Overview

why do I need to set the font of an image of an SF symbol to get the effect to work? This should be a bug, it's bad behavior. Xcode 16.1 iOS 18.1, so frustrating. for example: this works Image(systemName: "arrow.trianglehead.2.clockwise.rotate.90.circle.fill") .symbolEffect(.rotate, options: .repeat(.continuous), value: isActive) .font(.largeTitle) .onAppear() { isActive = true } but this does not animate, which makes no sense Image(systemName: "arrow.trianglehead.2.clockwise.rotate.90.circle.fill") .symbolEffect(.rotate, options: .repeat(.continuous), value: isActive) .onAppear() { isActive = true } its the same if you use a simple setup and different font size, and whether font is before or after the symbol effect Image(systemName: "arrow.trianglehead.2.clockwise.rotate.90.circle.fill") .font(.headline) // only works if this line is here .symbolEffect(.rotate, options: .repeat(.continuous))

Hello everyone! I've encountered an issue related to SwiftUI and StoreKit. Please take a look at the SwiftUI code snippet below: import SwiftUI struct ContentView: View { var body: some View { NavigationStack { List { NavigationLink { Page1() } label: { Text("Go to Page 1") } } } } } struct Page1: View { @Environment(\.dismiss) private var dismiss @State private var string: String = "" var body: some View { List { NavigationLink { List { Page2(string: $string) .simpleValue(4) } } label: { Text("Tap this button will freeze the app") } } .navigationTitle("Page 1") } } struct Page2: View { @Binding var string: String? init(string: Binding<String>) { self._string = Binding(string) } var body: some View { Text("Page 2") } } extension EnvironmentValues { @Entry var simpleValue: Int = 3 } extension View { func simpleValue(_ value: Int) -> some View { self.environment(\.simpleValue, value) } } This view runs normally until the following symbol is referenced anywhere in the project: import StoreKit extension View { func notEvenUsed() -> some View { self.manageSubscriptionsSheet(isPresented: .constant(false)) } } It seems that once the project links the View.manageSubscriptionsSheet(isPresented:) method, regardless of whether it's actually used, it causes the above SwiftUI view to freeze. Steps to Reproduce: Clone the repository: https://github.com/gongzhang/StrangeFreeze Open it in Xcode 16 and run on iOS 17-18.1 Navigate to the second page and tap the button, causing the app to freeze. Remove manageSubscriptionsSheet(...), then everything will work fine

The app gets stuck after login on an iOS 18 device. It works in Xcode, but the simulator shows the following console error: IntegrationApp(769,0x1f0094c00) malloc: xzm: failed to initialize deferred reclamation buffer (46).

Hi, I heve a problem with an visionOS app and I couldn't find a solution. I have 3D carousel with cards and when I use the drag gesture and I drag to the left I want the carousel to rotate clockwise and when I drag to the right I want the carousel to rotate counter clockwise. My problem is when I rotate my body more than 90 degrees to the left or to the right the drag gesture changes it's value and the carousel rotates in the opposite direction? Do you know how can I maintain the right sense taking into account that the user can rotate his body? I've tried to take the user orientation with device tracking and check if rotation on Y axis is greater than 90 degrees in both direction but It is a very small area bettween 70-110 degrees when it still rotates in the opposite direction. I think that's because the device traker doesn't update at the same rate as drag gesture or it doesn't have the same acurracy.

I am having trouble accessing and controlling @IBOutlet variables from other ViewControllers. More specifically, I want to control that @IBOutlet variable based on real-time changes in the variable value of another ViewController. Control is possible in the viewcontainer that contains the @IBOutlet variable, but when trying to control it from another viewcontainer, the message "Thead1: Fatal error: Unexpectedly found nil while implicitly unwrapping an Optional value" appears. Is there any possible way to do it? I think this will be difficult since thread1 in the error message means the main thread, so I tried to create a thread in the viewcontainer that has the @IBOutlet variable and access the variable of another viewcontainer to control the @IBOutlet variable inside the thread, but in this case, the variable value of the other viewcontainer that changes in real time is fixed to the value at the moment the thread is created, and the value that changes in real time after that cannot be retrieved. And I don't think using threads for this purpose is a good way. I sincerely ask for help from all the experts. If I can solve this, it will be easy to create the rest of the app structure. Sincerely !

