I am using DuckDB as an external dependency in my project. The package is basically a Swift wrapper around C++ code. If I run my app in Debug mode, then the performance of the library is an order of magnitude slower than when I run it in Release mode. In Release mode it is really fast, but compilation times are too slow. I am a complete beginner to Xcode's build system and was wondering if there was any way to have the best of both worlds? For example, by compiling my SwiftUI code without optimizations but having it linked to a static and optimized version of the library.

As predictive code completion is natively included in Xcode, are we allowed to use it for the Swift Student Challenge?

I'm trying to retrieve the overall memory peak of a process. I've looked into retrieving it through task_vm_info struct defined in task_info.h By logging the members of the struct, it seems neither resident_size_peak, internal_peak or ledger_phys_footprint_peak is matching what the peak memory value that's being detected by xcode instrument. Can anyone point me to the correct way to retrieve that peak value? Is it the summation of some of the fields in task_vm_info` or is there a more complicated algorithm involved in deriving that value?

I have an app on the App Store for many years enabling users to post text into clouds in augmented reality. Yet last week abruptly upon installing the app on the iPhone the screen started going totally dark and a list of little comprehensible logs came up of the kind: ARSCNCompositor <0x300ad0e00>: ARSCNCompositor (0, 0) initialization failed. Matting is not set up properly. many times, then RWorldTrackingTechnique <0x106235180>: Unable to update pose [PredictorFailure] for timestamp 870.392108 ARWorldTrackingTechnique <0x106235180>: Unable to predict pose [1] for timestamp 870.392108 again several times and then: ARWorldTrackingTechnique <0x106235180>: SLAM error callback: Error Domain=Slam Error Code=7 "Non fatal error occurred due to significant drop in a IMU data" UserInfo={NSDescription=Non fatal error occurred due to significant drop in a IMU data, NSLocalizedFailureReason=SlamEngineNodeGroup Failure: IMU issue: gyro data stream verification failed [Significant data drop]. Failed on timestamp: 870.413247, Last known timestamp: 865.350198, Delta: 5.063049, System timestamp: 870.415781, Delta between system and frame: 0.002534. } and then again the pose issues several times. I hoped the new beta version would have solved the issue, but it was not the case. Unfortunately I do not know if that depends on the beta version or some other issue, given the app may be not installed on the Mac simulator.

I have downloaded Xcode 16.1 and after the first run it downloaded 18.1 simulator and then watchOS 11.1 Simulator. Then I suppose it detected my watch 7 with OS 8.1 and wanted to download symbols for it but then it failed with 403 error. Any way to do it some other way?

Hi all. I have encountered an issue in which I failed to build the app on Xcode. It says "Provisioning profile doesn't match the entitlements file's values for the com.apple.developer.team-identifier and application-identifier entitlements". But I have checked these two values, they are exactly the same as expected.

we run into this error please help --> Provisioning profile failed qualification Profile doesn't support Tap to Pay on Iphone ---> Provisioning profile failed qualification Profile doesn't include the com.apple.developer.proximity-reader.payment.acceptance entitlement

I'm trying to run an xctest bundle, built for catalyst, with xcrun. i.e. xcrun xctest path_to_my_test.xctest It fails, complaining that: The bundle "MyBundle" couldn't be loaded because it is damaged or missing necessary resources. Try reinstalling the bundle.....but incompatible platform (have 'MacCatalyst', need 'macOS') So it seems like because I'm not executing it in a sim it wants the bundle to be a macOS bundle. But I would have thought it would be possible to run a Mac Catalyst target directly on a macOS host the same as a native macOS test target. Is this not possible?

I'm getting consistent errors in Xcode 16.1 while trying to implement type-safe CIFilter instances as documented on the page at https://developer.apple.com/documentation/coreimage/cifilter. After pasting in the example code on that page for a "FalseColor" filter into a simple test project's ContentView, I get an error explaining that: "Type 'CIFilter' has no member 'falseColor'". Same thing with pasting in the example code at https://developer.apple.com/documentation/coreimage/cifilter/3228278-boxblur, and other examples. I have imported CoreImage, so that shouldn't be the issue. Am I doing something wrong, or is this functionality just broken? I have had success creating filters with the string-based API, but access to a type-safe API would obviously be preferable, so any suggestions are greatly appreciated.

I am using Mac Mini M2 with Sequoia 15.1 OS with Virtual Machine (Virtualization.Framework) with same OS.

There was a failure decoding response: (HTTP 401, 60 bytes) The data couldn’t be read because it isn’t in the correct format. Please fix that I can't see information like teams and so on

I'm trying to create the app icon for my visionOS app. The Assets catalog already contains AppIcon for iOS and I've added another AppIcon for visionOS. If I only add the Back layer of the visionOS icon, compiling succeeds despite there being an error The visionOS App Icon "AppIcon" must have at least 2 layers with applicable content. Although it has 3 layers, only 1 has applicable content. As soon as I add one of the other two layers, say the Front layer, compiling fails, but this time Xcode only shows a generic compiler error Command CompileAssetCatalogVariant emitted errors but did not return a nonzero exit code to indicate failure If I click that message, a long build log opens containing among other things: 2024-10-31 11:28:15.258 AssetCatalogSimulatorAgent[66919:1456355] -[TDTextureRawRenditionSpec _createImageRefWithURL:andDocument:format:] Texture image asset file:///~/Documents/apps/myApp/xcode/iOS/Assets.xcassets/AppIcon.solidimagestack/Back.solidimagestacklayer/Content.imageset/icon_layer3.heic not in one of supported formats ... libc++abi: terminating due to uncaught exception of type NSException Command CompileAssetCatalogVariant failed with a nonzero exit code What is the problem? I filed FB15642844.

If I define some values in an .xcconfig then I can use those to supply a value to an element within Info.plist, but if I try to do the same for a .plist with any other name then it doesn't work. Is this some sort of hard-coded constraint? (I can't move the elements out of the custom .plist into Info.plist as its being read by a 3rd party framework)

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

Dear Support Team, I constantly get a 401 unauthorised error, when I try to add my Developer account in Xcode while running a virutalised macOS using https://developer.apple.com/documentation/virtualization. So I can't use signing, entitlements, etc when building within a virutalised macOS. The error shown is below: There was a failure decoding response: (HTTP 401, 60 bytes) The data couldn’t be read because it isn’t in the correct format. I've found probably the same issue here https://developer.apple.com/forums/thread/759877 Unfortunately, I can't find any updates. Are you aware of this problem? Are there any planned fixes in upcoming macOS updates? 15.0 (24A335) Version 16.1 (16B40) Apple M1 Pro, 16 GB Ram Best regards, Evgenii
