Core ML Skills

Combined advisory, generator, and workflow skill for integrating machine learning into Apple platform apps. Covers Core ML model integration, Vision framework image analysis, NaturalLanguage framework text processing, Create ML training, and on-device model optimization.

When This Skill Activates

Use this skill when the user:

Wants to add ML capabilities to their app
Needs to integrate a Core ML model (.mlmodel) into an Xcode project
Wants to use the Vision framework for image analysis (faces, text recognition, body pose, object detection)
Wants to use the NaturalLanguage framework for text processing (sentiment, entities, language detection)
Needs to train a custom model with Create ML
Wants to optimize a model for on-device use (quantization, pruning, palettization)
Needs to choose between Core ML and Foundation Models (Apple Intelligence)
Asks about image classification, object detection, sound classification, or tabular data prediction
Wants real-time camera + ML processing

Decision Guide: Core ML vs Foundation Models

Before generating code, determine which framework is appropriate.

Use Foundation Models (Apple Intelligence) When:

You need general-purpose text generation, summarization, or conversational AI
Target is iOS 26+ / macOS 26+ (Foundation Models requires Apple Silicon + latest OS)
The task is open-ended language understanding or generation
You want @Generable structured output from natural language
See apple-intelligence/foundation-models/ skill for implementation

Use Core ML When:

You need specialized ML: image classification, object detection, sound classification, custom regression/classification
You have a trained model (.mlmodel, .mlpackage) or plan to train one
You need broad device support (iOS 14+ / macOS 11+)
The task requires domain-specific predictions (medical imaging, product recognition, custom NLP)
Performance-critical inference on Neural Engine or GPU

Use Vision Framework When (No Custom Model Needed):

Image classification using Apple's built-in models
Face detection and facial landmark analysis
Text recognition (OCR) with VNRecognizeTextRequest
Body and hand pose detection
Barcode and QR code scanning
Image similarity and saliency detection
Horizon detection, rectangle detection

Use NaturalLanguage Framework When (No Custom Model Needed):

Sentiment analysis on text
Language identification
Tokenization (word, sentence, paragraph boundaries)
Named entity recognition (people, places, organizations)
Word and sentence embeddings for similarity comparison
Lemmatization and part-of-speech tagging

Pre-Generation Checks

1. Project Context Detection

Check deployment target (Core ML requires iOS 11+ / macOS 10.13+; Vision requires iOS 11+; NaturalLanguage requires iOS 12+)
Check for existing ML code or models
Identify project structure and source file locations
Determine if SwiftUI or UIKit/AppKit

2. Conflict Detection

Search for existing ML integration:

Glob: **/*Model*.swift, **/*Classifier*.swift, **/*Predictor*.swift, **/*.mlmodel, **/*.mlmodelc, **/*.mlpackage
Grep: "import CoreML" or "import Vision" or "import NaturalLanguage"

If found, ask user:

Extend existing ML setup?
Replace with new implementation?
Add additional model/capability?

Configuration Questions

Ask user via AskUserQuestion:

What ML capability do you need?
- Image classification (identify objects in photos)
- Object detection (locate objects with bounding boxes)
- Text analysis (sentiment, entities, language)
- Custom Core ML model integration
- Vision framework (OCR, faces, poses)
- Sound classification
- Tabular data prediction
Do you have a trained model, or need to train one?
- I have a .mlmodel / .mlpackage file
- I want to train with Create ML
- I want to use Apple's built-in models (Vision / NaturalLanguage)
Performance requirements?
- Real-time (camera feed, < 33ms per prediction)
- Interactive (user-initiated, < 500ms acceptable)
- Background processing (batch, latency not critical)

Core ML Model Integration

Adding a Model to Xcode

Drag .mlmodel or .mlpackage into Xcode project navigator
Xcode auto-generates a Swift class with the model name
The generated class provides type-safe input/output interfaces
Xcode compiles to .mlmodelc at build time (optimized for device)

