Chaining app intents in code
I would like to split up my intents into smaller intents with more atomic pieces of functionality that I can then call one intent from another. For example: struct SumValuesIntent: AppIntent { static var title: LocalizedStringResource { "Sum Values" } let a: Int let b: Int init(a: Int, b: Int) { self.a = a self.b = b } init() { self.init(a: 0, b: 0) } func perform() async throws -> some IntentResult { let sum = a + b print("SumValuesIntent:", sum) return .result(value: sum) } } struct PrintValueIntent: AppIntent { static var title: LocalizedStringResource { "Print Value" } let string: String init(string: String) { self.string = string } init() { self.init(string: "") } func perform() async throws -> some IntentResult { print("PrintValueIntent:", string) return .result() } } What is the best way to chain intents like these? I tried .result(opensIntent: PrintValueIntent(string: String(describing: sum))) as the return type of SumValuesIntent.perform but that doesn't seem to work. Then I tried try await PrintValueIntent(string: String(describing: sum)).perform() as the return type and that works but I'm not sure that's the correct way to do it.

App Intents "Text" parameters seem broken in iOS 17.6 beta
I'm getting widespread reports from users trialling iOS 17.6 public beta that Siri Shortcuts are failing whenever they enter any text that looks like a URL. It's getting reported to me because my app happens to have an app intent with a string parameter which can contain a URL in some circumstances. However it's easily reproducible outside of my app: just create a 2 line shortcut like the one below. If you change "This is some text" to "https://www.apple.com" the shortcut below will fail: In iOS 17.5 entering "https://www.apple.com" works fine. I've raised feedback on this (FB14206088) but can anyone confirm that this is indeed a bug and not some weird new feature of Shortcuts where the contents of a variable can somehow change the type of a variable? It would be very, very bad if this were so.

iOS 18 App Intents while supporting iOS 17
iOS 18 App Intents while supporting iOS 17 Hello, I have an existing app that supports iOS 17. I already have three App Intents but would like to add some of the new iOS 18 app intents like ShowInAppSearchResultsIntent. However, I am having a hard time using #available or @available to limit this ShowInAppSearchResultsIntent to iOS 18 only while still supporting iOS 17. Obviously, the ShowInAppSearchResultsIntent needs to use @AssistantIntent which is iOS 18 only, so I mark that struct as @available(iOS 18, *). That works as expected. It is when I need to add this "SearchSnippetIntent" intent to the AppShortcutsProvider, that I begin to have trouble doing. See code below: struct SnippetsShortcutsAppShortcutsProvider: AppShortcutsProvider { @AppShortcutsBuilder static var appShortcuts: [AppShortcut] { //iOS 17+ AppShortcut(intent: SnippetsNewSnippetShortcutsAppIntent(), phrases: [ "Create a New Snippet in \(.applicationName) Studio", ], shortTitle: "New Snippet", systemImageName: "rectangle.fill.on.rectangle.angled.fill") AppShortcut(intent: SnippetsNewLanguageShortcutsAppIntent(), phrases: [ "Create a New Language in \(.applicationName) Studio", ], shortTitle: "New Language", systemImageName: "curlybraces") AppShortcut(intent: SnippetsNewTagShortcutsAppIntent(), phrases: [ "Create a New Tag in \(.applicationName) Studio", ], shortTitle: "New Tag", systemImageName: "tag.fill") //iOS 18 Only AppShortcut(intent: SearchSnippetIntent(), phrases: [ "Search \(.applicationName) Studio", "Search \(.applicationName)" ], shortTitle: "Search", systemImageName: "magnifyingglass") } let shortcutTileColor: ShortcutTileColor = .blue } The iOS 18 Only AppShortcut shows the following error but none of the options seem to work. Maybe I am going about it the wrong way. 'SearchSnippetIntent' is only available in iOS 18 or newer Add 'if #available' version check Add @available attribute to enclosing static property Add @available attribute to enclosing struct Thanks in advance for your help.

Can you match a new photo with existing images?
I'm looking for a solution to take a picture or point the camera at a piece of clothing and match that image with an image the user has stored in my app. I'm storing the data in a Core Data database as a Binary Data object. Since the user also takes the pictures they store in the database I think I cannot use pre-trained Core ML models. I would like the matching to be done on device if possible instead of going to an external service. That will probably describe the item based on what the AI sees, but then I cannot match the item with the stored images in the app. Does anyone know if this is possible with frameworks as Vision or VisionKit?

FactoryInstall Unable to query results, error: 5
I am developing an iPhone application. When I start testing in a simulator or on an actual device, I get the following message depending on the model. I don't see any problem with the actual operation of the app, but I don't know how to resolve this error. #FactoryInstall Unable to query results, error: 5 Unable to list voice folder Unable to list voice folder Unable to list voice folder Unable to list voice folder Unable to list voice folder I have tried to resolve the problem by following the steps below, but it hasn’t had any affect on the error. Is it OK to leave this error as it is? If you know how to resolve it, please let me know. Clear the Xcode cache: Go to the path of the DerivedData folder and delete all of its contents. Clean Build folder: Select "Product" -> "Clean Build Folder" from the Xcode menu. Restart: Restart Xcode and the simulator. Software update: Make sure you are using the latest version of Xcode and macOS. Reinstallation: Uninstall Xcode once and reinstall it. Reset the simulator

Unexpected URLRepresentableIntent behaviour
After watching the What's new in App Intents session I'm attempting to create an intent conforming to URLRepresentableIntent. The video states that so long as my AppEntity conforms to URLRepresentableEntity I should not have to provide a perform method . My application will be launched automatically and passed the appropriate URL. This seems to work in that my application is launched and is passed a URL, but the URL is in the form: FeatureEntity/{id}. Am I missing something, or is there a trick that enables it to pass along the URL specified in the AppEntity itself? struct MyExampleIntent: OpenIntent, URLRepresentableIntent { static let title: LocalizedStringResource = "Open Feature" static var parameterSummary: some ParameterSummary { Summary("Open \(\.$target)") } @Parameter(title: "My feature", description: "The feature to open.") var target: FeatureEntity } struct FeatureEntity: AppEntity { // ... } extension FeatureEntity: URLRepresentableEntity { static var urlRepresentation: URLRepresentation { "https://myurl.com/\(.id)" } }

Code missing from WWDC session video 10210
I noticed the code snippets are missing from the wwdc2024 10210 video titled Bring your app’s core features to users with App Intents https://developer.apple.com/videos/play/wwdc2024/10210/ It would be useful if those could be added. I also noticed the transcript is missing from the web version but it is in the Developer app, that is odd.

Siri only uses first App Shortcut defined
Using App Shortcuts with app intents, Siri only responds to the first shortcut defined in the app shortcut below. struct MementoShortcuts: AppShortcutsProvider { u/AppShortcutsBuilder static var appShortcuts: [AppShortcut] { AppShortcut( intent: SaveLinkIntent(), phrases: ["Add a link to \(.applicationName)", "Add \(\.$url) to \(.applicationName)", "Make a new link in \(.applicationName)", "Create a new link in \(.applicationName) from \(\.$url)"], shortTitle: "Add Link", systemImageName: "link.badge.plus" ) AppShortcut( intent: LinkViewedIntent(), phrases: [ "Mark a link I saved in \(.applicationName) as viewed", "Mark \(\.$link) as viewed in \(.applicationName)", "Set link in \(.applicationName) to viewed", "Change status of \(\.$link) to viewed in \(.applicationName)", ], shortTitle: "Mark Link as Viewed", systemImageName: "book" ) } } I have tried switching the order and she always uses the one that comes first. Both show up in the shortcuts app as an app shortcut, but only one shortcut is recognized by Siri even if I say the other one's phrase.

Vision and iOS18 - Failed to create espresso context.
I'm playing with the new Vision API for iOS18, specifically with the new CalculateImageAestheticsScoresRequest API. When I try to perform the image observation request I get this error: internalError("Error Domain=NSOSStatusErrorDomain Code=-1 \"Failed to create espresso context.\" UserInfo={NSLocalizedDescription=Failed to create espresso context.}") The code is pretty straightforward: if let image = image { let request = CalculateImageAestheticsScoresRequest() Task { do { let cgImg = image.cgImage! let observations = try await request.perform(on: cgImg) let description = observations.description let score = observations.overallScore print(description) print(score) } catch { print(error) } } } I'm running it on a M2 using the simulator. Is it a bug? What's wrong?

tf.function decorator with tensorflow-metal breaks tf.signal.fft3d()
I consistently receive corrupted results from tf.signal.fft3d() when it is within a function that has a @tf.function decorator. The results are all zero (0.) for entries after a certain x index (see image). Surprisingly, the issue depends on the matrix size. For example, (1023, 1023, 287) works but (1023, 1023, 575) does not. The issue is problematic because it occurs silently and not for all matrix sizes, i.e. can easily slip through tests. The error occurs only when tensorflow-metal is installed. The Tensorflow version is 2.16.1. My hardware is a Macbook Pro M3 Max with 40 GPU cores, 128 GB RAM running MacOS Sonoma version 14.5 (23F79). A Python environment to reproduce the bug can be created as follows: conda create --name tfmetalbug python=3.11.9 conda activate tfmetalbug pip install tensorflow tensorflow-metal conda install matplotlib The following code reproduces the issue: import tensorflow as tf import numpy as np import matplotlib.pyplot as plt # Wrap fft3d with tf.function @tf.function def fft3d_wrapper_function(x): return tf.signal.fft3d(x) # Generate a 3D image img = tf.random.normal(shape=(1023, 1023, 575), stddev=1., dtype=float) # generate random 3d image img = tf.dtypes.cast(img, tf.complex64) # convert to complex values # Compute the 3D FFT img_fft = fft3d_wrapper_function(img) # Visualize the 3D FFT plt.imshow(np.real(img_fft)[:, img_fft.shape[1]//2+10, :], cmap="gray", vmin=-0.001, vmax=0.001) plt.savefig("fft3d_wrapper_function.png") For me, removing the @tf.function decorator has resolved the issue.

Dynamically train AI model on contents of a folder.
Hellooo, I’m looking to implement an OpenAI assistant using APIs but I want to do this locally on a group of files. I want to be able to train a GPT on the contents of a folder for example. Does anyone have any experience in this? It seems OpenAI needs a lot of uploading on each request if I were to do this with their API after playing around (but this feels like I’m missing something). It’s also quite costly to use. I was hoping to use local machine learning and models but this is quite limited in what it can do (eg Lumachain)
