I just upgraded to XCode15.3 and now all my projects with Assets are getting this compile error. I have tried removing DerivedData caches and rebooting but still get this error. Anyone else hit this problem with XCode 15.3? I was only Building for IOS 16.4 and 17.0.1 and Xcode 14.0 and 15.0 Build Error: Command CompileAssetCatalog failed with a nonzero exit code *** Terminating app due to uncaught exception 'IBPlatformToolFailureException', reason: 'The tool closed the connection (AssetCatalogSimulatorAgent) Execution Context: <IBSimulatorToolCoreSimulatorCLIExecutionContext: 0x600003d5d260 busyCount=0, Idle for 0.0 secs, lifeTime=26.3 secs>, device=IBSimDeviceTypeiPad3x (865E7291-E467-4E8D-B535-D64F43A57F15, iOS 17.4, Shutdown), idiom=<IBIPhoneIdiom: 0x6000028b8000>

I'm not sure if I'm changed an unknown-to-me setting somewhere, but since this morning, after profiling an app (metal, allocations, etc), every project I run/build on Xcode 15b3, either on simulator or on device, displays partially-alpha images blended to black, as if there was some problem in the process of compiling the PNGs (lack of premultiplying, color space, etc). If I open those same projects on Xcode 14, they are displayed everything as they should. Also, If I open them on other computers with Xcode 15b3 other than mine, it also works fine. And it was working fine for me this morning as well, but not anymore. I've tried uninstalling Xcode beta and the simulator a few times, cleaning folders and preferences, hoping it was some setting I changed by mistake with some hotkey, but no luck so far. I'll attach two pictures, one from Xcode 14, and the other one from Xcode 15b3, hoping it's some silly thing I'm missing. xc15b3: xc14:

XCode 15.3 What should I do? I can not edit GeneratedAssetSymbols.swift.

Currently, I try to test the ImageTrackingProvider with the Apple Vision Pro. I started with some basic code: import RealityKit import ARKit @MainActor class ARKitViewModel: ObservableObject{ private let session = ARKitSession() private let imageTracking = ImageTrackingProvider(referenceImages: ReferenceImage.loadReferenceImages(inGroupNamed: "AR")) func runSession() async { do{ try await session.run([imageTracking]) } catch{ print(error) } } func processUpdates() async { for await _ in imageTracking.anchorUpdates{ print("test") } } } I only have one picture in the AR folder. I added the size an I have no error messages in the AR folder. As I am trying to run the application with the vision Pro, I receive following error: ar_image_tracking_provider_t <0x28398f1e0>: Failed to load reference image <ARReferenceImage: 0x28368f120 name="IMG_1640" physicalSize=(1.350, 2.149)> with error: Failed to add reference image. It finds the image, but there seems to be a problem with the loading. I tried the jpeg and the png format. I do not understand why it fails to load the ReferenceImage. I use Xcode Version 15.3 beta 3

Is it possible to make generated asset symbols (ASSETCATALOG_COMPILER_GENERATE_ASSET_SYMBOLS and/or ASSETCATALOG_COMPILER_GENERATE_SWIFT_ASSET_SYMBOL_EXTENSIONS) public so that they can be used by targets that import the framework defining them?

I created a distinct icon set for visionOS, and specified its name in build settings. This is a Designed for iPad app. When I run it in the simulator, only the existing app icon shows. Is this supported for existing iPad apps, or am I missing something? There are no warnings in the asset catalog for this.

I have an AppleTV app which I released in 2016. I've updated it and released a new version every year without much hassle. This year, with tvOS 17.2, the layered app icon isn't working right. This is a two-layer image made with PNGs. When it's selected, it looks right and the layers move correctly: But when it's not selected, the background layer disappears: Screenshots are from the simulator but it also happens on the device. It's inconsistent; sometimes it's the front layer that disappears. Occasionally both layers work, but I can't tell why. I've spent a day trying everything. Very frustrated. The icon previews correctly in Xcode and in Parallax Viewer. The image sizes are correct: 400 x 240 for Small, 800 x 480 for Small@2x, 1280 x 768 for Large. The back layer is a non-transparent PNG. I tried adding a Large@2x set. Didn't help. Originally I had a three-layer image with no middle layer PNG. I deleted the empty middle layer, but that didn't help. All the PNG files are from GnuIMP. Same color space, even. I was using the filenames tvicon-back-s.png and tvicon-back-s@2x.png. I tried taking out the @ sign in case that was confusing Xcode. (It never has before, but I am flailing here.) Anybody have any clues? If it's an Apple bug and there's nothing I can do, I'm going to just push the release button and hope it fixes itself someday.