Loading Models

// Option 1: Auto-generated class (simplest)
let model = try MyImageClassifier(configuration: MLModelConfiguration())

// Option 2: Generic MLModel loading (flexible)
let url = Bundle.main.url(forResource: "MyModel", withExtension: "mlmodelc")!
let config = MLModelConfiguration()
config.computeUnits = .all  // CPU + GPU + Neural Engine
let model = try MLModel(contentsOf: url, configuration: config)

// Option 3: Async loading (recommended for large models)
let model = try await MLModel.load(contentsOf: url, configuration: config)

Making Predictions

// Type-safe prediction with auto-generated class
let input = MyImageClassifierInput(image: pixelBuffer)
let output = try model.prediction(input: input)
print(output.classLabel)       // "cat"
print(output.classLabelProbs)  // ["cat": 0.95, "dog": 0.04, ...]

// Batch predictions
let batch = MLArrayBatchProvider(array: inputs)
let results = try model.predictions(from: batch)

Create ML Training Overview

Training Approach

Xcode Create ML App: Visual interface, drag-and-drop, no code required
CreateML Framework: Programmatic training in Swift Playgrounds or macOS apps
coremltools (Python): Convert models from TensorFlow, PyTorch, ONNX to Core ML format

Vision Framework Capabilities

Capability	Request Class	Custom Model Needed?
Image classification	`VNClassifyImageRequest`	No (built-in)
Object detection	`VNDetectObjectsRequest` (custom model)	Yes
Face detection	`VNDetectFaceRectanglesRequest`	No
Face landmarks	`VNDetectFaceLandmarksRequest`	No
Text recognition (OCR)	`VNRecognizeTextRequest`	No
Body pose	`VNDetectHumanBodyPoseRequest`	No

Image similarity	`VNGenerateImageFeaturePrintRequest`	No

Vision Request Pipeline

// Multiple requests on the same image
let handler = VNImageRequestHandler(cgImage: cgImage, options: [:])
try handler.perform([
    textRequest,     // OCR
    faceRequest,     // Face detection
    barcodeRequest   // Barcode scanning
])
// Each request's results are populated independently

NaturalLanguage Framework

Sentiment Analysis

let tagger = NLTagger(tagSchemes: [.sentimentScore])
tagger.string = "This app is amazing!"
let (tag, _) = tagger.tag(at: text.startIndex, unit: .paragraph, scheme: .sentimentScore)
// tag?.rawValue == "0.9" (positive)

Language Detection

let language = NLLanguageRecognizer.dominantLanguage(for: "Bonjour le monde")
// language == .french

Tokenization

let tokenizer = NLTokenizer(unit: .word)
tokenizer.string = "Hello, world!"
tokenizer.enumerateTokens(in: text.startIndex..<text.endIndex) { range, _ in
    print(text[range])  // "Hello" then "world"
    return true
}

Named Entity Recognition

let tagger = NLTagger(tagSchemes: [.nameType])
tagger.string = "Tim Cook visited Apple Park in Cupertino."
tagger.enumerateTags(in: text.startIndex..<text.endIndex, unit: .word, scheme: .nameType) { tag, range in
    if let tag, tag != .other {
        print("\(text[range]): \(tag.rawValue)")
        // "Tim": PersonalName, "Cook": PersonalName
        // "Apple Park": OrganizationName, "Cupertino": PlaceName
    }
    return true
}

Model Optimization

Quantization (coremltools Python)

Reduces model size by lowering numerical precision:

Float32 to Float16: ~50% size reduction, minimal accuracy loss
Float16 to Int8: ~50% further reduction, test accuracy carefully

import coremltools as ct
from coremltools.models.neural_network import quantization_utils

model = ct.models.MLModel("MyModel.mlmodel")

# Float16 quantization (safe default)
model_fp16 = quantization_utils.quantize_weights(model, nbits=16)
model_fp16.save("MyModel_fp16.mlmodel")

# Int8 quantization (aggressive, test accuracy)
model_int8 = quantization_utils.quantize_weights(model, nbits=8)
model_int8.save("MyModel_int8.mlmodel")