Ever since updating to iOS18, CarPlay has been buggy for me. One of the constant issues is that after it connects, when I select an app (eg google maps or Spotify), the entire app will freeze. This happens regardless of the app I choose. Nothing on the app will be responsive unless I use the physical car controls to back out of the app. Once I’m on the main view of carplay (where it shows all the apps or where it shows the maps/audio mixes screen) then carplay becomes responsive again. But since I can’t use any of the apps as soon as I select one, I have to reboot my phone to resolve the issue. However, the issue will just happen again ok a subsequent attempt to connect. Some times it will work ok, probably happens again every 2-3 times I connect. This never happened prior to iOS18. Any suggestions?

Something (or a lot) is janky about apps built for "My Mac - designed for iPad." Aside from things just not working, the amount of garbage spewed to the console during debugging is unmanageable. I can't see my own trace statements amongst screens and screens of repetitive nonsense. I right-clicked on it and set it to filter out errors, but I'd like to get notified of legitimate errors. Anyone employing a clever filtering method I'm not aware of?

I'm running on xcode 16, the project archives just fine on the local machine. However, with xcodecloud. It's running into exist code 70 on the following command xcodebuild -exportArchive -archivePath ..... #output Showing All Errors Only Build Archive Export archive for ad-hoc distribution Command exited with non-zero exit-code: 70 Command exited with non-zero exit-code: 70 Export archive for development distribution Command exited with non-zero exit-code: 70 Command exited with non-zero exit-code: 70 Export archive for app-store distribution Command exited with non-zero exit-code: 70 Command exited with non-zero exit-code: 70

I can't find any way to search for a song by title only. You can search for songs, but any term you provide appears to be applied to any metadata associated with the song. Look at the largely nonsensical results when I search for a song with the letters "de": In many cases, that string doesn't appear anywhere. I used MusicCatalogSearchRequest(term: searchTerm, types: [Song.self]) Likewise it stands to reason that people want to search for artist and album names using text strings. How do we do that?

Hi Apple Developer Community, I’m exploring ways to fine-tune the SNSoundClassifier to allow users of my iOS app to personalize the model by adding custom sounds or adjusting predictions. While Apple’s WWDC session on sound classification explains how to train from scratch, I’m specifically interested in using SNSoundClassifier as the base model and building/fine-tuning on top of it. Here are a few questions I have: 1. Fine-Tuning on SNSoundClassifier: Is there a way to fine-tune this model programmatically through APIs? The manual approach using macOS, as shown in this documentation is clear, but how can it be done dynamically - within the app for users or in a cloud backend (AWS/iCloud)? Are there APIs or classes that support such on-device/cloud-based fine-tuning or incremental learning? If not directly, can the classifier’s embeddings be used to train a lightweight custom layer? Training is likely computationally intensive and drains too much on battery, doing it on cloud can be right way but need the right apis to get this done. A sample code will do good. 2. Recommended Approach for In-App Model Customization: If SNSoundClassifier doesn’t support fine-tuning, would transfer learning on models like MobileNetV2, YAMNet, OpenL3, or FastViT be more suitable? Given these models (SNSoundClassifier, MobileNetV2, YAMNet, OpenL3, FastViT), which one would be best for accuracy and performance/efficiency on iOS? I aim to maintain real-time performance without sacrificing battery life. Also it is important to see architecture retention and accuracy after conversion to CoreML model. 3. Cost-Effective Backend Setup for Training: Mac EC2 instances on AWS have a 24-hour minimum billing, which can become expensive for limited user requests. Are there better alternatives for deploying and training models on user request when s/he uploads files (training data)? 4. TensorFlow vs PyTorch: Between TensorFlow and PyTorch, which framework would you recommend for iOS Core ML integration? TensorFlow Lite offers mobile-optimized models, but I’m also curious about PyTorch’s performance when converted to Core ML. 5. Metrics: Metrics I have in mind while picking the model are these: Publisher, Accuracy, Fine-Tuning capability, Real-Time/Live use, Suitability of iPhone 16, Architectural retention after coreML conversion, Reasons for unsuitability, Recommended use case. Any insights or recommended approaches would be greatly appreciated. Thanks in advance!

Hello all, I'm finding myself with a compile error when trying to use a defined UTType for Transferable conformance when the type is also an AppEntity. The compiler error is Could not determine the identifier of `.todo`. Please use a UTType defined by the UniformTypeIdentifiers framework However, said compiler error only shows up after adding AppEntity conformance. So, in order to reproduce: Create any type, conform to Codable struct Todo: Codable { var id: UUID var title: String var completed: Bool } Create a UTType extension for the new type extension UTType { public static let todo: UTType = UTType(exportedAs: "org.nameghino.types.todo") } Add Transferable conformance extension Todo: Transferable { static var transferRepresentation: some TransferRepresentation { CodableRepresentation(contentType: .todo) ProxyRepresentation(exporting: \.title) } } At this point, the code compiles correctly on Xcode 16.2 beta 2 (16C5013f) Add AppEntity conformance extension Todo: AppEntity { static var typeDisplayRepresentation: TypeDisplayRepresentation = "todo_title" static var defaultQuery = Todo.Query() var displayRepresentation: DisplayRepresentation { DisplayRepresentation(title: "\(title)") } struct Query: EntityQuery { typealias Entity = Todo init() {} func entities(for identifiers: [UUID]) async throws -> [Todo] { return [] } func suggestedEntities() async throws -> [Entity] { return [] } } } Now the code is not compiling with the aforementioned error.

