iOS 26 Simulator - Extreme Memory Usage on M1 Pro
Hi everyone, Is anyone else seeing massive memory usage with the iOS 26 simulator? On my M1 Pro MacBook Pro (16GB RAM) running macOS 26, the simulator consumes all available memory, making my Mac extremely slow. This seems to be a memory leak. For comparison, the iOS 18.5 simulator runs perfectly fine and uses very little RAM. I've already tried restarting, but the issue persists. Has anyone found a workaround for this? Thanks.

Hi there. I'm super frustrated. My Apple Developer keeps telling me that I have no device to generate a provisioning profile. And it's not clear whether a device is registered. I have a Developed Account as a parent, but the macmini we are working on is registered to my son. Is this a poblem? Super frustrated as we simply want to archive his program to post for review. Can anyone help? We've been at this for days.

Trying to deploy WatchOS 9.6 to a watch that is on 10.6
I have an Apple Watch 4. (GPS). It's on version 10.6. I'm trying to deploy a basic app onto it (IOS 18) (WatchOS 9.6). I've set the targets in General for Watch App, Watch AppTest, Watch AppUITest. I still get an Apple Watches watchOS doesn't match App Watch app.app watch02 9.6 deployment target. Upgrade users Apple Watch watchOS version or lower app app.apps deployment target. What can I do to fix this?

visionOS Simulator: CloudKitWrapper not found
Hello, I'm working on a Unity game which uses Apple Arcade Cloudkit Unity plugin. Cloud save works on all platforms except visionOS. I tried to debug using visionOS 2.4 Simulator. When the game starts XCode display the following error: DllNotFoundException: Unable to load DLL 'CloudKitWrapper'. Tried the load the following dynamic libraries: Unable to load dynamic library '/CloudKitWrapper' because of 'Failed to open the requested dynamic library (0x06000000) dlerror() = dlopen(/CloudKitWrapper, 0x0005): tried: '/Users/seb/Library/Developer/Xcode/DerivedData/Unity-VisionOS-akwybgjotadlwrghmmfkhbhpuduf/Build/Products/Debug-xrsimulator/CloudKitWrapper' (no such file), '/Library/Developer/CoreSimulator/Volumes/xrOS_22O237/Library/Developer/CoreSimulator/Profiles/Runtimes/xrOS 2.4.simruntime/Contents/Resources/RuntimeRoot/usr/lib/system/introspection/CloudKitWrapper' (no such file), '/Library/Developer/CoreSimulator/Volumes/xrOS_22O237/Library/Developer/CoreSimulator/Profiles/Runtimes/xrOS 2.4.simruntime/Contents/Resources/RuntimeRoot/CloudKitWrapper' (no such file), '/CloudKitWrapper' (no such file) at Apple.CloudKit.CKContainer.CKContainer_Default () [0x00000] in <00000000000000000000000000000000>:0 at Apple.CloudKit.CKContainer.Default () [0x00000] in <00000000000000000000000000000000>:0 I opened up the "Debug-xrsimulator" and indeed there is no CloudKitWrapper. However, if I "show content" on the app and navigate to the "Frameworks" folder, all Apple Arcade plugins are here, including CloudKit. I guess the plugin is in the right location, but the code tries to load it from the wrong path.

I have a target that dynamically generates the modulemap when new headers are added. Is there a way to specify for the target that uses that modulemap to wait for this modulemap file?
I have two targets: Library and Generate-Library-Modulemap I use a modulemap to help bridge the Objective-C++ code to Swift. Generate-Library-Modulemap is set up to run only when new headers are added (this is done reliably through some trickery). This seems to work, but the problem is that if I add Generate-Library-Modulemap as a dependency of Library, it seems that by the time Library Generate-Library-Modulemap is run, the Library target has already loaded up an outdated modulemap file. The result is my first attempt to build after adding headers is that the framework fails, as even though the modulemap was generated, it was not attached to the framework. The second attempt succeeds as it reads the updated modulemap. Is there any way to force Xcode to run the Generate-Library-Modulemap step before starting on Library? Or perhaps attach the modulemap after the fact?

