# Platform-Specific Guides

> Platform-Specific Guides — Zixflow iOS SDK integration guide.

### UIKit vs SwiftUI

#### UIKit Initialization

Use `AppDelegate` for UIKit apps:

```swift theme={null}
@main
class AppDelegate: UIResponder, UIApplicationDelegate {
    func application(
        _ application: UIApplication,
        didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
    ) -> Bool {
        // Initialize SDK here
        Zixflow.initialize(withConfig: config)
        return true
    }
}
```

#### SwiftUI Initialization

Use `@UIApplicationDelegateAdaptor` for SwiftUI apps:

```swift theme={null}
@main
struct YourApp: App {
    @UIApplicationDelegateAdaptor(AppDelegate.self) var appDelegate

    var body: some Scene {
        WindowGroup {
            ContentView()
        }
    }
}
```

#### Screen Tracking Differences

* **UIKit**: Enable automatic screen tracking with `.autoTrackUIKitScreenViews()`
* **SwiftUI**: Manual screen tracking recommended:

```swift theme={null}
// In SwiftUI views
.onAppear {
    Zixflow.shared.screen(title: "Home Screen")
}
```

### visionOS Support

The SDK supports visionOS with limited features.

#### Supported Features

* Core DataPipelines (user identification, event tracking)
* Apple Push Notifications (APNs)
* Location tracking

#### Unsupported Features

* Firebase Cloud Messaging (FCM)

#### visionOS Setup

```swift theme={null}
import ZixflowDataPipelines

let config = SDKConfigBuilder(apiKey: "YOUR_API_KEY")
    .logLevel(.debug)
    .build()

Zixflow.initialize(withConfig: config)
```