Not able to replicate this myself but have had a couple of users report this. I have a Finder Sync Extension. It does not, at least intentionally, change any sidebar icons. The hosting app mostly uses asset catalogs and the icon file it specifies in its info.plist is a icns file, not an iconset. Any idea what may be causing this? Seems odd to me that there isn't some explicit setting to enable this instead of requiring some set of configurations lining up.

Running xcrun xcresulttool get build-results --path ResultFile does not always show the warnings that the build emitted, If I run the legacy command, xcrun xcresulttool get --legacy --path ResultFile against the same file, there are (numerous) warnings, where the non-legacy call above shows no warnings.

We're build a pkg with three apps in it from the command line. There is one primary app and two supporting apps. We build a folder structure inside a temp directory like below (some folder names replaced with generic ones): mkdir -p ./tmp/Applications/.hiddenfolder/ mkdir -p ./tmp/Library/Application\ Support/Company/ mkdir -p ./tmp/Library/Preferences/ mkdir -p ./tmp/Library/Logs/Company/ mkdir -p ./tmp/Library/LaunchAgents/ mkdir -p ./tmp/Library/Company/ mkdir -p ./tmp/Library/LaunchDaemons/ #Grant Logs Folder Read-Write Access to All chmod a+rw ./tmp/Library/Logs/Company/ chmod a+rw ./tmp/Library/Application\ Support/Company/ We then build and sign each app dependency and place them into the temporary folder. For each app we're calling: xcodebuild -workspace "$PROJECT" -scheme "$TARGET" -configuration Release -derivedDataPath "$WORKING" clean build codesign --force --deep -o runtime --entitlements "../$TARGET/$APPLICATION.entitlements" --sign "$DEVKEY" "$WORKING/Build/Products/Release/$APPLICATION.app" cp -R "$WORKING/Build/Products/Release/$APPLICATION.app" "$DESTINATION" The primary app is copied into ./tmp/Applications/.hiddenfolder/ . The other two apps are put in ./tmp/Library/Company/ and ./tmp/Applications/ We then create the component list, build, and notarize the final pkg using the script below: Some definitions of the variables used below: IDENTIFIER=com.company.pkg.app1 (not real id but an example) ROOT=./tmp SCRIPTS=./scripts GUI=./pkggui pkgbuild --analyze --identifier "$IDENTIFIER" --version "$VERSION" --root "$ROOT" --scripts "$SCRIPTS" "$NAME-tmp.plist" /usr/libexec/PlistBuddy -c "SET 0:BundleIsRelocatable NO" "$NAME-tmp.plist" /usr/libexec/PlistBuddy -c "SET 1:BundleIsRelocatable NO" "$NAME-tmp.plist" /usr/libexec/PlistBuddy -c "SET 2:BundleIsRelocatable NO" "$NAME-tmp.plist" pkgbuild --identifier "$IDENTIFIER" --version "$PKGVERSION" --root "$ROOT" --scripts "$SCRIPTS" --component-plist "$NAME-tmp.plist" "$NAME-tmp.pkg" productbuild --synthesize --package "$NAME-tmp.pkg" distribution.xml sed -i "" \ -e '$ i\ \ <title>App1</title>' \ -e '$ i\ \ <background file="background.icns" alignment="bottomleft" scaling="proportional" />' \ -e '$ i\ \ <welcome file="welcome.txt" />' \ -e '$ i\ \ <installation-check script="InstallationCheck()"/> \ <script> \ function InstallationCheck(prefix) { \ if (system.compareVersions(system.version.ProductVersion, '12.0') &lt; 0) { \ my.result.message = "This update requires OS X version 12.0 or later."; \ my.result.type = "Fatal"; \ return false; \ } \ return true; \ } \ </script>' \ "distribution.xml" productbuild --distribution distribution.xml --resources "$GUI" --package-path "./$NAME-tmp.pkg" --sign "$DEVKEY" "$NAME.pkg" Once built and notarized this pkg becomes the base for the installers we give to customers. For each customer we have some custom parameters we set in a plist file inside the pkg, which requires us to expand the pkg out, add the plist file to /Library/Preferences/ in the expanded pkg, and then flattent/re-notarize the edited pkg. What we're running into is that the primary app (App1 above) will intermittently disappear after installation. We check all of the files we lay down in the postinstall script, and usually it detects the app in the correct location (/Applications/.hiddenfolder/), so it appears that it is correctly laying the files down but something is removing the app after installation. A couple of times the postinstall script has detected that the app is not in the correct place and fails, but usually the install will finish and only the other two apps remain. So far we've found no logs or evidence of it being moved or deleted; it just ceases to exist after installation. Has anyone else had this issue and found a solution?

