In Xcode 26.3 and 26.4, when I use Xcode's built-in git functionality to do a "pull" or "fetch", Xcode presents a dialog saying it's performing the operation, but it never completes. The dialog remains on screen with a spinner. My remote repos are stored on a Mac mini on my local network and I access them via SSH. The git command line works fine, as does the tool Git Tower. I've filed this as FB22091014. Has anyone else seen this, and if so, found a solution?

Hi, In Xcode 26.2, editor tabs adapt their width to the number of pinned tabs: In Xcode 26.3, editor tabs have a minimal width, after which the row of tabs becomes horizontally scrollable: Notice how less tabs are visible at a time on Xcode 26.3 (second image). Yet, there is enough horizontal space to accommodate more, as shown on Xcode 26.2 (first image). This is a UX regression. How can I revert back to 26.2 tab sizing behavior? Thank you.

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.

I keep getting a fails to open page message when I try to sign in using my Claude ai Pro account. The request was for an http url instead of an https url.

As stated in the title, my device is M4 macmini, running macOS 26, with Xcode version 26.1. The error message is ": retrying debugserver without secure proxy due to error: Error Domain=com.apple.dtdevicekit Code=811 UserInfo={NSUnderlyingError=0xc42b07930 {Error Domain=com.apple.dt.MobileDeviceErrorDomain Code=-402653150 UserInfo={MobileDeviceErrorCode=, com.apple.dtdevicekit.stacktrace=, DVTRadarComponentKey=261622, NSLocalizedDescription=}}, NSLocalizedRecoverySuggestion=Please check your connection to your device., DVTRadarComponentKey=261622, NSLocalizedDescription=}, the official documentation does state that debugging is supported for devices running at least iOS 15. However, my 2019 MacBook Pro, with macOS 15.7.2 and Xcode 26.1 installed, can debug iOS 12 devices normally. The product manager has asked me to identify the issue, but I am at a loss. If anyone can provide a solution or confirm that support for iOS 12 is no longer available, we would be very grateful. Additionally, iOS 13 devices can all be debugged normally

I have made an app using Xcode 26.3 Release Candidate 2 for my Apple Watch that runs successfully on the simulator. Xcode comes with the IoS 26.2 and WatchOS SDK 26.2. However, when I do try to connect to my device that have IoS 26.3 and watchOS 26.3, I see a succesful connection to my iPhone but I see the the world symbol and wheel keeps trying to connect on my Apple Watch. I also tried Xcode 26.4 beta 2 with no luck. I reviewed the WatchOS Release Notes: The watchOS 26.2 SDK provides support to develop watchOS apps for Apple Watch devices running watchOS 26.3. The SDK comes bundled with Xcode 26.2, available from the Mac App Store. I also tried Xcode 26.2 but no luck. Any suggestions?

I am looking to optimize my AI-assisted workflow within Xcode. Previously, my process was inefficient: Manually selecting and copying code snippets from Xcode into Gemini. Asking a specific question (e.g., "Modify this to show an alertError message box"). Copying the result back into Xcode. I attempted to switch to the new native Intelligence feature in Xcode to streamline this, but I found significant shortcomings: Latency: The response time is noticeably slow. Much slower than asking directly on Gemini 3 Pro. Lack of Context: The AI often fails to grasp the full project context. For example, it frequently claims it cannot see the code for ScannerView even though it is part of the project. I often have to prompt it multiple times before it finally "finds" the file. Is Xcode's Intelligence feature actually production-ready yet? If not, what tools do you recommend that integrate well with iOS development? To be clear, I am not looking for "vibe coding." I have a clear grasp of the problem and the high-level solution. My goal is to delegate the low-level implementation to the AI. I need a tool that has full project context from the start, eliminating the need to manually copy-paste snippets into a chat window.

I am using official MCP SDK. According to official guide, Servers MUST provide structured results that conform to this schema. https://modelcontextprotocol.io/specification/draft/server/tools#output-schema I could see output schema defined, but result have no structured content. Current output schema: { name: "XcodeListWindows", title: "List Windows", description: "Lists the current Xcode windows and their workspace information", inputSchema: { type: "object", properties: { }, required: [ ], }, outputSchema: { type: "object", properties: { message: { description: "Description of all open Xcode windows", type: "string", }, }, required: [ "message", ], }, } Current response: { "result": { "content": [ { type: "text", text: "{\"message\":\"* tabIdentifier: windowtab1, workspacePath: \\xxx\\n* tabIdentifier: windowtab2, workspacePath: \\xxx\\n\"}", }, ] } } Expected: { "result": { "content": [ { type: "text", text: "{\"message\":\"* tabIdentifier: windowtab1, workspacePath: \\xxx\\n* tabIdentifier: windowtab2, workspacePath: \\xxx\\n\"}", }, ], "structuredContent": { "message": "* tabIdentifier: windowtab1, workspacePath: \\xxx\\n* tabIdentifier: windowtab2, workspacePath: \\xxx\\n", } } }

