Dear Friends, Is there a way to increase font size of xcode intelligence window? So the text i write, and the AI response. Why do i need this? I am using 4K monitor and i dont want to make Display setting bigger and lose all screen space.

I’m trying to use MCP servers with Xcode 26.3 Coding Intelligence (Codex agent). With a project-scoped config file at /.codex/config.toml, MCP servers are not reliably loaded. /.codex/config.toml Example: [mcp_servers.Notion] url = "https://mcp.notion.com/mcp" enabled = true [mcp_servers.XcodeBuildMCP] command = "/bin/zsh" args = ["-lc", "/opt/homebrew/bin/npx -y xcodebuildmcp@beta mcp"] enabled = true tool_timeout_sec = 10000 Expected: Xcode consistently loads MCP servers defined in /.codex/config.toml across restarts. Actual: Xcode often only exposes xcode-tools. In some sessions MCP servers appear, but after restarting Xcode they may disappear. The global file at ~/Library/Developer/Xcode/CodingAssistant/codex/config.toml also seems managed/rewritten by Xcode and isn’t reliable for custom MCP servers. Questions Is /.codex/config.toml the official/supported way to configure MCP servers for Codex in Xcode right now? Are there any requirements for Xcode to load it (e.g. workspace must be Trusted, open .xcworkspace vs .xcodeproj, full restart/force quit, etc.)? Is there any logging/diagnostics to understand why the MCP server is not starting or not being picked up?

Xcode 16 and 26 changes in painful way how the Tab key works during autocomplete. Previously, pressing Tab would extend the typed text up to the word match. For example, we have two classes: NSViewController and NSViewCoordinator BEFORE, typing: "NSV" + Tab used to complete to NSViewCo Now, in Xcode 26, pressing Tab just use the first suggestion. Stupidly. Especially when you want DispatchQueue and it gaves you DispatchSemaphore… That is very inconvenient because very often I want just see all possible cases with some prefix...without need of typing all prefix manually. How to restore the previous behavior? How to do autocomplete word-by-word?

I have configured Xcode 26.3RC to utilize Claude and Claude Agent. However, it does not seem to access Claude's config.json where I supply information for the MCP servers that I use with Claude. If I manually tell Xcode to look in the config file it finds the appropriate API keys, but that's not really a usable experience.

I started a project targeting macOS and used Storyboard app lifecycle. I also used Xcode Previews in this project. If I: Keep the entry point of the main storyboard to a window controller. (as default setup in macOS), Turn the Xcode window into full-screen, That window controller would pop up its window every time Xcode Previews refreshes. I tested in Xcode 26.3 RC and many versions before.

Hi there, I just re-install 26.2, but I got many issues regarding to SwiftUI's components. How can I fix it? Do I need download or install something else?

Are there workarounds for the following bugs in Xcode 16.3? I'm looking for workarounds instead of trying newer versions of Xcode because, from what I read, the Xcode release notes do not mention these issues being fixed. First bug: Resizing a NSSplitView in the UI Editor is buggy. When you try to use the divider, it just does not work as expected. In the case of a vertical split, the bottom view gets shrunk whatever you try to do. Second bug: When you type: (IBAction) in the source editor, you get the following buggy template (extra ')' on the right): - (IBAction)<#selector#>:(id)sender)

I've connected my Claude account into Coding Intelligence and working properly (opening a web browsing and connecting my account), but when I press Claude Agent it sayes that I have to login againt. When I press the Account login with Claude.ai account, a web browser is opened, but it never finished the flow and I have an infinite spinner. Apple M2 Pro with macOS 26.2 (25C56)

I have a framework, which depends on a library (GPGME) to do its actual encryption. As a consequence of using this external library, there are header files which have GPGME types in them... @interface E3Gpgme : NSObject ... /*****************************************************************************\ |* Call GPGME to sign \*****************************************************************************/ - (int) signWithMode:(gpgme_sig_mode_t)mode userId:(NSString *)signingKeyOrEmail srcStream:(E3Stream *)src dstStream:(E3Stream *)dst error:(NSError **)error; ... @end . This means the E3Gpgme class header file has to #import <gpgme.h> to get those type definitions. That is then proving problematic because the framework modularisation fails, with <e3gpgme.h> obviously not being a part of the framework, so the project refuses to build. I can see a few ways around this: Just don't run the modularisation check. That doesn't sound like a fantastic option import the GPGME headers (there's only 2) into the project and bundle them as if they were project ones. Again, not a great option, I don't expect GPGME to change its API but it runs the risk of there being a mismatch in future if the library code itself remains external. So what's the best-practice for requiring a dependency on a library, not a framework ? Is there a way to copy the library binary into a folder inside the framework folder and make sure you link with that ? Assuming that's the shared library it ought to still be ok for the LGPL licensing... Is there a better way ? I'm sure I'm not the first person to run into this :)

I've been trying to add my Github Account to Xcode, but even with my user name and access token, all I get is a spinning wheel. No error message, no feedback. Nothing. I'm going to do it from terminal but this seems just poor. Especially, since there's no feedback from XCode on what the problem is. Any help would be nice.