Is SFSymbol Customization officially valid as a method for using SVG in embedded widgets (lock-screen & watchOS)?
Is SFSymbol Customization officially valid as a method for using SVG in embedded widgets (lock-screen & watchOS)? I use this in UnitedPizzaHelper but wonder whether this is the prime cause why all widgets of this app gets missing on iOS devices? This issue only happened on at least 2 device in the recent 12 months (they are all on iOS 18, and one of them is running iOS 18.5... Rebooting device won't work.), and we currently have no clue how to troubleshoot this. Update: The guy running iOS 18.5 told me that the widgets are now discoverable after waiting for minutes. Seems that this is a random issue.

iOS 3.1.3 SDK
Hello!!! I want to do a little project for the original iPhone running iOS 3.1.3 and I don’t find the SDK for iOS 3.1.3. I’ve tried downloading Xcode 3.1.3 from the Apple Developer site, but during the installation process, the iPhone SDK doesn’t appear to be included. I also tested Xcode 3.2.2, but it doesn’t seem to have the iPhone OS 3.1.3 SDK either. Does anyone still have the iPhone OS 3.1.3 SDK available or know where I can find it? Thanks!! Edgar

New linker in Command Line Tools 16 not working with BLOCK DATA
We've encountered a critical issue with the new linker of CLT16 (version 16.1.0.0.1.1729049160) that prevents proper initialization of BLOCK DATA. BLOCK DATA are used to initialize global variables in our Fortran code, and its failure to initialize those variables leads to a program crash. This affects our community of more that thousand scientists worldwide. The current workaround is using the -ld_classic linker option. However, this option is deprecated and will be removed in a future release, as described in the Xcode release note. I've attached a minimal example that reproduces the problem using GNU gfortran with the following instructions (the attached main.f.txt and bd.f.txt need to be rename to main.f and bd.f, respectively): gfortran -c bd.f gfortran -c main.f ar rv libtest.a bd.o main.o gfortran -ld_classic -o good.x -L. libtest.a gfortran -o bad.x -L. libtest.a Running the two programs, one can see that the BLOCK DATA are not initialised without the option ld_classic, $ > ./good.x 3.7273802569289098 2.8083922366048202 $ > ./bad.x 0.0000000000000000 0.0000000000000000 We kindly request your attention to this matter and a prompt solution or alternative workaround. Best regards main.f.txt bd.f.txt part.txt

Price in a Xcode synced StoreKit configuration file is not updated when I change it on App Store Connect and always shows the starting price
Hello, I've noticed the prices of my products in my Xcode synced StoreKit configuration are not updated when I change the price in App Store Connect. I tried to manually sync the file, to remove and add it again to my project but old initial prices are still used. In the screenshot below, the price is currently $2.99 but the file still uses the initial price of $1.99. It makes testing a little bit painful because I'm never sure which product is being shown. Is this a bug? Is there a way to get the live production App Store prices be used instead of the starting prices? I filed a feedback for this: FB17798486 Regards, Axel

Sharing files from Finder to Simulator doesn't work
I'm trying to copy some files from the Finder on macOS 14 to several Simulator instances running iOS 16 and 17. When I right-click the file in the Finder, I can select Share > Simulator, then a share dialog pops up where I select the relevant Simulator and click on Send. According to this official help topic, the Files app should open allowing me to choose the destination, but instead nothing happens and the shared file is nothing to be seen. What's the issue?

Will Xcode be able to edit code directly?
I realized you needed to install OS Tahoe to get the models in Xcode and its working now, but the chat doesn't edit the code directly like Cursor. Is Xcode going to update to edit code directly? Would love to know. Thanks to anyone that answers.

Xcode opens multiple Terminal windows when running app
Whenever I run anything in xcode it opens an extra terminal that runs the program then exits immediately, but the app still runs through the normal xcode launch. It's not a huge issue but It's getting really annoying to realize I have like 7 windows of terminal open that are just doing nothing. Has anyone had this issue before?
