So yesterday I noticed that some of images in my app stopped appearing. All of them were placed in the on-demand resources, that is I've assigned tags to them. Up until yesterday they were working correctly but since then whenever I try to load the assets I get the error message saying: Error Domain=NSCocoaErrorDomain Code=4099 "Connection invalidated to streaming unzip service." My code for loading the asset is pretty straightforward and it was working perfectly fine before: let resourceRequest = NSBundleResourceRequest(tags: ["vinyl"]) defer { resourceRequest.endAccessingResources() } do { if await !resourceRequest.conditionallyBeginAccessingResources() { try await resourceRequest.beginAccessingResources() } } catch { assertionFailure("Vinyl image was not available, error: \(error)") } I'm obviously using it in asynchronous context, but the old method which used completion handler gives me the same error. Has anyone encountered this issue as well? I just updated my devices to iOS 15.5, maybe that update broke on-demand resources? Tested on Xcode 13.4, iOS 15.5

Hello, I'm unable to run any test cases in Xcode 16 with the iOS 18 simulator. Steps to Reproduce: Create a new iOS project in Xcode 16 using the default iOS app template with the testing option checked. Run any test or UI test case by clicking the "Play" icon in the Test navigator. Xcode gets stuck at the "Testing" state indefinitely. Environment: macOS 15 beta 8 Xcode 16 beta 6 iOS 18 beta 7 simulator

After upgrading to Xcode 16.0, I encountered the following error when building my project. It compiled successfully on Xcode 15 or Xcode 16 with -ld64. I am not sure how to resolve this issue and would appreciate any help. Here is the error message Assertion failed: ((ct == Atom::ContentType::objcConst) || (ct == Atom::ContentType::objcData) || (ct == Atom::ContentType::constData) || (ct == Atom::ContentType::constText)), function ObjCClassReadOnlyDataRef, file Atom.cpp, line 3022.

Using Xcode to build and deploy the app to my watch, this is what I get: “Waiting to reconnect to Apple Watch. Previous preparation error: Transport error." And then “Connecting to Apple Watch. Xcode will continue when the operation completes.” And these messages continue to switch between each other. Sometimes the watch to connect and the application starts, but more often a scenario occurs with endless reconnection. I'm using: MacOS 14.4.1 (MacBook Pro 2019; 1.4 GHz Quad-Core Intel Core i5), Xcode 15.3, Watch OS 10.2 (Apple Watch SE 1), iOS 17.1.1 (iPhone 15 Pro). Methods I tried: Connecting Macbook, iPhone and Watch to the same WIfi network; Disabling Watch (and IPhone) from the "Devices and Simulators" menu and setting up Watch (and IPhone) from the beginning. Any help?

We have an existing app in which we have implemented AppShortcuts. The snippet view works fine in iOS 17 while in iOS18 beta, it doesn't able to fetch color from xcassets. If we use system colours or UIColor it's working fine. Not working Color("progressColor") Working Color(uiColor: UIColor(named: "progressColor")!) Color.red Color(hex: "3881d3") // Note: We created Color extension to generate color from hex string.

Hi. Just update my MacBook Pro M1 with sequoia and Xcode and I got huge problem with preview on simply swiftui pages.

The new console in Xcode 15 is so terrible bad. Is it possible to get back the old console ?

When my mac is upgraded to 13.7, some shortcuts to Xcode are not available, such as command + left, command + right, command + Backspace

I've recently installed Xcode Version 15.0 (15A240d) and when I set a breakpoint it doesn't stop on the line of code where the breakpoint is set. Rather, it opens another window with the hex code. If I press F6 it doesn't highlight the next line of code, but I can see that it moved because the variables are changing. Is this a known bug? I have tried all the usual stuff like deleting derived data and restarting everything. I have even deleted com.apple.dt.Xcode directory in ~/Library/Caches. to set things back to the defaults. The only thing I haven't done yet is reinstall Xcode. Unfortunately, this is very bad timing as I need to get my app finished for the iOS17 and WatchOS 10 release.