Hello! I'm using the new Xcode 26.3 RC and it's new MCP server: However, I am repeatedly prompted to give access to Codex (both the new macOS app and the CLI). And I'm seeing duplicates in the Xcode dropdown: It's pretty blocking in my workflow as I have to keep Allowing over and over again.

Is there a way to change the model to Opus it's using sonnet. I have a claude code max x2 subscription.

Hi! I have a Catalyst app that embeds command line utility. So the project has two targets: Catalyst target, this target depends on #2 and embeds it into its bundle. macOS target, the command line tool. Both targets have package dependency to the same package. I used this to embed the CMD tool. Everything builds, runs and works fine until I try to archive the project. Archiving stops early with such error: error: Multiple commands produce '/Users/kse2/Library/Developer/Xcode/DerivedData/PkgTest-clngkndczxoprpdlwefqqiqlryjt/Build/Intermediates.noindex/ArchiveIntermediates/PkgTest/IntermediateBuildFilesPath/UninstalledProducts/macosx/MacrosForSwift.o' note: Target 'MacrosForSwift' (project 'MacrosForSwift') has a command with output '/Users/kse2/Library/Developer/Xcode/DerivedData/PkgTest-clngkndczxoprpdlwefqqiqlryjt/Build/Intermediates.noindex/ArchiveIntermediates/PkgTest/IntermediateBuildFilesPath/UninstalledProducts/macosx/MacrosForSwift.o' note: Target 'MacrosForSwift' (project 'MacrosForSwift') has a command with output '/Users/kse2/Library/Developer/Xcode/DerivedData/PkgTest-clngkndczxoprpdlwefqqiqlryjt/Build/Intermediates.noindex/ArchiveIntermediates/PkgTest/IntermediateBuildFilesPath/UninstalledProducts/macosx/MacrosForSwift.o' What I have tried to fix archiving: Changing PkgTestCMD target to be on Catalyst/iOS instead of macOS. This works but I'm not sure how to properly run CMD tool with iOS SDK (if this correct at all): I need the main thread to be 'unblocked' and be active while background tasks exist. Adding an aux framework that act as container for the package. Doesn't work. Splitting targets into different projects, making workspace and cross-project reference. Doesn't work. My understanding is that archiving attempts to produce .o files for both Catalyst and macOS simultaneously, due to PkgTest being Catalyst and PkgTestCMD being macOS targets. How to archive such a project? Is there a way to separate archiving of CMD and main app? Maybe separate .o files into different directories. Simple building and running the project works, why archiving doesn't want to? I have a test project for the issue: PkgTest. main branch is the source project, DepFramework contains attempt #2, Workspace—#3. Thank you!

I've installed Xcode 26.3 on Sequoia 15.7.3 but I'm not seeing any of the AI options showing in Xcode that I see in usage/example videos. For example that AI icon in the top left hand corner isn't visible, and if I select Settings there is no Intelligence section, yet there is in all the demo videos. Why am I not seeing any of these new features?

I have the new Xcode 26.3 running on an Intel MBP macOS 26.2 I have clicked to download Codex in the Xcode settings, then under the Intelligence section I select Codex but where it says "ChatGPT Account" there is a spinner that never ends. I suspect it is meant to show a Sign In button. I don't see any documentation to suggest this shouldn't work on Intel, so what gives? My "ChatGPT in Xcode" section is successfully signed in, and i've tried signing that out.

I'm running Xcode 26.2 (17C52). After deleting all simulators and creating new ones, SwiftUI Preview stopped working. Xcode reports: “Simulator [D774B214-XXXX-XXXX-XXXX-XXXXXXXX8288] failed to boot and may have crashed.” However, when I list all available simulators using xcrun simctl list, there is no simulator with that identifier. It seems Xcode is still referencing a previously deleted simulator. I have tried: Deleting all simulators again Creating new simulators Restarting Xcode and the system But the issue persists and Preview still fails to launch. Has anyone encountered this issue or knows how to clear the cached simulator reference used by SwiftUI Preview?

I have got 26.3 running, signed in with calude max account and open ai plus account, but codex and claude agent "get " button is greyed out. I have apple intelligence turned on.. I can only use sonnet 4.5 inside xcode. anyone has an idea about whhy>?

I use Claude Code with AWS Bedrock models. I see that Xcode 26.3 has a way to add model providers but I don't see the URL or API key in use with Claude Code. Is it possible, or are the protocols different and I have to convince my company to pay for an Anthropic subscription
