Recently I noticed that although my drive showed ~800Gb of usage, the folders within totally to around ~600Gb (and yes I was including hidden 'dot' files/folders. After some inspection I found that there are a whole set of Disk Media Images, that appear to be related to XCode simulators.

Hello! I'm new to xcode and am developing an iOS app. I hit the following error when build my app: MY_SHA no identity found Command CodeSign failed with a nonzero exit code I have generated my certificate through xcode. I can see the Certificate and the private key in Keychain -> login. But it's not that private key is under the Certificate. They are listed in parallel. The certificate appears in Certificate tab but not in My Certificate Tab. Would that matter? security find-certificate -a -Z | grep -A1 "Apple Development" Gives me the certificate. But security find-identity -v -p codesigning give 0 valid identity found. Could you help me figure out what could be the reason for this? I've been stuck for several days now. Thank you so much!

I'm trying to download the iOS 26.2 simulator, but it fails both in Xcode and via the command line. When I run: xcodebuild -downloadPlatform iOS -buildVersion 26.2 -exportPath ~/Downloads It returns: iOS 26.2 is not available for download. I would like to know: Why iOS 26.2 simulator cannot be downloaded at the moment. Whether iOS 26.2 simulator is still available, or if it has been removed or replaced. How to properly get and install the iOS 26.2 simulator. Any official explanation or solution would be greatly appreciated. Thank you!

In my tabview i set a safeAreaBar topPanel, under i have contentview. That ignore safeArea.top so feed go under. What is the best Way to have a the first post in content appear under (under the bottom) if the safeareabar. I use list with foreach. Do we measure the height or is it some smart tips?

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

I have three rogue iOS simulators, how to correctly delete them and reclaim the disk space? These img files are costing me 18gb of storage.

Hi everyone, I want to avoid the iOS 26 Liquid Glass effect in my app’s UI. While researching, I found the following possible solution: Steps: Go to Info.plist Add the key: UIDesignRequiresCompatibility Type: Boolean Value: YES I have a few questions about this approach: According to the Apple Developer website, this seems to be a temporary solution. How long will this continue to work, and what would be the recommended long-term solution? Which iOS versions does this support (both older and upcoming versions)? If this method is not recommended, is there another way to disable or avoid the glass effect across the entire app without making major UI changes? Any guidance or suggestions would be greatly appreciated. Thank you!

Hello everyone, I’m facing an issue with my app submission being stuck in “Waiting for Review.” I initially submitted my app on 21 February and waited until 27 February, but the review process did not start and there were no updates. On 27 February, I contacted Apple Support regarding this issue, but I did not receive any response. Since there was still no progress, on 4 March I removed the app from review and resubmitted it again, but it is still showing “Waiting for Review.” This delay is affecting my operations, so I would really appreciate any guidance or help if someone has experienced a similar situation. App ID: 6741708449 Thank you.

Dear Xcode Team, Please consider adding an option to position the Coding Assistant on the right side of the editor. Currently, when the assistant panel is open, it makes it difficult to access the Project Navigator at the same time. Having the ability to move the Coding Assistant to the right side would allow developers to keep the Project Navigator visible while interacting with the assistant, improving workflow and efficiency. Thank you

Can't able to run the Create ML for training and I upgraded to MacOS 26.3 beta and I have tried older and newer