Palettization

Reduces unique weight values using k-means clustering:

from coremltools.optimize.coreml import palettize_weights, OpPalettizerConfig

config = OpPalettizerConfig(nbits=4)
model_palettized = palettize_weights(model, config)

Pruning

Removes near-zero weights (sparse model):

from coremltools.optimize.torch.pruning import MagnitudePruner, MagnitudePrunerConfig

config = MagnitudePrunerConfig(target_sparsity=0.75)
pruner = MagnitudePruner(model, config)

Optimization Guidelines

Always benchmark accuracy after optimization
Start with Float16 (safest, best effort-to-reward ratio)
Test on target device (Neural Engine behavior differs from GPU)
Profile with Xcode Instruments > Core ML Performance

Performance Patterns

Compute Unit Selection

let config = MLModelConfiguration()

// Best performance — let system choose CPU, GPU, or Neural Engine
config.computeUnits = .all

// CPU only — predictable latency, no GPU/NE contention
config.computeUnits = .cpuOnly

// CPU + Neural Engine — good balance, avoids GPU contention with UI
config.computeUnits = .cpuAndNeuralEngine

// CPU + GPU — when Neural Engine unavailable
config.computeUnits = .cpuAndGPU

Async Prediction for UI Responsiveness

func classify(_ image: UIImage) async throws -> String {
    let model = try await MLModelManager.shared.model(named: "Classifier")
    // Prediction runs off main thread via structured concurrency
    let input = try MLDictionaryFeatureProvider(dictionary: ["image": image.pixelBuffer!])
    let result = try await Task.detached {
        try model.predictio

    return true
}
```

## Model Optimization

### Quantization (coremltools Python)
Reduces model size by lowering numerical precision:
- **Float32 to Float16**: ~50% size reduction, minimal accuracy loss
- **Float16 to Int8**: ~50% further reduction, test accuracy carefully

```python
import coremltools as ct
from coremltools.models.neural_network import quantization_utils

model = ct.models.MLModel("MyModel.mlmodel")

# Float16 quantization (safe default)
model_fp16 = quantization_utils.quantize_weights(model, nbits=16)
model_fp16.save("MyModel_fp16.mlmodel")

# Int8 quantization (aggressive, test accuracy)
model_int8 = quantization_utils.quantize_weights(model, nbits=8)
model_int8.save("MyModel_int8.mlmodel")
```

### Palettization
Reduces unique weight values using k-means clustering:
```python
from coremltools.optimize.coreml import palettize_weights, OpPalettizerConfig

config = OpPalettizerConfig(nbits=4)
model_palettized = palettize_weights(model, config)
```

### Pruning
Removes near-zero weights (sparse model):
```python
from coremltools.optimize.torch.pruning import MagnitudePruner, MagnitudePrunerConfig

config = MagnitudePrunerConfig(target_sparsity=0.75)
pruner = MagnitudePruner(model, config)
```

### Optimization Guidelines
- Always benchmark accuracy after optimization
- Start with Float16 (safest, best effort-to-reward ratio)
- Test on target device (Neural Engine behavior differs from GPU)
- Profile with Xcode Instruments > Core ML Performance

## Performance Patterns

### Compute Unit Selection
```swift

// Best performance — let system choose CPU, GPU, or Neural Engine
config.computeUnits = .all

// CPU only — predictable latency, no GPU/NE contention
config.computeUnits = .cpuOnly

// CPU + Neural Engine — good balance, avoids GPU contention with UI
config.computeUnits = .cpuAndNeuralEngine

// CPU + GPU — when Neural Engine unavailable
config.computeUnits = .cpuAndGPU
```

### Async Prediction for UI Responsiveness
```swift

    let model = try await MLModelManager.shared.model(named: "Classifier")
    // Prediction runs off main thread via structured concurrency
    let input = try MLDictionaryFeatureProvider(dictionary: ["image": image.pixelBuffer!])
    let result = try await Task.detached {
        try model.predictio
