on February 19 I had been using the intelligence agent successfully for about a week. Anthropic did have some sort of event on their system around February 18/19 so maybe this has been a result of that. I have notified Anthropic support and Apple Feedback Assistant. Does anybody have a workaround until either anthropic or Apple get back to me?

Hi, I recently updated my Mac to macOS Sequoia 15.7.2, and then updated my Xcode packages right afterward. However, when I try to open Xcode, I receive the message: “You can’t open the application because it is being updated.” I contacted Apple Developer Support (software) by phone and went through their troubleshooting steps, but the issue persists. They confirmed that everything appears fine on their end. In System Settings, both macOS and Xcode show as fully up to date. However, when I manually check in the App Store, it says Xcode needs to be updated. When I press Update, I get the following error: “Xcode could not be installed. Please try again later.” I’m fairly new to Xcode, but it seems there may be an incomplete update or verification loop preventing the installation from finishing properly. Could you please advise on how to resolve this so I can open Xcode again?

Hello, I've been searching online for ways to remedy this issue for the past 3 days and this is my last resort. The Issue Build on device fails to connect to the device. The prompt will permanently be stuck loading in that screen. Finder is able to connect to the device, just that Xcode is unable to. Xcode does prompt for passcode on the device, and I have entered it accordingly. I note that i AM on VPN, but even disabling VPN and turning off Wifi does not fix the issue. This was working until several days ago. Not sure what the issue is. Fixes Attempted Tried with a different cable, and USB ports Tried with different devices (multiple devices both iPad and iPhone has the same issue) Turn Off and On developer mode on devices. Clear Trusted Computers on devices. Updating both devices to the latest iOS version. Quitting Xcode Clearing derived cache Restarting Macbook Updating to the latest iOS version on Macbook Reinstalling Xcode toggling signing certificates I was trying other fixes like "pkill usbmuxd", but since I am on corporate hardware, i will be required to escalate it if i require sudo permissions. Is anyone able to provide a concrete solution or explanation why this happens?

Hi there, I am trying to use the agentic coding with the new Xcode update, however the "Intelligence" tab is not coming up on the left hand side of my Xcode settings. I've ensured I have macOS greater than 26, I've got Apple Intelligence and Siri enabled. I've shut down and restarted Xcode and my computer. Still, the option is not available. Can anyone help?
