I'm implementing an App Intent for my iOS app that helps users plan trip activities. It only works when run as a shortcut but not using voice through Siri. There are 2 issues:
The ShortcutsTripEntity will only accept a voice input for a specific trip but not others.
I'm stuck with a throwing error when trying to use requestDisambiguation() on the activity day @Parameter property.
How do I rectify these issues.
This is blocking me from completing a critical feature that lets users quickly plan activities through Siri and Shortcuts.
Expected behavior for trip input: The intent should make Siri accept the spoken trip input from any of the options.
Actual behavior for trip input: Siri only accepts the same trip when spoken but accepts any when selected by click/touch.
Expected behavior for day input: Siri should accept the spoken selected option.
Actual behavior for day input: Siri only accepts an input by click/touch but yet throws an error at runtime I'm happy to provide more code. But here's the relevant code:
struct PlanActivityTestIntent: AppIntent {
@Parameter(title: "Activity Day")
var activityDay: ShortcutsItineraryDayEntity
@Parameter(
title: "Trip",
description: "The trip to plan an activity for",
default: ShortcutsTripEntity(id: UUID().uuidString, title: "Untitled trip"),
requestValueDialog: "Which trip would you like to add an activity to?"
)
var tripEntity: ShortcutsTripEntity
@Parameter(title: "Activity Title", description: "The title of the activity", requestValueDialog: "What do you want to do or see?")
var title: String
@Parameter(title: "Activity Day", description: "Activity Day", default: ShortcutsItineraryDayEntity(itineraryDay: .init(itineraryId: UUID(), date: .now), timeZoneIdentifier: "UTC"))
var activityDay: ShortcutsItineraryDayEntity
func perform() async throws -> some ProvidesDialog {
// ...other code...
let tripsStore = TripsStore()
// load trips and map them to entities
try? await tripsStore.getTrips()
let tripsAsEntities = tripsStore.trips.map { trip in
let id = trip.id ?? UUID()
let title = trip.title
return ShortcutsTripEntity(id: id.uuidString, title: title, trip: trip)
}
// Ask user to select a trip. This line would doesn't accept a voice // answer. Why?
let selectedTrip = try await $tripEntity.requestDisambiguation(
among: tripsAsEntities,
dialog: .init(
full: "Which of the \(tripsAsEntities.count) trip would you like to add an activity to?",
supporting: "Select a trip",
systemImageName: "safari.fill"
)
)
// This line throws an error
let selectedDay = try await $activityDay.requestDisambiguation(
among: daysAsEntities,
dialog:"Which day would you like to plan an activity for?"
)
}
}

Recently, I'm trying to deploy some third-party LLM to Apple devices.
The methodoloy is similar to https://github.com/Anemll/Anemll.
The biggest issue I'm having now is the runtime memory usage.
When there are multiple functions in a model (mlpackage or mlmodelc), the runtime memory usage for weights is somehow duplicated when I load all of them. Here's the detail:
I created my multifunction mlpackage following https://apple.github.io/coremltools/docs-guides/source/multifunction-models.html
I loaded each of the functions using the generated swift class:
let config = MLModelConfiguration()
config.computeUnits = MLComputeUnits.cpuAndNeuralEngine
config.functionName = "infer_512";
let ffn1_infer_512 = try! mimo_FFN_PF_lut4_chunk_01of02(configuration: config)
config.functionName = "infer_1024";
let ffn1_infer_1024 = try! mimo_FFN_PF_lut4_chunk_01of02(configuration: config)
config.functionName = "infer_2048";
let ffn1_infer_2048 = try! mimo_FFN_PF_lut4_chunk_01of02(configuration: config)
I observed that RAM usage increases linearly as I load each of the functions.
Using instruments, I see that there are multiple HWX files generated and loaded, each of which contains all the weight data.
My understanding of what's happening here:
The CoreML framework did some MIL->MIL preprocessing before further compilation, which includes separating CPU workload from ANE workload.
The ANE part of each function is moved into a separate MIL file then compile separately into a HWX file each.
The problem is that the weight data of these HWX files are duplicated. Since that the weight data of LLMs is huge, it will cause out-of-memory issue on mobile devices.
The improvement I'm hoping from Apple:
I hope we can try to merge the processed MIL files back into one before calling ANECCompile(), so that the weights can be merged. I don't have control over that in user space and I'm not sure if that is feasible. So I'm asking for help here.
Thanks.

