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>

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

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?

"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.

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?

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.

My app uses various PNG images for parts of its UI. In Sonoma these images are rendered all blurred. It looks like I'm putting a 10 or 20px gaussian blur on it, which of course I am not. In prior macOS versions they have rendered just fine. Occasionally some user action in the app will cause a part of one or two images to render sharply, but then it quickly reverts to the blur. I have added the PNGs to the app as image set assets, providing 1x and 2x versions for light and dark modes respectively (so four images each). I'm loading them using NSImage(named: ), and in most cases putting them into an NSImageView. I also use one of them as a patternImage: if let image = NSImage(named: "RackFrame") { let color = NSColor.init(patternImage: image) color.setFill() dirtyRect.fill() } Both methods result in the same issue. Any thoughts on what's going on would be gratefully received!

The Assets.car file in Archive and thus in exported .ipa file has significantly increased when archived in Xcode 15 compared to Xcode 14.3.1. For example, the Assets.car file size in the archive made in Xcode 14.3.1 is 125 MB, but in the archive made in Xcode 15 from completely the same project size is 200 MB. Assets have many images as PNG and PDF. What has changed in Xcode 15 for building Assets.car file and how the size can be reduced? Use SVG instead of PDF (and PNG?)? Thanks

Are sub-folders and their content supposed to be excluded from the release archive? Our CI is failing due to the IncludedFile having a dependency on the ExcludedFile from the screenshot. If we move it out of the Subfolder, the archive succeeds. Xcode Version 14.3.1

I am rendering a png image with an alpha channel from XCAssets in a UIImageView. The rendering occurs as it should in iOS 16 / Xcode 14, but the image is distorted in iOS 17 beta / Xcode 15 beta. I am not sure why, but the distortion is very apparent. I have attached below the original PNG, as well a screenshot comparing the incorrect iOS 17 / Xcode 15 beta behavior vs the iOS 16 / Xcode 14 desired behavior. Comparision: Original image:
