In the WWDC24 What’s New In Create ML at 6:03 the presenter introduced TimeSeriesClassifier as a new component of Create ML Components. Where are documentation and code examples for this feature? My app captures accelerometer time series data that I want to classify. Thank you so much!

I am using Apple’s Vision framework with DetectHorizonRequest to detect the horizon in an image. Here is my code: func processHorizonImage(_ ciImage: CIImage) async { let request = DetectHorizonRequest() do { let result = try await request.perform(on: ciImage) print(result) } catch { print(error) } } After calling the perform method, I am getting result as nil. To ensure the request's correctness, I have verified the following: The input CIImage is valid and contains a visible horizon. No errors are being thrown. The relevant frameworks are properly imported. Given that my image contains a clear horizon, why am I still not getting any results? I would appreciate any help or suggestions to resolve this issue. Thank you for your support! This is the image

Hello, I’m working on a program that analyzes video files frame by frame to detect human poses in each frame. However, during the process of reading observations from the stream, the analysis frequently stops with the following error: [LOG_ERROR] /Library/Caches/com.apple.xbs/Sources/MediaAnalysis/VideoProcessing/VCPHumanPoseImageRequest.mm[85]: code -18 [LOG_ERROR] /Library/Caches/com.apple.xbs/Sources/MediaAnalysis/VideoProcessing/VCPHumanPoseImageRequest.mm[178]: code -18 The error was caught and printed using a do-catch block, and here is the output: Error Domain=NSOSStatusErrorDomain Code=-18 "Error: failed to processImage" UserInfo={NSLocalizedDescription=Error: failed to processImage} While the do-catch block helps prevent the app from crashing, the frames following the error cannot be analyzed. I’m hoping to understand the cause of this error, or find a way to skip the problematic frames and continue analyzing the subsequent ones. My development environment is Xcode Version 16.0 (16A242d) and iOS 18.0. Thank you for your help. (Attaching my code below.) let videoProcessor = VideoProcessor(videoURL) let bodyPoseRequest = DetectHumanBodyPoseRequest() let asset = AVURLAsset(url: videoURL) let videoTrack = try await asset.loadTracks(withMediaType: .video).first let bodyPoseStream = try await videoProcessor.addRequest(bodyPoseRequest) videoProcessor.startAnalysis() do { for try await observations in bodyPoseStream { guard let observation = observations.first else { continue } if let timeRange = observation.timeRange { /// do something... } } } catch { print("\(error.localizedDescription)") }

Hi All, Is it possible to record a video using the Object Capture instead of taking a series of pictures ? Is it possible to get the bounding box coordinates of the object we capture ?

Hi, I'm training a model that should detect a forehand and a backend stroke. The data looks like this: activity,timestamp,Acceleration_X,Acceleration_Y,Acceleration_Z,Rotation_X,Rotation_Y,Rotation_Z forehand,0.0,0.08,-0.08,0.03,0.18,0.26,0.32 I can load it in Create ML but it's showing the acceleration and rotation x,y,z as seperate Doubles and not as one feature. What do I have to change to make this work? Thank you

Hello. I can't find anything about the SSML that is used in Apple's speech synthesis. SSML from Google, Amazon and W3C either don't work or work incorrectly. Where is Apple's documentation for their implementation of SSML?

hi, I am currently running LSTM on TensorFlow. However, when i switched from keras2 to keras3. code running time has increased 10 times -- it seems there is no GPU acceleration. Here is my code: batch size = 256 optimiser = adam activation = tanh _______________________________________________ Layer (type) Output Shape Param # ============================================= input_1 (InputLayer) [(None, 7, 16)] 0 bidirectional (Bidirection (None, 7, 320) 226560 al) bidirectional_1 (Bidirecti (None, 7, 512) 1181696 onal) bidirectional_2 (Bidirecti (None, 256) 656384 onal) dense (Dense) (None, 1) 257 ============================================== Total params: 2064897 (7.88 MB) Trainable params: 2064897 (7.88 MB) Non-trainable params: 0 (0.00 Byte) ______________________________________________ This is keras 3.6.0 + tensorflow 2.17.0 + tensorflow-metal 1.1.0 training status: Training------------ Epoch 1/200 28/681 ━━━━━━━━━━━━━━━━━━━━ 8:13 756ms/step - loss: 0.5901 - mape: 338.6876 - mse: 0.8591 This is keras 2.14.0 + tensorflow 2.14.0 + tensorflow-metal 1.1.0 training status: Training------------ Epoch 1/200 681/681 [==============================] - 37s 49ms/step - loss: 3.6345 - mape: 499038.7500 - mse: 34.4148 - val_loss: 3.5452 - val_mape: 41.7964 - val_mse: 32.0133 - lr: 0.0010 Is that because keras3 has no GPU support on macos? Apart from that, if I change LSTM activation from tanh to sigmoid in keras2, it does not have GPU support as well. My system is 15.0.1 and the code was running on python3.11 I am not sure why these happen. Thanks

I wanted to join the Apple Intelligence after I updated my iPhone 15pro to iOS 18.1 beta. But it is still showing that I’m in the waitlist. It has been almost one day! Why? Is it normal?

I'm trying to run a coreML model. This is an image classifier generated using: let parameters = MLImageClassifier.ModelParameters(validation: .dataSource(validationDataSource), maxIterations: 25, augmentation: [], algorithm: .transferLearning( featureExtractor: .scenePrint(revision: 2), classifier: .logisticRegressor )) let model = try MLImageClassifier(trainingData: .labeledDirectories(at: trainingDir.url), parameters: parameters) I'm trying to run it with the new async Vision api let model = try MLModel(contentsOf: modelUrl) guard let modelContainer = try? CoreMLModelContainer(model: model) else { fatalError("The model is missing") } let request = CoreMLRequest(model: modelContainer) let image = NSImage(named:"testImage")! let cgImage = image.toCGImage()! let handler = ImageRequestHandler(cgImage) do { let results = try await handler.perform(request) print(results) } catch { print("Failed: \(error)") } This gives me Failed: internalError("Error Domain=com.apple.Vision Code=7 "The VNDetectorProcessOption_ScenePrints required option was not found" UserInfo={NSLocalizedDescription=The VNDetectorProcessOption_ScenePrints required option was not found}") Please help! Am I missing something?

Using an iPhone 15 Pro. I'm in Australia on iOS 18.2 Beta 1 but there's no mention of Apple Intelligence anywhere in the phone. Settings looks identical without the menu for AI, there's no playground image generation. It's as if my phone doesn't know it exists

So, I was working with organizing the Home Screen. Then I lost track of where I was and planed to just move it to the library but instead deleted it. How do I get It back?

Almost all the functions in Accelerate are for single precision (Float) and double precision (Double) operations. However, I stumbled upon three integer arithmetic functions which operate on Int32 values. Are there any more functions in Accelerate that operate on integer values? If not, then why aren't there more functions that work with integers?

I'm using an iPhone 15 Pro Max and running developer beta 18.2 released today. I've already been an 'Apple Intelligence' user and now have been able to link it with my PAID ChatGPT account. HOWEVER; I'm searching for these Image features everyone seems to be posting about and cannot find them anywhere. I'm apparently supposed to sign up for beta access to the Image features through some new Apple natively released app that was supposedly included in this build update, which I cannot find. What gives??!!

I'm using the iOS 18.2 beta on my iPhone 15 Pro Max, but can't find Apple Intelligence, and the Settings app still shows the Old Siri logo.

Originally when Apple Intelligence launched there are some T&C for using and activate this Apple Intelligence. For activating Apple Intelligence at China first of all purchased iPhone must be non-Chinese iPhone means that the iPhone aren’t purchased in China not include Hong Kong and Macau. Also if use this Chinese Apple account are also unable to activate the Apple Intelligence. To activate the Apple Intelligence, I have travel to Hong Kong and purchase iPhone 16 pro Max. To reach the requirement of activating Apple Intelligence, I’ve decided to switch my region from China to United States. I’ve started to switch my account from October 19, CST 2:00am, Shanghai time 3:00pm. Till now CST time 8:30am October 24, Shanghai Time 9:30pm I still can’t join the Apple Intelligence waitlist. I’m also upgraded my phone to iOS 18.2. I’ve contacted the Apple support using my Chinese phone number and it transferred to me Philippines Apple support team. It seems like the Philippine Apple support team doesn’t help me get anything. The Philippine Apple support team keeps saying that the beta version iOS right now in my phone has some problem on it. But when I log out this Apple ID, and changed to another Apple ID that is UK ones. I can successfully enable the Apple Intelligence. What does this say?! This shows that my Apple account has a problem on it. It doesn’t switch successfully to United States server! And the Philippine Apple support team keep asking me to restore my iPhone like crazy! I’ve told them that I have used several Apple account that is from United States and United Kingdom that can successfully enable the Apple Intelligence. But the Philippine Apple support team said that my Apple account doesn’t have any problem! Apple please solve the problem! Anyone who have facing this kind of problem please share to us!!! Cheers!

I downloaded the RC beta version on my Macbook and joined the waitlist so far I haven't received any message or any kind of notifications that I'm in but I have a question kinda silly but just want confirmation. By joining the beta and AI on my MacBook, whenever the official version is released, am I gonna have AI on my iPhone since already joined AI through my MacBook in the beta version? Kinda curious about it.

Is anyone else seeing their apps crash on iOS/macOS 17.4/14.4 and newer when building a project that simply just includes the iOS 18 @AssistantIntent Macro? The beta 4 releases still have this problem. There are no notes about this that I have seen in the beta release notes. Crash message shown in console when trying to run on 17.4, 17.5, 17.5.1, etc: dyld[21935]: Symbol not found: _$s10AppIntents15AssistantSchemaV06IntentD0VAC0E0AAWP Referenced from: <F7A1FEF0-F3B0-379C-A914-D1FB0BA7C693> /Users/jonathan/Library/Developer/CoreSimulator/Devices/CA308F47-BCA8-4429-8599-1BB1CCEAB5B6/data/Containers/Bundle/Application/D7DC8E16-90DB-406A-A521-20F18326E4A7/IntentDemo.app/IntentDemo.debug.dylib Expected in: <88E18E38-24EC-364E-94A1-E7922AD247AF> /Library/Developer/CoreSimulator/Volumes/iOS_21F79/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 17.5.simruntime/Contents/Resources/RuntimeRoot/System/Library/Frameworks/AppIntents.framework/AppIntents Obviously, the new Apple Intelligence AssistantIntents only work on the 2024 OS releases. However, even when these new App Intents are marked with @available(iOS 18, macOS 15, *), the app crashes on any earlier OS version. But it runs just fine on iOS 18 and macOS 15... I would love for me to just have done something wrong but I don’t think I have… Here is the sample project: https://github.com/JTostitos/FB14323923 Maybe it's a compiler issue thats failing to strip out the macro when building for older OS's or an Xcode issue - I have no idea. I just would like to know why its not working and how to resolve it. Thanks in advance for anyones help...

I integrated the image playground sheet in my app, however when I select Take Photo on the iOS version of my app it just reloads the sheet. After several attempts I get the below error message. This issue doesn’t occur on the macOS version of my app, where it first requests camera permission before allowing me to take the photo. I’m not sure if this is happening because I don’t request the camera permission anywhere in my app. My app doesn’t use the camera at all apart from the Take Photo feature which is part of the image playground sheet. Feedback ID: FB15591786

I have updated the ios 18.2. The image playground is stuck at access requested and its been one and a half day. When will this be available on my phone i am using 16 pro max.