Hi,
I am new to developing on Apple’s platform yet I want to familiarize myself with Core ML and Core ML Tools. I was watching the WWDC24: Bring your machine learning and AI models to Apple Silicon video and was trying to follow along. After multiple attempts and much reading up on documentation, I am still unable to get a coherent script running that will convert the Mistral model that the host used and convert it to a valid Core ML model.
here is a pastebin to what i have currently:

Due to our min iOS version, this is my first time using .xcstrings instead of .strings for AppShortcuts.
When using the migrate .strings to .xcstrings Xcode context menu option, an .xcstrings catalog is produced that, as expected, has each invocation phrase as a separate string key.
However, after compilation, the catalog changes to group all invocation phrases under the first phrase listed for each intent (see attached screenshot). It is possible to hover in blank space on the right and add more translations, but there is no 1:1 key matching requirement to the phrases on the left nor a requirement that there are the same number of keys in one language vs. another. (The lines just happen to align due to my window size.)
What does that mean, practically?
Do all sub-phrases in each language in AppShortcuts.xcstrings get processed during compilation, even if there isn't an equivalent phrase key declared in the AppShortcut (e.g., the ja translation has more phrases than the English)? (That makes some logical sense, as these phrases need not be 1:1 across languages.)
In the AppShortcut declaration, if I delete all but the top invocation phrase, does nothing change with Siri?
Is there something I'm doing incorrectly?
struct WatchShortcuts: AppShortcutsProvider {
static var appShortcuts: [AppShortcut] {
AppShortcut(
intent: QuickAddWaterIntent(),
phrases: [
"\(.applicationName) log water",
"\(.applicationName) log my water",
"Log water in \(.applicationName)",
"Log my water in \(.applicationName)",
"Log a bottle of water in \(.applicationName)",
],
shortTitle: "Log Water",
systemImageName: "drop.fill"
)
}
}
Is the face and body detection service in the Vision framework a local model or a cloud model?

The WWDC25: Explore large language models on Apple silicon with MLX video talks about using your own data to fine-tune a large language model. But the video doesn't explain what kind of data can be used. The video just shows the command to use and how to point to the data folder. Can I use PDFs, Word documents, Markdown files to train the model? Are there any code examples on GitHub that demonstrate how to do this?

Dear Apple AI Research Team,
My name is Gong Jiho (“Hem”), a content strategist based in Seoul, South Korea.
Over the past few months, I conducted a user-led AI experiment entirely within ChatGPT — no code, no backend tools, no plugins.
Through language alone, I created two contrasting agents (Uju and Zero) and guided them into a co-authored modular identity system using prompt-driven dialogue and reflection.
This system simulates persona fusion, memory rooting, and emotional-logical alignment — all via interface-level interaction.
I believe it resonates with Apple’s values in privacy-respecting personalization, emotional UX modeling, and on-device learning architecture.
Why I’m Reaching Out
I’d be honored to share this experiment with your team.
If there is any interest in discussing user-authored agent scaffolding, identity persistence, or affective alignment, I’d love to contribute — even informally.
⚠ A Note on Language
As a non-native English speaker, my expression may be imperfect — but my intent is genuine.
If anything is unclear, I’ll gladly clarify.

I'm experimenting with the new SpeechTranscriber in macOS/iOS 26, transcribing speech from a prerecorded mp4 file. Speed and quality are amazing!
I've told the transcriber to include time indexes. Each run is always exactly one word, which can be very useful. When I look at the indexes the end of one run is always identical to the start of the next run, even if there's a pause.
I'd like to identify pauses, perhaps to generate something like phrases for subtitling. With each run of text going into the next I can't do this, other than using punctuation - which might be rather rough.
Any suggestions on detecting pauses, or getting that kind of metadata from the transcriber?
Here's a short sample, showing each run with the start, end, and characters in the run:
105.9 --> 107.04 I
107.04 --> 107.16 think
107.16 --> 108.0 more
108.0 --> 108.42 lighting

111.78 --> 111.84 that

The developer tutorial for visual intelligence indicates that the method to detect and handle taps on a displayed entity from the Search section is via an "OpenIntent" associated with your entity.
However, running this intent executes code from within my app. If I have the perform() method display UI, it always displays UI from within my app.
I noticed that the Google app's integration to visual intelligence has a different behavior-- tapping on an entity does not take you to the Google app -- instead, a Webview is presented sheet-style WITHIN the Visual Intelligence environment (see below)
How is that accomplished?

the specific context is that i would like to build an agent that monitors my phone call (with a customer support for example), and simiply identify whether or not im still put on hold, and notify me when im not.
currently after reading the doc, i dont think its possible yet, but im so annoyed by the customer support calls that im willing to go the distance and see if theres any way.
Hey
Tried using a few regular expressions and all fail with an error:
Unhandled error streaming response: A generation guide with an unsupported pattern was used.
Is there are a list of supported features? I don't see it in docs, and it takes RegExp.
Anything with e.g. [A-Z] fails.