After not happening to me for a few months, this issue has started hitting me again with currently %100 reproducability. If turn on VPN on my Mac then instantly the developer certificates within the keychain become untrusted. But that's not all, if VPN is then turned off the certificates do not revert to their trusted status but remain untrusted. The consequence of this is that if VPN is turned on and then a build is perform, it fails, and the only way to fix things is to delete the cert(s) from they keychain and re-install them. As a remote worker, having this happen several or even dozens of times a day is incredibly annoying and frustrating. This issue has been occurring for literally years, sometimes it occurs very often, others while its quiet for a while, and has spanned multiple versions of Xcode and Mac OS. So whatever the cause is its endemic. It doesn't just affect myself, but all the members in my development team. I'm currently using Xcode 14.1 RC 2 and Monterey but I've seen this issue occur with many versions of Xcode and Mac. (I'm using Cisco AnyConnect Secure Mobility Client). If the VPN is somehow interfering/affecting the connectivity aspect when an attempt is made by Xcode to validate the certificate, then why does it not rectify itself after turning off VPN? This is so so so so annoying. Can somebody please comment on why this happens and if there's a way to prevent it.

Hi, I'm setting up Xcode and after updating MacOS to 15.2 and Xcode to 16.2, I cannot download the Predictive Code Completion Model. I've done some research and I haven't found any solution, specially since most people suggest that it randomly fixed itself, which for me hasn't been the case. I've tried restarting my Mac, uninstalling and reinstalling Xcode multiple times, I've also reinstalled MacOS from Recovery and haven't found any success (I'm also not running Xcode inside a VM, as I've seen this can cause some problems in this case). This is the error that I receive when I attempt to download the model: And here are the details: The operation couldn’t be completed. (IDELanguageModelKit.IDEModelDownloadAdapter.(unknown context at $11eba9a90).DownloadError error 3.)

It would be nice for Apple to integrate chatgpt, Open AI, and create their own artificial intelligence. Siri is not equipped to answer questions that AI can. With increasing AI prevalence and usability, Apple is behind. Message to Apple: PLEASE UTILIZE AI TO MAKE APPLE THE BEST PLATFORM.

Happy to have a new MacBook Pro M4 now - the new machine was setup from time machine backup of my old MacBook Pro M1. Sadly Predictive Code Completion does not work on the new M4 (it was working great on the M1). Xcode shows as downloaded component: Predictive Code Completion Model [com.apple.fm.code.generate_small_v1.base: 500.1.81600.13.200772,0] [com.apple.fm.code.generate_safety_guardrail.base: 1.6.81619.13.200716,0] [com.apple.gm.safety_deny.input.code_intelligence.base: 32024010.20241007.171244.100.377,0] [com.apple.gm.safety_deny.output.code_intelligence.base: 32024010.20241007.171244.100.377,0] (Installed) Things I already tried: Removed and reinstalled Xcode 16 (also latest beta). Disabled/enabled Xcode Editor Settings for predictive code completion Many many reboots Removed Xcode cache Maybe the downloaded Model is somehow locked to the old machine? How can I remove, redownload or reinstall it again? Thank you very much. Tobias

Hi, I work on a iOS application which includes several local swift packages containing modularised code. Each of those local swift packages has a test target defined in their respective Package.swift, and when opening a local package folder standalone in Xcode, then the tests run without issues. However I would like in the main app's test plan to add the local package test targets and have them all run together when the main app's default test plan is run. Xcode allows me to select local package test targets within the main app's test plan (also within Test portion of the main app's scheme), however attempting to build for testing throws a "Module '…' was not compiled for testing". Any ideas on how to achieve this goal (run local package tests in conjunction with main app's tests) and avoid that error? Thanks Peter

Hi, After updating to Sequoia and the newest Xcode, I ran some Mac apps from Xcode. No code was changed, but suddenly, I'm getting: Can't find or decode reasons Failed to get or decode unavailable reasons Can't find or decode disabled use cases NSBundle file:///System/Library/PrivateFrameworks/MetalTools.framework/ principal class is nil because all fallbacks have failed One problem (I think) is that - Mac/System/Library/PrivateFrameworks/MetalTools.framework/MetalTools is an alias with no original that can be found. However, the MetalTools does exist in, for example, /Library/Developer/CommandLineTools/SDKs/MacOSX15.1.sdk/System/Library/PrivateFrameworks (and Mac ones). The app is very simple/ Any suggestions? I have an Intel Mac. Thank you! -Ashley
