Mobile Package Management for TrustformeRS Python Bindings
==========================================================

This module provides comprehensive mobile package management capabilities for iOS and Android platforms,
enabling deployment of TrustformeRS models and inference capabilities on mobile devices.

Key Features:
- iOS framework generation with CocoaPods integration
- Android AAR package creation with Gradle build system
- Cross-platform mobile optimization and size reduction
- Mobile-specific configuration and deployment
- Performance profiling and monitoring for mobile environments

## Overview

TrustformeRS provides high-performance transformer model inference capabilities for iOS and Android mobile applications with HuggingFace API compatibility.

## iOS Integration

### CocoaPods Installation

Add the following to your `Podfile`:

```ruby
pod 'TrustformeRS', '~> {self.config.version}'
```

### Manual Installation

1. Download the iOS framework from releases
2. Drag `TrustformeRS.framework` into your Xcode project
3. Add to "Embedded Binaries" and "Linked Frameworks"

### Swift Usage

```swift
import TrustformeRS

// Create model
let model = TrustformeRS.createModel(name: "bert-base-uncased")

// Run inference
let result = model?.inference(input: "Hello world")
print(result ?? "No result")
```

## Android Integration

### Gradle Installation

Add to your `build.gradle`:

```gradle
dependencies {{
    implementation 'com.trustformers:trustformers-android:{self.config.version}'
}}
```

### Java/Kotlin Usage

```java
import com.trustformers.android.TrustformeRS;

// Create model
TrustformeRS.TrustformeRSModel model = TrustformeRS.createModel("bert-base-uncased");

// Run inference
String result = model.inference("Hello world");
System.out.println(result);

// Clean up
model.destroy();
```

## Performance Optimization

### iOS Optimization
- Enable Bitcode: {self.config.enable_bitcode}
- Minimum iOS Version: {self.config.min_ios_version}
- Supported Architectures: {', '.join(self.config.target_architectures)}

### Android Optimization
- Minimum API Level: {self.config.min_android_api}
- Supported ABIs: {', '.join(self._get_android_abis())}
- ProGuard: Enabled for release builds

## Model Management

TrustformeRS supports loading models from:
- Bundled assets
- Downloaded models
- HuggingFace Hub (with internet connection)

## Error Handling

Always check for null/nil returns and handle exceptions:

```swift
// iOS
guard let model = TrustformeRS.createModel(name: "model-name") else {{
    print("Failed to load model")
    return
}}
```

```java
// Android
try {{
    TrustformeRS.TrustformeRSModel model = TrustformeRS.createModel("model-name");
    // Use model
}} catch (RuntimeException e) {{
    Log.e("TrustformeRS", "Failed to load model", e);
}}
```

## Troubleshooting

### Common Issues

1. **Library not found**: Ensure native libraries are properly linked
2. **Model loading fails**: Check model name and availability
3. **Performance issues**: Verify optimization settings and device capabilities