I have Xcode 26.1.1 (installed on a Mac Mini with Sequoia 15.7.2), which was installed from the Universal .xip file available from the Apple Developer site. This file is 2.7Gb. When Xcode is run, there is a menu item at Settings -> Components, and the top section "Platform Support" includes an option to "Get" the iOS SDK, which is an additional 10.3Gb download.[1][2] I would like to either use command-line tools to obtain this iOS SDK component, or find where the downloaded package or its contents are installed on this Mac. This Apple Documentation some examples of using command-line tools to download components for Xcode. However, there is no specific documentation on how to separately download the iOS SDK. It seems that if possible, it could be done with "xcodebuild -downloadComponent", however I have tried a number of likely component names (ios, ios_sdk, ios26.1, ios_sdk26.1, iphoneos, iphoneos_sdk, iphoneos_sdk26.1), and none are valid. Does anyone know either where the SDK download can be found, or how to download it using command-line tools? Background: I require this as I am managing a fleet of Mac Minis located in a data centre (used for iOS/Android builds), and Internet access is restricted - any action requiring Internet access needs the Mac to be removed from the machine room racks and taken to a build room, then connected to a mobile hotspot or similar. This access is slow, and the above 10.3Gb download can take over an hour. If I can download the SDK separately, I can distribute it to all of the Macs over the internal network overnight, in advance of visiting the DC for upgrade tasks. [1] Various web sites say that the iOS SDK is "bundled with" Xcode. However, if that's the case a) how is a 10.3Gb download somehow included in a 2.7Gb file? And b) why do I still need to "Get" this component after installing Xcode from the 2.7Gb file? [2] Note that I am not looking for the iOS Simulator, I have already downloaded the iOS 26.1 version of this. I am specifically looking for the iOS SDK as listed under "Platform Support" in the Xcode menu described above.

I have been getting the following error intermittently (once it happens, then its consistent) when I try to build my app Showing Recent Errors Only Unable to resolve build file: BuildFile<b11862f281fd8c8287d499b4f0922a9c61c95323d2196ba877ed344a02baffbb> (The workspace has a reference to a missing target with GUID '0c7e19da3805e0a412c717704d4549fc25560b498add930cbef9623bd9afb53a') There have been no changes to my project (git status is clean). I have tried cleaning DerivedData as well, but it did not help. How am I supposed to figure out from the GUID what is it that xcode is trying to find?

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?

Development environment: MacBook pro Apple M1 macOS Tahoe 26.2 (25C56) Xcode 26.x iPhone 6 Plus / iOS 12.4.4 Exception description: After I upgraded to Xcode 26, my iPhone 6 Plus had a system version of 12.4.4. I was unable to perform real-device debugging, whether for existing projects or new ones. The error message from Xcode was as follows: Could not launch “xxx” Domain: IDEDebugSessionErrorDomain Code: 3 Failure Reason: Cannot launch '/private/var/containers/Bundle/Application/A44062C1-32F5-4346-B13C-FC3F39EAF7A1/xxx.app': Unspecified Even though I have already added device support for the iOS 12.4 Has Xcode 26 stopped supporting the debugging of any devices running iOS 12 system?

When I create an archive file and attempt to upload the app using the "Distribute App" button, the upload fails with the error "Automatic signing cannot update bundle identifier...". (The detailed message is below.) When creating an archive file in Xcode, I unchecked "Automatically Manage Signing" and proceeded with the archive. The message says "Font Enumeration," but other apps with the same option enabled upload successfully. Therefore, I believe the "Font Enumeration" option is not the issue. I tried creating a new provisioning file, but it still doesn't work. I deleted all DerivedData files from my Mac storage, restarted Xcode, and tried again, but it still doesn't work. This keeps happening only for certain targets (specific apps) in Xcode. Does anyone know how to fix this? Xcode is the latest version. Message: Automatic signing cannot update bundle identifier "com.xxxxxx.xxxxxx". Automatic signing cannot update your registered bundle identifier to enable Font Enumeration. Update your bundle identifier on https://developer.apple.com/account and then try again.

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?

After exerting a custom model with nms=True. In Xcode, the outputs show as: confidence: MultiArray (0 × 5) coordinates: MultiArray (0 × 4) I want to set fixed shapes (e.g., 100 × 5, 100 × 4), but Xcode does not allow editing—the shape fields are locked. The model graph shows both outputs come directly from a NonMaximumSuppression layer. Is it possible to set fixed output dimensions for NMS outputs in CoreML?

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.