When you launch Xcode and then open Devices and Simulators, and connect your Apple TV 4K, you have a new menu item in Settings named Developer. If you close Xcode, the item stays, but if you restart the Apple TV 4K, it's gone until the next time you open Xcode and pair it again. Is there a way to leave it there permanently? I'm not a developer, but it's still useful to me because it has the playback HUD with lots of information about the codecs, streaming bitrate and so on, and since I'm an A/V nerd, that is quite useful to me.

I'm attempting to use NWConnection as a websocket given a NWEndpoint returned by NWBrowser, setup like: let tcpOptions = NWProtocolTCP.Options() tcpOptions.enableKeepalive = true tcpOptions.keepaliveIdle = 2 let parameters = NWParameters(tls: nil, tcp: tcpOptions) parameters.allowLocalEndpointReuse = true parameters.includePeerToPeer = true let options = NWProtocolWebSocket.Options() options.autoReplyPing = true options.skipHandshake = true parameters.defaultProtocolStack.applicationProtocols.insert(options, at: 0) self.connection = NWConnection(to: endpoint, using: parameters) The initial connection does make it to the ready state but when I first try to send a text message over the websocket, i get nw_read_request_report [C1] Receive failed with error "Input/output error" nw_flow_prepare_output_frames Failing the write requests [5: Input/output error] nw_write_request_report [C1] Send failed with error "Input/output error" immediately, and the websocket is closed. Send code here: let encoder = JSONEncoder() let dataMessage = try encoder.encode(myMessage) let messageMetadata = NWProtocolWebSocket.Metadata(opcode: .text) let context = NWConnection.ContentContext(identifier: "send", metadata: [messageMetadata]) connection.send(content: dataMessage, contentContext: context, completion: .contentProcessed({ error in if let error = error { print (error) } })) What would typically cause the Input/output error when writing? Am I doing something obviously wrong or is there something else I can do to get additional debug information? Thanks in advance for any help.

Hi! I'm creating an app like this: Using Image Tracking to set world anchor in real world first. The timeline in Reality Composer Pro scene needs to be played in same time(for the people in same place using the app). People using the app will see the same contents in same position in same time in same place. I already made Image Tracking feature worked. But the big problem is "Synchronization". I found Group Activities and TabletopKit to solve the problem. But I don't know if this are the right modules for this project. How do I solve this problem technically? If you have ideas, please let me know. I really need help for this.

I'm building a custom camera screen that displays the camera image on a preview layer and then captures an image, using AVCaptureSession. When the picture is captured, I immediately load it into a UIImageView in order to display it to the user for approval. I've actually done this many times before, but this is the first time I've tried to do it in an app that supports interface rotation. If I hold the phone in Portrait mode and capture a picture, everything works as expected. When the user rotates the phone into Landscape orientation, I detect this and I replace the preview layer (AVCaptureVideoPreviewLayer) with a new one, specifying connection.videoRotationAngle in order to make the image appear in the right orientation. I'm a little surprised that this is necessary, and it's not a smooth transition, but that doesn't matter. What does matter is that when I capture the image, it is in the wrong orientation. I tried rotating it myself, but this doesn't seem to make any difference. What am I doing wrong?

Our app involves using the camera to scan barcodes or QR codes, with a working distance of about 5 cm. However, we’ve noticed variations in the focus distance of camera lenses across different iPhone models. Currently, we mainly use two types of lenses: wide-angle and ultra-wide-angle. • For iPhone 13 and earlier models, we use the wide-angle lens. • For iPhone 13 Pro and later models, we use the ultra-wide-angle lens. We are not certain if this setup is correct since we don’t have all iPhone models to test.
There is a users have reported focus issues on his iPhone 15. We would like to ask if there’s a resource where we can find the minimum focus distance of different cameras in each iPhone model. This is to verify whether our current configuration is accurate. Alternatively, if such data is not readily available, could apple tam advise which camera should be used on various iPhone models for scenarios with a working distance of approximately 5 cm? Thank you!
