Apple Intelligence Integration

Integrate Apple's AI capabilities using real frameworks available in iOS 18+

🧠 What is Apple Intelligence?

Apple Intelligence is Apple's personal intelligence system that:

• Uses on-device processing for privacy
• Integrates with Siri and system apps
• Provides writing tools and smart replies
• Works across iPhone, iPad, and Mac

🔧 Real Implementation with Available APIs

1. Natural Language Processing

Use the actual NaturalLanguage framework:

import NaturalLanguage

class TextAnalyzer {
    func analyzeText(_ text: String) -> TextAnalysis {
        let tagger = NLTagger(tagSchemes: [.sentimentScore, .language, .nameType])
        tagger.string = text
        
        // Get sentiment
        let sentiment = tagger.tag(at: text.startIndex, unit: .paragraph, scheme: .sentimentScore)
        
        // Get language
        let language = tagger.dominantLanguage
        
        // Extract named entities
        let entities = extractEntities(from: text)
        
        return TextAnalysis(
            sentiment: sentiment?.rawValue,
            language: language?.rawValue,
            entities: entities
        )
    }
    
    private func extractEntities(from text: String) -> [String] {
        let tagger = NLTagger(tagSchemes: [.nameType])
        tagger.string = text
        
        var entities: [String] = []
        tagger.enumerateTags(in: text.startIndex..<text.endIndex, unit: .word, scheme: .nameType) { tag, tokenRange in
            if let tag = tag {
                let entity = String(text[tokenRange])
                entities.append(entity)
            }
            return true
        }
        return entities
    }
}

struct TextAnalysis {
    let sentiment: String?
    let language: String?
    let entities: [String]
}

2. App Intents Integration

Create Siri shortcuts that work with Apple Intelligence:

import AppIntents

struct SummarizeTextIntent: AppIntent {
    static var title: LocalizedStringResource = "Summarize Text"
    static var description = IntentDescription("Summarize the provided text")
    
    @Parameter(title: "Text to Summarize")
    var inputText: String
    
    func perform() async throws -> some IntentResult & ProvidesDialog {
        // Use actual text processing
        let summary = await createSummary(from: inputText)
        
        return .result(
            value: summary,
            dialog: "Here's your summary"
        )
    }
    
    private func createSummary(from text: String) async -> String {
        // Simple extractive summarization using NaturalLanguage
        let sentences = text.components(separatedBy: ". ")
        let keyPhrases = extractKeyPhrases(from: text)
        
        // Return sentences containing key phrases
        let importantSentences = sentences.filter { sentence in
            keyPhrases.contains { sentence.localizedCaseInsensitiveContains($0) }
        }
        
        return importantSentences.prefix(3).joined(separator: ". ")
    }
    
    private func extractKeyPhrases(from text: String) -> [String] {
        let tagger = NLTagger(tagSchemes: [.lemma])
        tagger.string = text
        
        var phrases: [String] = []
        tagger.enumerateTags(in: text.startIndex..<text.endIndex, unit: .word, scheme: .lemma) { tag, tokenRange in
            if let lemma = tag?.rawValue, lemma.count > 4 {
                phrases.append(lemma)
            }
            return true
        }
        return Array(Set(phrases)).prefix(5).map { String($0) }
    }
}

3. Core ML Integration

Use real Core ML for on-device intelligence:

import CoreML
import Vision

class ImageAnalyzer {
    private var model: VNCoreMLModel?
    
    init() {
        setupModel()
    }
    
    private func setupModel() {
        guard let modelURL = Bundle.main.url(forResource: "MobileNetV2", withExtension: "mlmodelc"),
              let model = try? VNCoreMLModel(for: MLModel(contentsOf: modelURL)) else {
            print("Failed to load Core ML model")
            return
        }
        self.model = model
    }
    
    func analyzeImage(_ image: UIImage) async throws -> [ImageClassification] {
        guard let model = model,
              let cgImage = image.cgImage else {
            throw AnalysisError.modelNotAvailable
        }
        
        return try await withCheckedThrowingContinuation { continuation in
            let request = VNCoreMLRequest(model: model) { request, error in
                if let error = error {
                    continuation.resume(throwing: error)
                    return
                }
                
                guard let results = request.results as? [VNClassificationObservation] else {
                    continuation.resume(returning: [])
                    return
                }
                
                let classifications = results.prefix(5).map { observation in
                    ImageClassification(
                        label: observation.identifier,
                        confidence: observation.confidence
                    )
                }
                
                continuation.resume(returning: classifications)
            }
            
            let handler = VNImageRequestHandler(cgImage: cgImage)
            try? handler.perform([request])
        }
    }
}

struct ImageClassification {
    let label: String
    let confidence: Float
}

enum AnalysisError: Error {
    case modelNotAvailable
}

            if !suggestions.isEmpty {

        // Detect language
        let recognizer = NLLanguageRecognizer()
        recognizer.processString(text)
        if let detectedLanguage = recognizer.dominantLanguage {
            language = Locale.current.localizedString(forLanguageCode: detectedLanguage.rawValue) ?? detectedLanguage.rawValue
        }
        
        // Generate simple suggestions based on text analysis
        generateSuggestions(for: text)
    }
    
    private func generateSuggestions(for text: String) {
        let tagger = NLTagger(tagSchemes: [.lexicalClass])
        tagger.string = text
        
        var nouns: [String] = []
        tagger.enumerateTags(in: text.startIndex..<text.endIndex, unit: .word, scheme: .lexicalClass) { tag, tokenRange in
            if tag == .noun {
                let noun = String(text[tokenRange])
                nouns.append(noun)
            }
            return true
        }
        
        // Simple suggestion logic
        suggestions = Array(Set(nouns)).prefix(3).map { "related to \($0)" }

    @State private var searchText = ""
    
    var filteredNotes: [Note] {

🔒 Privacy Best Practices

On-Device Processing

class PrivacyFirstProcessor {
    func processText(_ text: String) -> ProcessedResult {
        // All processing happens locally
        let tagger = NLTagger(tagSchemes: [.sentimentScore])
        tagger.string = text
        
        let sentiment = tagger.tag(at: text.startIndex, unit: .paragraph, scheme: .sentimentScore)
        
        return ProcessedResult(
            sentiment: sentiment?.rawValue ?? "neutral",
            processedLocally: true
        )
    }
}

struct ProcessedResult {
    let sentiment: String
    let processedLocally: Bool
}