We are developing Apple AI for overseas markets and adapting it for iPhone 17 and later models. When the system language and Siri language do not match—such as the system being in English while Siri is in Chinese—it may result in Apple AI being unusable. So, I would like to ask, how can this issue be resolved, and are there other reasons that might cause it to be unusable within the app?
In this WWDC25 session, it is explictely mentioned that apps should support AttributedString for text parameters to their App Intents.
However, I have not gotten this to work. Whenever I pass rich text (either generated by the new "Use Model" intent or generated manually for example using "Make Rich Text from Markdown"), my Intent gets an AttributedString with the correct characters, but with all attributes stripped (so in effect just plain text).
struct TestIntent: AppIntent {
static var title = LocalizedStringResource(stringLiteral: "Test Intent")
static var description = IntentDescription("Tests Attributed Strings in Intent Parameters.")
@Parameter
var text: AttributedString
func perform() async throws -> some IntentResult & ReturnsValue<AttributedString> {
return .result(value: text)
}
}
Is there anything else I am missing?
My app lets you create images with Image Playground. When the user approves an image I move it to the documents dir from the temp storage. With over a year of usage I’ve created a lot of images over time.
Out of nowhere the app stopped loading my custom creations from Image Playground saying it couldn’t find the files. It still had my VoiceOver strings I had added for each image and still had the custom categories I assigned them.
Debug code to look in the docs dir doesn’t find them. I downloaded the app’s container and only see the images I created as a test after the problem started.
But my ~70MB app is still taking up 300MB on my iPhone so it feels like they’re there but not accessible.
Is there anything else I can try?
I have an app that uses a couple of mlmodels (word tagger and gazetteer) and I’m trying to encrypt them before publishing.
The models are part of a package. I understand that Xcode can’t automatically handle the encryption for a model in a package the way it can within a traditional app structure.
Given that, I’ve generated the Apple MLModel encryption key from Xcode and am encrypting via the command line with:
xcrun coremlcompiler compile Gazetteer.mlmodel GazetteerENC.mlmodelc --encrypt Gazetteerkey.mlmodelkey
In the package manifest, I’ve listed the encrypted models as .copy resources for my target and have verified the URL to that file is good.
When I try to load the encrypted .mlmodelc file (on a physical device) with the line:
gazetteer = try NLGazetteer(contentsOf: gazetteerURL!)
I get the error:
Failed to open file: /…/Scanner.bundle/GazetteerENC.mlmodelc/coremldata.bin. It is not a valid .mlmodelc file.
So my questions are:
Does the NLGazetteer class support encrypted MLModel files?
Given that my models are in a package, do I have the right general approach?
Thanks for any help or thoughts.

I'm experimenting with Foundation Models and I'm trying to understand how to define a Tool whose input argument is defined at runtime. Specifically, I want a Tool that takes a single String parameter that can only take certain values defined at runtime.
I think my question is basically the same as this one: https://developer.apple.com/forums/thread/793471 However, the answer provided by the engineer doesn't actually demonstrate how to create the GenerationSchema. Trying to piece things together from the documentation that the engineer linked to, I came up with this:
let citiesDefinedAtRuntime = ["London", "New York", "Paris"]
let citySchema = DynamicGenerationSchema(
name: "CityList",
properties: [
DynamicGenerationSchema.Property(
name: "city",
schema: DynamicGenerationSchema(
name: "city",
anyOf: citiesDefinedAtRuntime
)
)
]
)
let generationSchema = try GenerationSchema(root: citySchema, dependencies: [])
let tools = [CityInfo(parameters: generationSchema)]
let session = LanguageModelSession(tools: tools, instructions: "...")
With the CityInfo Tool defined like this:
struct CityInfo: Tool {
let name: String = "getCityInfo"
let description: String = "Get information about a city."
let parameters: GenerationSchema
func call(arguments: GeneratedContent) throws -> String {
let cityName = try arguments.value(String.self, forProperty: "city")
print("Requested info about \(cityName)")
let cityInfo = getCityInfo(for: cityName)
return cityInfo
}
func getCityInfo(for city: String) -> String {
// some backend that provides the info
}
}
This compiles and usually seems to work. However, sometimes the model will try to request info about a city that is not in citiesDefinedAtRuntime. For example, if I prompt the model with "I want to travel to Tokyo in Japan, can you tell me about this city?", the model will try to request info about Tokyo, even though this is not in the citiesDefinedAtRuntime array.
My understanding is that this should not be possible – constrained generation should only allow the LLM to generate an input argument from the list of cities defined in the schema.
Am I missing something here or overcomplicating things?
What's the correct way to make sure the LLM can only call a Tool with an input parameter from a set of possible values defined at runtime?
Many thanks!

After exerting a custom model with nms=True.
In Xcode, the outputs show as:
confidence: MultiArray (0 × 5)
coordinates: MultiArray (0 × 4)
I want to set fixed shapes (e.g., 100 × 5, 100 × 4), but Xcode does not allow editing—the shape fields are locked. The model graph shows both outputs come directly from a NonMaximumSuppression layer.
Is it possible to set fixed output dimensions for NMS outputs in CoreML?
I watched this year WWDC25 "Read Documents using the Vision framework". At the end of video there is mention of new DetectHandPoseRequest model for hand pose detection in Vision API.
I looked Apple documentation and I don't see new revision. Moreover probably typo in video because there is only DetectHumanPoseRequst (swift based) and
VNDetectHumanHandPoseRequest (obj-c based) (notice lack of Human prefix in WWDC video)
First one have revision only added in iOS 18+:
https://developer.apple.com/documentation/vision/detecthumanhandposerequest/revision-swift.enum/revision1
Second one have revision only added in iOS14+:
https://developer.apple.com/documentation/vision/vndetecthumanhandposerequestrevision1
I don't see any new revision targeting iOS26+