We want to provide an alternate app icon in our bundle specifically for testing with an App Store test treatment (A/B test). What I'm unclear about is whether we then need to enable users to choose from the available app icons, since there are now multiple. I have seen reports of apps being rejected because they didn't offer this feature when multiple alternate icon sets were bundled. We do NOT want to allow users to select an app icon. Also, is it permissible to have a different icon for the App Store than what is used for the device app-launcher? I believe the guidance here is that all sizes of the icon should have the same content (just resized), but our marketing people want to test a different icon for the app-store specifically. Is there guidance on this somewhere that I haven't found?

Related APIs: +[UIImage imageNamed:] +[UIImage imageNamed:inBundle:compatibleWithTraitCollection:] When there is only a color set with the name (no image set provided), reading the image with the above-mentioned APIs throws an exception: 2023-12-19 19:30:34.008701+0800 ***[57410:578064] *** Assertion failure in -[_UIImageCGImageContent initWithCGImageSource:CGImage:scale:], _UIImageContent.m:666 2023-12-19 19:30:34.031207+0800 ***[57410:578064] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Need an imageRef' Even when wrapped in a try/catch block, it still crashes due to a lock issue after calling the related API twice.

It's a bug of UIKit?

Xcode generates symbols for image and color assets now (which is super nice!). We noticed an issue when generating code symbols for our image assets. We have an image named inputContour and one named inputContourColor. Xcode was not able to generate a symbol for inputContourColor and instead produced the following warning: #warning("The \"inputContourColor\" image asset name resolves to the symbol \"inputContour\" which already exists. Try renaming the asset.") It turns out that the generator automatically removes the color suffix when creating the code symbol. For color assets, this probably make sense (so tealColor would become just teal), but this should not be applied to image resources.

"I am developing a project called 'Avatar Creator.' In the HeadSelectionView, BodySelectionView, and LegSelectionView screens, the user will choose one of the images available there. In the final FinalSelectionView screen, I want to display the images the user selected, but I'm facing a problem.

It appears I can't add a WebP image as an Image Set in an Asset Catalog. Is that correct? As a workaround, I added the WebP image as a Data Set. I'm then loading it as a CGImage with the following code: guard let asset = NSDataAsset(name: imageName), let imageSource = CGImageSourceCreateWithData(asset.data as CFData, nil), let image = CGImageSourceCreateImageAtIndex(imageSource, 0, nil) else { return nil } // Use image Is it fine to store and load WebP images in this way? If not, then what's best practice?

CoreUI is sending warning messages to the Xcode console when creating a UIImage from an image file with Mac idiom from the asset catalog, while running on Catalyst. My target is set to support running on Mac Catalyst with Optimize for Mac enabled (the latter seems to be the most important part). Loading the image into a UIImage with the designated initializer and presenting it in a UIImageView produces the following console messages: 2023-02-15 10:53:18.014394+0100 CatalystImageConsoleMessage[64253:8834791] [framework] CoreUI: _Bool CUIValidateIdiomSubtypes(NSInteger, NSUInteger *) got a device subtype '32401' that it match with idiom '7':mac.

Assuming subtype should be 0 instead. Working with more than a handful of images from the catalog makes the Xcode console output borderline unreadable because of these messages. The console doesn't have an option to filter out messages (and in general we consider it bad practice to ignore messages on the console). Tested on Xcode 14.2 with macOS 13.2. You can find a sample project at https://github.com/tamasjager/CatalystImageConsoleMessage.

Hi, If I change the AppIcon in Xcode's Assets.xcassets, and rerun my app, the image used in the dock and app switcher does not update. If I "Clean Build Folder", and re-run, then it updates. This is annoying when I keep tweaking the colors in the icon and want to see how they look. A full rebuild takes a while, because I have a few Swift Package dependencies. Anyone know a trick to get the AppIcon to stop caching (or whatever it's doing)? I tried killall Dock and killall Finder, but that didn't help. (macOS 11.2.3) Rob

I want to access to a small number of Markdown text files. It looks like the asset catalog feature "Folder with Namespace" might do well, as I could store these small files in a folder that the asset catalog contains. How would I go about getting the string contents of a particular file if I know its name?

I am using DeepAR and PixelSDK in my project and these both SDK's has same file name "cameraVieewController" when I try to run application I get this error. Is their any solution to resolve this naming issue?

I have created enum and UI Color Extension which returns Semantic UIColors created in Assets Catalog in iOS app. But is there any way that I can create UIColor Programatically that supports Dark and Light Mode using RGBA etc? Ans avoid using Asset Catalog.
