Hi I am seeing an LLDB crash in the RPC server. I have tried to update and restart everything but I am still seeing this problem. I have break points setup around code that is invoked when a WKWebView based code is being loaded. There does not seem to be a specific state the debugger crashes in and it is hard to isolate any changes in the code base. A collegue also managed to reproduce the crash. Ever so often it will be successful on then to crash on a subsequent run. This has happened on Device and simulator. We suspect that maybe a library change may of caused debug symbols to be missing or something like that. What options to I have to debug the root cause of this crash?

We are seeing some unexpected differences in the appearance of our App when run on a real iPhone (iOS 26 final release) compared to iOS 26 simulators in Xcode 26. Our App run in the iOS 26 simulators (for any iPhone model we try) shows more Liquid Glass effects / artifacts than when run on real devices: In Light Mode buttons in the top Navigation Bar have a surrounding bubble on the simulators. (See attached screen shots.) A SwiftUI Picker element shows more elaborate Liquid Glass transition effects. Also: some UI elements are positioned differently on the simulators compared to a real device. (See the search field under the header on the attached screen shots.) The simulators have in the past been very faithful to the real devices. Is there a setting that controls this behaviour? For the simulator I have: macOS 26.0 Xcode Version 26.0 (17A324) Simulator is iPhone 15 / iOS 26.0 (23A343) Real device is: iPhone 16e iOS 26.0 (23A341)

I'm working on an AppIcon selector and would like to do something like UIImage(named: "AppIcon-Alternate") to present the icon for the user to choose using the new IconComposer icons. I've done a fair bit of research on this and it looks like this used to be possible (prior to .icon) with workarounds that were later 'fixed' / removed (appending 60x60 to the icon name). The only 'solution' seems to be bundling the exported images into the app itself but this seems like a terrible idea as it massively bloats the app. Assuming we export from the new IconComposer tool and want to include dark mode that's roughly 3MB per icon which is absolutely shocking bloat and so a terrible solution. Looking into the app the Assets.car actually generates png files for these alternate icons. These are in the json as "MultiSized Image" assets. Interestingly using UIImage(named: is actually attempting to load these but fails to resolve an kCSIElementSignature. Also the OS alert when switching alternate icon shows a preview of the icon so this must be privately possible and using Asset Catalog Tinkerer I'm able to see these pngs. This feels like broken API; I'd guess the new icon format is not correctly generating the entry in the Asset.car to link the generated pngs for usage with UIImage(named:) API. Does anyone have pointers for this? This feels like a developer API afterthought or bug but is it intentional? Edit: I've submitted feedback for this FB20341182.

XCode has failed countless times in updates, and every time it fails, it has to be downloaded again. By 2025, the App Store will still be so foolish as not to have download caching function. Previously, there was a separate installation package for XCode, but now the official website does not provide a separate address?

EXC_BAD_ACCESS (SIGKILL (Code Signature Invalid)) Crash Report

Installed xCode 26 RC. other Components: Predictive Code Completion Model is installed. Go to Settings and Intelligence should be under Apple Accounts. However, it is not. How do I get Intelligence turned on?

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.

Hello. I am using Xcode 26.0 (17A324) with an iPhone 13 mini with iOS 26.0 (23A341). Due the network policies where my computer is at this moment, I am not able to prepare this iPhone to debug applications with Xcode over WiFi. There is no way to connect my computer to this iPhone over Wifi, just using the USB cable. My question is: how to debug applications in this situation, only using the USB cable? Every time I try to prepare this iPhone to be a available device to Xcode I received this error: " Browsing on the local area network for iPhone (2), which has previously reported preparation errors. Ensure the device is unlocked and attached with a cable or associated with the same local area network as this Mac. The device must be opted into Developer Mode to connect wirelessly.

We are working on an internal enterprise iOS application which we need to host a pretty complex web page inside. We have been reading regarding the WKWebView and how it performs inside of iOS shell, but there is no real data on what are the limitation of the WKWebView in terms of memory for the hosted Web Page. Let's say we could measure our iOS app before the WKWebView is launched and after it is launched. We see that the memory consumption of the web page loaded into WKWebView is X mb. How would we know that iOS would allow an app with such webpage loaded into WKWebView and won't terminate the app which the web page is loaded. Is there any documentation regarding on what is the maximum allowed memory for the web page which is hosted inside of WKWebView? And another question, for the Enterprise Developer Program are there any ways to increase the limit of the memory a specific iOS app is allowed to consume before it is terminated from iOS device due to low memory warning from iOS?

I have recently restarted an old code base. The app uses App Groups to communicate with network and endpoint system extensions. For some reason, in Xcode > Target > Signing & Capabilities the app groups are showing up with red text. I feel the red signifies a problem, but I cannot figure out what it is. The app compiles and runs, but I feel there is problem that I am missing. Any idea why App Group names would be displayed in red?

Yes I know x code only works with macs but my computer recently took water damage and I don’t have money for another Mac so I’m just going to buy a windows for work but if there’s any way to run Xcode with windows I’d like to know please. Thanks in advance

Hey guys, I updated to macOS Tahoe and after that I tried installing Xcode 26, but I always get an error message saying it can’t complete the installation, both through the App Store and via direct download from Apple’s website. Is anyone else having this same issue?

Using Xcode 26 (17A324) I can no longer bring up the Object Library with the '+' at the top right because it is not there. I can use Cmd-Shft-L but how do I make the '+' appear again. The '+' you can see in this screenshot is just for Tabs and Editor pains

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.

I'm from Bangladesh . I am a flutter developer . for my app i need to create bundle id . but there is no option for verify my account with Bangladeshi address

I want to use a ci_script to change the CI_BUILD_NUMBER to a new value. But in XCODE CLOUD there seems to be no programmatic way to change it?

Is there a way to use CFBundleVersion instead of CI_BUILD_NUMBER from XCode Cloud's workflow on Web ? We would like to have control over the major and minor version numbers of the build from the workflow.

I have Xcode 26 on one Mac, but LM Studio running on another. LM Studio does not have an api key so I have provided "dummy-api-key" but whenever I try to connect, it gives the error "Models could not be fetched with the provided account details" I have the IP and port (1234) of LM Study The server in LM Studio is running. Has anyone got this to work? And if so, what details did you enter?

Lately, I keep getting this warning when closing Xcode asking if I want to save the changes. Strangely enough, I have never received this before. I looked to see if I could disable and enable autosave. Unfortunately I have not found anything. Does anyone have any tips?
