Deep Linking

Deep Linking Generator

Generate deep linking infrastructure with URL schemes, Universal Links, and App Intents for Siri/Shortcuts.

When This Skill Activates

• User wants to handle custom URL schemes (myapp://)
• User mentions Universal Links or Associated Domains
• User wants Siri Shortcuts or App Intents
• User needs to navigate to specific content from external sources

Pre-Generation Checks

Before generating, verify:

1. Existing Deep Link Handling

``bash # Check for existing URL handling grep -r "onOpenURL\|open.*url\|handleOpen" --include="*.swift" | head -5 ``

1. URL Scheme in Info.plist

``bash # Check for CFBundleURLTypes find . -name "Info.plist" -exec grep -l "CFBundleURLSchemes" {} \; ``

1. Associated Domains Entitlement

``bash find . -name "*.entitlements" -exec grep -l "associated-domains" {} \; ``

Configuration Questions

1. URL Scheme

• What custom URL scheme? (e.g., myapp)
• This enables myapp://path/to/content links

2. Universal Links

• Yes - Handle HTTPS links (requires AASA file on server)
• No - Custom URL scheme only

3. App Intents / Siri Shortcuts

• Yes - Enable voice commands and Shortcuts app
• No - URL-based deep linking only

4. Link Types

• Profile: /users/{id}
• Content: /items/{id}
• Actions: /actions/share, /actions/create
• Custom routes based on app needs

Key Features

Route Definitions

enum DeepLink: Equatable {
    case home
    case profile(userId: String)
    case item(itemId: String)
    case settings
    case action(ActionType)

    enum ActionType {
        case share(itemId: String)
        case create
    }
}

URL Parsing

extension DeepLink {
    init?(url: URL) {
        guard let components = URLComponents(url: url, resolvingAgainstBaseURL: true) else {
            return nil
        }

        let pathComponents = components.path.split(separator: "/").map(String.init)

        switch pathComponents {
        case ["users", let userId]:
            self = .profile(userId: userId)
        case ["items", let itemId]:
            self = .item(itemId: itemId)
        case ["settings"]:
            self = .settings
        default:
            self = .home
        }
    }
}

SwiftUI Integration

@main
struct MyApp: App {
    @State private var router = DeepLinkRouter()

    var body: some Scene {
        WindowGroup {
            ContentView()
                .environment(router)
                .onOpenURL { url in
                    router.handle(url)
                }
        }
    }
}

App Intents Integration

OpenIntent for Navigation

struct OpenItemIntent: OpenIntent {
    static let title: LocalizedStringResource = "Open Item"

    @Parameter(title: "Item")
    var target: ItemEntity

    func perform() async throws -> some IntentResult {
        await router.navigate(to: .item(itemId: target.id))
        return .result()
    }
}

App Shortcuts

struct AppShortcuts: AppShortcutsProvider {
    static var appShortcuts: [AppShortcut] {
        AppShortcut(
            intent: OpenItemIntent(),
            phrases: [
                "Open \(\.$target) in \(.applicationName)",
                "Show \(\.$target)"
            ],
            shortTitle: "Open Item",
            systemImageName: "doc"
        )
    }
}

Required Capabilities

URL Scheme (Info.plist)

CFBundleURLTypes

    
        CFBundleURLSchemes
        
            myapp
        
        CFBundleURLName
        com.yourcompany.myapp
    

Universal Links (Entitlements)

com.apple.developer.associated-domains

    applinks:yourapp.com
    applinks:www.yourapp.com

Server Configuration (AASA)

Host at https://yourapp.com/.well-known/apple-app-site-association:

{
  "applinks": {
    "apps": [],
    "details": [
      {
        "appID": "TEAMID.com.yourcompany.yourapp",
        "paths": [
          "/items/*",
          "/users/*",
          "/share/*"
        ]
      }
    ]
  }
}

Integration Steps

1. Basic URL Handling

@main
struct MyApp: App {
    var body: some Scene {
        WindowGroup {
            ContentView()
                .onOpenURL { url in
                    handleDeepLink(url)
                }
        }
    }
}

2. Universal Links (UIKit)

// In SceneDelegate
func scene(_ scene: UIScene, continue userActivity: NSUserActivity) {
    guard userActivity.activityType == NSUserActivityTypeBrowsingWeb,
          let url = userActivity.webpageURL else {
        return
    }
    handleUniversalLink(url)
}

3. App Intents Setup

1. Create entities for Spotlight indexing
2. Implement OpenIntent for each content type
3. Define AppShortcuts for Siri phrases
4. Index entities with CSSearchableIndex

Testing

URL Schemes

# Simulator
xcrun simctl openurl booted "myapp://items/123"

# Device
# Open Safari and navigate to myapp://items/123

Universal Links

# Test AASA file
curl -I "https://yourapp.com/.well-known/apple-app-site-association"
# Should return Content-Type: application/json

# Validate with Apple
# Use Apple's tool or Branch.io validator

App Intents

1. Build and run on device
2. Open Shortcuts app
3. Your app's shortcuts should appear
4. Test with Siri: "Hey Siri, [your phrase]"