I have a UI Test that is trying to drive a stepper. When run as iPad app, the tree has: Button, 0x10ce7f860, {{492.0, 98.5}, {47.0, 32.0}}, identifier: 'GraphDataViewNumBinsStepper-Decrement', label: 'Number of bins: 4, Decrement' Button, 0x10ce802a0, {{539.0, 98.5}, {47.0, 32.0}}, identifier: 'GraphDataViewNumBinsStepper-Increment', label: 'Number of bins: 4, Increment' When run a Mac app, the tree has: StaticText, 0x7fcf5380d670, {{1575.2, 530.0}, {109.0, 16.0}}, identifier: 'GraphDataViewNumBinsStepperText', value: Number of bins: 4 Stepper, 0x7fcf5380d7b0, {{1691.5, 527.0}, {15.0, 22.0}}, identifier: 'GraphDataViewNumBinsStepper', value: 0 IncrementArrow, 0x7fcf5380e420, {{1692.5, 528.0}, {13.0, 10.0}}, Disabled DecrementArrow, 0x7fcf5380e560, {{1692.5, 538.0}, {13.0, 10.0}}, Disabled Is this an expected situation or might I be building for an inappropriate version of MacOS or iPadOS?

I have two apps; one is a subset of functionality of the other. The smaller app has about 170 Swift files. The larger app has these files plus about 120 more. So I would expect the larger app to take around twice as long to build. Instead, the smaller app takes less than a minute to build while the larger app takes over 13 minutes to build; to be exact, it takes 15.3 times longer. While reviewing the build report, I noticed that the smaller app compiles the Swift files in batches, with each batch taking around 10 seconds, but with up to 17 batches running at once. In contrast, the larger app compiles all 290 Swift files in one giant batch, so apparently there is no multithreading of the Swift compilation (see screen shots below). The difference in the number of batches the smaller app compiles at once roughly corresponds to the difference in overall build time. Is there a build setting I can change to make the larger app compile Swift files in multiple smaller batches as the smaller app is doing? I checked SWIFT_COMPILATION_MODE and it's the same in both apps (Incremental for debugging and Whole Module for release) but I don't know what other settings I should check.

Mac Pro 2019, Tahoe 26.3, Xcode 26.2 Mac Mini 2023 M2, Tahoe 26.3, Xcode 26.2 On Mac Pro 2019 the app is only Intel while on Mac Mini 2023 M2 it is ARM64 only. Both have Standard Architectures (Apple Silicon, Intel). Both have Build Active Architecture Only is set to No (Debug + Release). Happen for default new projet macOS -> App and Obj-C, Xib. No change to defaults setting except uncheck "Automaticaly manage signing" and "Signing Certificate" set to "Sign to Run Locally" HOWEVER On Mac Pro 2019, BigSur 11.7.10, Xcode 14.10 the application is build Universal ! Why cannot build universal with Tahoe 26.3, Xcode 26.2 ? Can I submit a Mac applcation to App Store Connect with BigSur 11.7.10, Xcode 14.10 ? What are the minimal version of Mac Os and Xcode to submit a Mac applcation to App Store Connect ?

... and I managed to fix most issues coming out, but for a specific issue in an class adopting a protocol; basically it is a support class to be used by the view controller and so I wanted to keep it in background, so I created a new actor and I wanted to use it for this protocol and adopting classes. Yet I came out with a host of errors I have no idea about how to cope with: :

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??? Please restore the normal, pre-26 behavior of the Navigators pane. That is, the Navigators pane should remain open or closed as PER INDIVIDUAL WINDOW TAB, not globally. Thank you for your attention to this important issue!

Hi, I’m a paid Apple Developer Program member and I’m seeing an entitlement issuance issue with ShazamKit. ShazamKit is enabled for my App ID (com.tomharris.dnbidfinder) in Certificates, Identifiers & Profiles. However, every iOS Development provisioning profile I generate does not include the entitlement: com.apple.developer.shazamkit verified this by decoding the downloaded .mobileprovision file: security cms -D -i .mobileprovision | /usr/libexec/PlistBuddy -c "Print :Entitlements" /dev/stdin The entitlement dictionary does not contain the ShazamKit key. Because of this: • The signed .app does not contain the Shazam entitlement • SHSession.match(signature) fails on device • I receive ShazamKit runtime error 201 / 212 I’ve already: • Toggled ShazamKit off and back on for the App ID • Created new provisioning profiles • Created a brand new App ID to test • Refreshed profiles in Xcode The portal UI shows ShazamKit as enabled, but the entitlement is not being issued into provisioning profiles. Has anyone experienced this before? Is there an additional approval step required for ShazamKit, or could this be a backend entitlement propagation issue? Thanks.

In the Coding Intelligence feature introduced in Xcode 26, when I send a message using ChatGPT in Xcode, the message “Your request couldn't be completed. Networking error.” appears and I’m unable to use the feature. I suspect the issue may be related to the VPN or network proxy connected to my Mac and am attempting to investigate. However, Xcode does not display any specific error details, nor does it provide a way to view them, which makes a detailed investigation difficult. Next to the error message, there is a feedback button rather than a stethoscope (🩺) button, and the feedback window does not provide access to the underlying error information. Is there a way to view the detailed network error logs generated by ChatGPT in Xcode? (I am using Xcode 26.0.1.)
